Fall 2010

(Click on the name of a given reporting region above to jump to its Seasonal Report)

Introduction

This compilation completes our third year of seasonal reports, marking an important milestone in the continuing effort to accumulate data on the changing distribution of birds across Arizona. Our ability to discern new trends improves as we accumulate data from more seasons to compare. Several regions this fall recorded earlier-than-usual arrivals of some migrants as well as some lingering waterfowl and late breeding records. It is unclear whether this was due to weather patterns, including warmer temperatures than usual towards the end of the season, or to more observers reporting. A bountiful juniper fruit crop in the northern part of the state may have contributed to fewer reports of some species in the southern part of the state, including Western and Mountain bluebirds and American Robins that were so numerous the year before. There were no reports of Lewis's Woodpecker anywhere in the lowlands or southern part of the state. The only species that showed signs of irrupting was Red-breasted Nuthatch. Lawrence's Goldfinch is typically an irregular species with large invasions every seven or eight years. The 10 reported this season from three regions, however, was especially low. A good number of Varied Thrushes, a casual transient and winter resident, were reported. The eight from six regions this season compares to seven from three regions in 2009 and six from four regions in 2008. The four Rufous-backed Robins, however, was a substantially lower number than the 30 reported in the fall of 2009 and 10 in 2008. There are signs, however, that the number may have picked up during the winter season.

Highlights of the season were two well-documented potential firsts for the state: a Little Gull in Mohave Co. and a Sedge Wren in Santa Cruz Co. The latter was enjoyed by many observers into the winter season. Other notable reports were a Great Crested Flycatcher on the Navajo Nation and two Groove-billed Anis, one in Apache Co. and the other in Cochise Co. With the taxonomic separation of Winter Wren and Pacific Wren this year, reports of the “eastern” form, Winter Wren are of more interest to birders. Winter Wren is listed by the ABC as a “review species” while Pacific Wren is a “sketch details” species. There were reports of each this season.

Our regional coordinators have assembled their reports for the fall season from the AZFO seasonal reports database, the Arizona-New Mexico Listserv, Northern Arizona Birding Forum, records submitted to the Arizona Bird Committee, eBird, and local sources. We encourage those who want to contribute to these reports to also submit their noteworthy sightings directly to the AZFO database. Sightings that appear only on the listserv or other sites and are not on the AZFO site may be missed or otherwise not included in the seasonal reports. Moreover, the database offers a cumulative and searchable repository of unusual sightings in the state. There are nine reporting regions, primarily defined by biological and geographical criteria, which can be viewed on an interactive map. In this report, documented sightings of species on the ABC Review List and observations of exceptionally large numbers of a species are in boldface. Many of these sightings are hyperlinked to photos on the AZFO web site. All reports of review species have had documentation submitted to the ABC and are “pending acceptance” by the ABC. Species and numbers underlined are “sketch details” species or exceptional reports (accidental or casual) for the specific region or season, and some are documented with photos at AZFO’s online Photo Documentation gallery. The list of cited observers and initials is at the end of the report. Infrequently cited observers are indicated in the text by the first initial and last name.

Abbreviations used throughout the reports include: Arizona Bird Committee (ABC), Arizona Breeding Bird Atlas (Atlas), Arizona Game and Fish Department (AZG&F), Bed and Breakfast (B&B), Campground (CG), Important Bird Area (IBA), National Wildlife Refuge (NWR), Sewage Treatment Plant (STP), State Park (SP), Wastewater Treatment Plant (WTP), Wildlife Area (WA), photographed (ph.), sound recording (s. r.), video recording (v. r.), many observers (m. ob.), on the authority of (fide), and date + (birds seen through end of season).

Abbreviations: Bill Williams Delta (BWD), Bill Williams River National Wildlife Refuge (BWR NWR), Lake Havasu City (LHC), Site 6, Pittsburgh Point, Lake Havasu City (Site 6), Havasu National Wildlife Refuge (HNWR), Bullhead City (BHC), lower Colorado River Valley (LCRV).

Weather conditions varied greatly throughout the county, as some areas experienced record-setting rainfall yet others received little or no precipitation. Although early August was hot and dry, three periods of monsoon rains developed during the month: August 7-9, 17-18, and 24-27. A severe thunderstorm, dumping over two inches of rain and hail a half-inch in diameter, was reported in Meadview on the 17th, and the Bullhead City area experienced wind damage and flash flooding on the 27th. The Hualapai Mtns. received over four inches of rain during the month and the monthly total of 1.64 inches for Bullhead City made it the wettest August since 2000. The monsoon season tapered off by mid-September resulting in dry conditions that continued until the end of November. Temperatures throughout Mohave Co. averaged near to above normal between August and mid-November. Lake Havasu City recorded a high of 113° F. on 5 August and Bullhead City reached 114° F. five times between 16 and 26 August. However, by the third week of November a cold front moved in bringing high winds and below-average temperatures. Although the county experienced unusual weather conditions during this season, it is doubtful that the conditions significantly affected the presence or absence of specific bird species. Most of the published records from the LCRV appear in the Birds of the Lower Colorado River Valley (Rosenberg, K. V. et al. 1991), which remains the comparison standard for reports from that area.

Usually found in small groups of two to seven birds, the report of 45 Greater White-fronted Geese 16 Sep in the BWD is noteworthy (KB). Rare but regular visitors to the LCRV, three Wood Ducks were in Pintail Slough (HNWR) 4 Nov (DDe, JPar), and two males were observed among the Mallards at the Katherine Landing docks 28 Nov (DDe). Blue-winged Teal are usually found in small groups numbering less than five with a maximum report of 10, 1 July 1977 (Rosenberg et al.), so the reports of 12 in the BWD 16 Sep (KB) and another group of 11 in the BWD 28 Oct (KB, JRi) are unusual. As they are seldom seen in the LCRV between November and January, the sighting of five Blue-winged Teal in the BWD 12 Nov is interesting (JRi). An early arriving Canvasback showed up at the BWD 28 Oct (KB, JRi), and a large flock of 350, which may be the second highest state count, was found at the north end of L. Havasu 26 Nov (PL). Redhead is also usually found only in groups of up to 10 individuals, so a flock of 39 on 4 Nov and another flock of 31 on 12 Nov in the BWD are noteworthy (JRi). Small numbers of Greater Scaup found among the more common Lesser Scaup have been reported in the LCRV since 1976. However, this fall record numbers of Greater Scaup, far outnumbering Lesser Scaup, have been reported in the BWD: 81 on 15 Nov and 97 on 23 Nov (JRi), and a maximum number of 125 on 26 Nov (PL). The all-time previous maximum count of Greater Scaup noted by Rosenberg et al. was 25. Six Surf Scoters at BWD 21 Nov and five there 25 Nov (LHar, DVP) were higher than usual numbers. One to five Barrow’s Goldeneyes were found in the BWD (LHar, DVP, JRi, PL) 21 Nov+. Observed every winter since 1976, but still rare in the LCRV, one Pacific Loon was seen from Pittsburgh Point, L. Havasu 22 Oct (JSab), five were seen from Pittsburgh Point, 22-23 Nov (LHar, DVP), and one was reported at the BWD 23 Nov (JRi). A Common Loon was an uncommon sight on L. Havasu 21 Sep (DSt). They are considered rare in the LCRV before October. The greatest number of Common Loons this fall was eight on n. L. Havasu 22 Nov (LHar, DVP), of which five were on the Arizona side of the lake.

Horned Grebe sightings included three in the BWD 27 Oct (JRi); one 23 Nov in the BWD (JRi); two at the north end of L. Havasu 23 Nov (LHar, DVP); and three at the n. end of L. Havasu 26 Nov (PL). A very early transient American White Pelican was reported 26 Aug on s. Topock Marsh (DDe) and four more were found near the BWR NWR headquarters 31 Aug (KB). The increasing appearance of Brown Pelicans, particularly adults, in the northern part of the LCRV is noteworthy. Three were seen from the northwest side of Pittsburgh Point 23 Nov (LHar, DVP), 13 were reported at the BWD 23 Nov (LHar, DVP), and six, perhaps a remnant of those seen 23 Nov, were at the BWD 25- 26 Nov (PL). These pelican occurrences followed a strong wind event with winds from the southwest. A Neotropic Cormorant continued to be observed in the BWD from 25 Sep+ (JY, KB, JRi, LHar, DVP). Seldom seen at HNWR, one Cattle Egret was on a snag in n. Topock Marsh 26 Aug (DDe). An uncommon to fairly common transient in small flocks from late July through October, 1400+ White-faced Ibis, in waves of 50 to several 100, were reported flying out of the agricultural fields in s. Mohave Valley 8 Sep (KB). A large flock of 390 White-faced Ibis flew over Beal L., HNWR, 23 Sep, (DDe).

On the early side, a first-of-season Northern Harrier appeared 11 Aug in Pintail Slough, HNWR (DDe), and a second was reported 27 Aug near n. L. Havasu (CBab). Apparently increasing as a fall and winter visitor to the region, a Red-shouldered Hawk was observed flying over a small pond in Pintail Slough 16 Sep (DDe). Between 21 Oct and 4 Nov a white American Coot was in the BWD (JRi). Uncommon from July to early September, one Snowy Plover was at Site 6 on 26 Aug (ph. CBab) and another was at Rotary Park, LHC 6 Sep (ph. JWe). The fall migration period for American Avocets is usually over by mid-October, so the arrival of a flock of 46 in the BWD 1 Nov was late (KB, JRi). Rare after late August, 11 Marbled Godwits were at Beal L., HNWR 16 Sep (DDe ph.). An unusually large flock of 150-200 Red-necked Phalaropes was reported 21 Sep at BWD (DSt).

A number of significant gull sightings were made in the northern part of the LCRV during the season. Sabine's Gulls have recently become rare but regular fall migrants in Arizona, but a juvenile on the late date of 21 Nov off of Pittsburgh Point, LHC was exceptional (MsT, SSt). A small odd gull observed and photographed from a boat in s. Mesquite Bay, L. Havasu 23 Sep was later identified as a juv. Little Gull (JSab, ph. BSu). If accepted by the ABC this will be a long overdue first state record and the last of the lower 48 states to add it to their state list. A very casual visitor to Arizona, a Western Gull was first discovered at Rotary Park, LHC 4 Sep (ph. JWe). Many reports for this gull were submitted throughout September with the last reported sighting 18 Oct (LHar, DVP). Another very casual visitor to the state, a juv. Thayer’s Gull was photographed at Rotary Park 22 Nov (ph. DVP, LHar). An exceptional concentration of 24 Caspian Terns at Beal L. HNWR 16 Sep was an impressive sight for Arizona (ph. DDe).

Other Noteworthy Gull and Tern Species Sightings in N. LCRV

During September three Parasitic Jaegers and two Long-tailed Jaegers were observed at various locations on L. Havasu. The first Parasitic Jaeger was reported 14 Sep near Rotary Park, LHC (ph. BSu). A photograph of the bird showed that it had a misshaped bill. A second Parasitic Jaeger, with a normal bill, was found near n. Mesquite Bay, L. Havasu 18 Sep (TL, JLo). The next day, two juv. Parasitic Jaegers were reported north of Site 6 chasing each other (ph. TBen, m. ob.). One juv. Parasitic Jaeger was observed chasing a small gull in n. Mesquite Bay 20 Sep (DDe), and one was spotted from Pittsburgh Point 21 Sep (MSt, DSt). The last report of a Parasitic Jaeger was made 23 Sep as one was seen chasing a Sabine’s Gull in n. L. Havasu (JSab, BSu). A casual transient on L. Havasu, a Long-tailed Jaeger was observed 18 Sep at n. Mesquite Bay (TL, JLo) and seen the next day north of Site 6 eating a Savannah Sparrow (ph. TBen, m. ob.). A Long-tailed Jaeger, likely the same one, was reported near Pittsburgh Point 21 Sep (MSt, DSt).

Accidental for the region, a Ruddy Ground-Dove occurred 17 Oct at a golf course near Rotary Park, LHC (DVP, LHar). Most sightings of this species in the LCRV have come from Parker south. Rare but regular visitors, three Golden-crowned Kinglets were near the Hwy 95 gate, BWR NWR 9 Nov (JRi). A casual fall visitor to the region, a Varied Thrush was at the Mohave Community College administration building, Kingman 9 Oct (MPr). Sage Thrasher is a rare fall transient, so it was noteworthy that one was found at Pintail Slough 16 Sep (DDe). A slightly late migrant, one Black-throated Gray Warbler was found near the Hwy 95 gate, BWR NWR 9 Nov (JRi). Casual anywhere in the state, a juv. female Black-throated Green Warbler was banded at Beal Restoration Site HWNR 8 Oct (CDo, ph. JK). An imm. American Redstart was observed at N. Dike, HNWR 11 Aug (DDe) and an adult female was at Rabbit Crossing, LHC 9 Nov (KB). Dickcissel is a rare and irregular fall transient in the LCRV, so the discovery of one 17 Oct at a golf course next to Rotary Park, LHC was extraordinary (ph. DVP, LHar). Unlike last fall, there were few reports of Lawrence's Goldfinch in Arizona this season, so an individual with a group of Lesser Goldfinches at the Mt. Trumbull (Nixon Administration Cabin) 23 Sep (B. Bock) was quite noteworthy. There are very few records of this goldfinch in the Arizona Strip region of the state.

Perhaps due to mild weather during the breeding season, many species were recorded raising multiple broods this year and feeding young well into August and September. In a few cases, breeding dates exceeded those recorded in the Atlas. Migrants tended to linger late in the region. Following storms in October, several notable rarities were reported during October and November.

An early Greater White-fronted Goose was at Kachina Wetlands 31 Aug (TL). Another visited CCC ponds 10 Nov (JWi); one seen 22-30 Nov at the same location may have been the same individual (GH, JCn). Apparently returning for its fifth winter, the CCC Eurasian Wigeon was reported 19 Nov+ (JWi). A Cinnamon Teal at the I-40 Wetlands 22 Oct was slightly on the late side (JWi). Rare fall migrants, a pair of Hooded Mergansers were seen on Ashurst L. 23 Nov (JWi).

Pacific Loon is casual in Arizona away from the LCRV, so two on Upper L. Mary 17 Nov was an excellent sighting (ErH). Common Loons are more expected, though still rare. Two to five individuals were present on Upper L. Mary 7-22 Nov (ph. ErH, JWi). One visited Ashurst L. 18 Nov (JWi). A casual to rare fall visitor to the region, a Horned Grebe was a good find on Upper L. Mary 14 Oct (ph. StB, m. ob.). Another, or the same individual, was at this location 7-23 Nov (ph. ErH). Eared Grebes on Marshall L. 31 Aug included two broods of dependent chicks (EM). This date is more than two weeks later than Atlas breeding records. Rare and local in the region, one to three Clark’s Grebes were on Upper L. Mary 7-19 Nov (ErH).

Brown Pelican is casual in the region, with few records for northern “inland” Arizona, so an adult on Upper L. Mary 21 Nov was exceptional (JoH). This was part of an influx of primarily adult Brown Pelicans into the state this fall. Green Herons are rare in the Flagstaff area; an individual at the I-40 Wetlands 14-31 October was rather obliging (JWi, m. ob.). The latest Atlas date for dependent young American Coots was 3 Sep, so a report of six chicks at White Horse L. 30 Sep (ph. JWe) was astounding!

At the Grand Canyon Hawk Watch Int’l site at Yaki Point, five Broad-winged Hawks were reported 26-29 Sep (FG), typical dates for this species there.

Several migrant shorebirds were reported this season moving later than usual. Especially unseasonable was a single American Avocet on Ashurst L. 18 Nov (JWi); this species typically departs the region by October. A Spotted Sandpiper on Kaibab L. 4 Oct was on the late side (ph. JWe). Most Solitary Sandpipers move through in August, so one at Rimmy Jim Tank 12 Sep (JWi, JLo, TL) and one at Kaibab L. 30 Sep (ph. JWe) were of interest. A Greater Yellowlegs was later than expected at Mormon L. 15 Nov (D. Bray). Always a rare migrant, a Pectoral Sandpiper stopped at Rimmy Jim Tank 12 Sep (JWi, JLo, TL). Red-necked Phalarope is an uncommon migrant in the region, seen mainly in August and September. Four were reported from Walnut Canyon Ponds 13 Sep (S. Messinger), and two lingered at Rimmy Jim Tank 8 Oct (JWi). Wilson’s Phalarope, on the other hand, is chiefly an August migrant, so one on Walnut Canyon Ponds 3 Oct was exceptional (EM). An adult Herring Gull stopped at Upper L. Mary 7 Nov (ErH); this species is a rare migrant away from the Colorado R.

At least one of the White-winged Doves that summered at Elden Spring continued there until 24 Sep (ph. GBo, JWi). One at Lee’s Ferry 18 Sep was exceptionally far north (BGa), and another was in Doney Park 2 Nov (ph. PKo), where this species has wintered in recent years. Although hummingbirds were scarce and late to arrive this summer, they reached their usual abundance this fall. Anna’s Hummingbirds continue to gain a foothold in the Flagstaff area. At least three remained at Elden Spring this fall, with the last report on 9 Oct (JWi). One was found at Logan’s Crossing near Flagstaff, where they are still rare 8 Aug (KM), but one at Desert View 8-9 Oct was casual at GCNP (BGa). The latest report in the region was in Doney Park 21 Oct (ph. PKo).

A hatch-year Yellow-bellied Sapsucker at Phantom Ranch 21-23 Oct (ph. JWe) was only the fourth for GCNP. An apparent Red-naped x Red-breasted Sapsucker hybrid was reported from the I-40 Wetlands 26 Oct (JWi). Downy Woodpeckers are rare residents in aspen forest on the South Rim of the Grand Canyon, so one at a feeder near Grand Canyon Village 28 Nov was of interest (JWe).

A “Western” Flycatcher at Desert View 4 Aug was early for a migrant (BGa). Although Pacific-slope Flycatcher is the expected “Western” Flycatcher in the Arizona lowlands, its occurrence is not well documented or understood in the highlands where it may overlap with Cordilleran Flycatcher. A calling Pacific-slope Flycatcher at Elden Spring 13 Aug was, therefore, noteworthy (JCn).

Several Gray Vireos lingered near breeding areas this fall. One was near Williams 16 Sep and another was seen west of Valle 17 Sep (both RR). One at Desert View 23 Sep was about a month late (BGa). A Cassin’s Vireo in Doney Park 11 Oct was also slightly late (ph. PKo). Hutton’s Vireo is casual above the Mogollon Rim; one was described from Dogtown L. near Williams 25 Sep (ZZ). Casual in n. Arizona, a Varied Thrush made a brief stop in Flagstaff 15 Oct (ph. L. Schwebke). Four American Dippers were reported along Bright Angel Cr., Phantom Ranch, GCNP 10-11 Nov (ph. JWe). Dippers are known in the inner canyon but seldom reported.

Black-throated Gray Warblers typically depart the county by the end of September, so two in Tusayan 5 Oct were late (BGa). A Grace’s Warbler on the Mogollon Rim north of Strawberry 2 Oct was about two weeks later than expected at this elevation (BIs). An obliging adult male American Redstart, a casual to rare migrant, stopped over at Logan’s Crossing 10-28 Aug (JLo, m. ob.). A MacGillivray’s Warbler on Mt. Elden 10 Oct was on the late side for that elevation (JGr). Red-faced Warblers tend to depart their breeding areas early and are typically absent by the end of August. One at Elden Spring 1 Sep was on the late side (JWi, ph. GBo).

Further evidence of Black-chinned Sparrows breeding on Mt. Elden, a juvenile was found 5 Aug very close to where adults were noted this summer (JWi). Scarce in the Flagstaff area, individual Black-throated Sparrows were at Logan’s Crossing (JLo) and Elden Spring (PKe and BCo), both 10 Aug. Lark Buntings are rare migrants in the region, occurring mainly in August and September. Exceptional sightings this fall were of a male near Valle 18 Nov and two females near Red L. 23 Nov (both RR). Rare but regular migrants, two Fox Sparrows were reported this fall, one at Picture Canyon 30 Sep (JLo) and one at Elden Spring 4 Oct (JWi). More unusual were two Swamp Sparrows together at the I-40 Wetlands 21-23 Oct (ph. JWi).

Hepatic Tanagers seemed to be on a particularly late schedule this fall. A male with two begging young at Mars Hill 16 Aug (ZZ) was a few days later than Atlas records. Lingering migrants included a male in Doney Park 25 Sep (ph. PKo) and two on the Mogollon Rim north of Strawberry 2 Oct (BIs). A vagrant Dickcissel visited Vermillion Cliffs 23 Sep (ph. SPu).

A Brown-headed Cowbird near Grand Canyon Village 28 Sep (JWe) and a Bullock’s Oriole at Logan’s Crossing 14 Sep (JLo) were both on the late side. It was an average season for irruptive finches, with a few reports of small numbers away from breeding areas of Cassin’s Finch, Red Crossbill, Pine Siskin, and Evening Grosbeak.

Navajo and Hopi Nations

Early fall was especially productive in this region. A number of unusual eastern vagrants attracted birders to the Cameron Trading Post and Seep through September, and the Colorado R. canyon produced several noteworthy observations. However, reports from the region were scarce after late September.

A Common Goldeneye was reported below Glen Canyon Dam 19 Sep (SPu). This is an early date for a migrant, suggesting the possibility that it summered, as they occasionally do. A rare Horned Grebe was found at the Page STP 9 Nov (SPu).

Three Neotropic Cormorants were discovered on the Colorado R. upstream of Lee's Ferry in Glen Canyon near Water Holes Canyon 12 Aug (SPu) and seen subsequently until 21 Sep (ph. BGa, JWe m. ob.). This represents the apparent first record of this species in Coconino Co, the Navajo Nation, and the Grand Canyon region.

Shorebird sightings were sparse. Sanderlings are rare visitors to the region, so a report of two at the Page STP 13 Sep (JM et al.) was notable. On the same day a single juv. Sabine's Gull was also reported from the Page STP (JM et al.).

A Black Phoebe was late near Tuba City 17 Nov (CLR). On 19 Sep a Great Crested Flycatcher was discovered at the Cameron Trading Post (CLR, ph. TL, m. ob.). The bird was seen and photographed by many in the courtyard of the trading post until the morning of 21 Sep. With only four previous records in Arizona, this was the most unusual of the eastern vagrants that turned up in Cameron this year. Eastern Kingbird, casual in Arizona but perhaps more common in the ne. corner of the state, was reported from the Cameron Seep 26 Aug (JWi). A Gray Vireo found near Cameron Seep 11 Sep (CLR, JLo, TL) was notable as a late migrant through the area.

An Orange-crowned Warbler at Cameron Seep 17 Nov (CLR) was a late migrant. In the courtyard of the Cameron Trading Post a Kentucky Warbler was discovered 16 Sep (BGro). The bird stayed until the following morning (ph. JLo, SPu). Even though Northern Waterthrush and American Redstart are the most common "eastern" warblers seen in the region, their presence is still notable. At Cameron seep a single Northern Waterthrush was reported 24 Aug (JWi), two were present 26 Aug (JWi), and one was reported 9 Sep (JM et al.). A single female American Redstart was found at Cameron Seep 9 Sep (JM) and then reported by numerous observers through 22 Sep.

A survey of the western portion of the Navajo Nation produced the latest record of Scott's Oriole for the Navajo Nation near Lee Canyon 31 Aug (CLR). Begging fledgling Lazuli Buntings at Cameron Seep 24 Sep (ErH), was a late date for feeding young, especially in the northern part of the state.

Yavapai

Always migrating through Arizona earlier in the fall than other geese species, an exceptional flock of 26 Greater White-fronted Geese visited Willow L. 3 Sep (SD, DM). Another individual arrived there 24 Sep and remained through the period (CT, m. ob.). Snow and Ross’s Geese are rare but regular fall migrants in the region. Therefore of note was an imm. Snow Goose, first noted at Willow L. 23 Oct (SuB, et al.), that remained until 27 Nov (m. ob.). A Ross’s Goose rested at Willow L. 15-16 Nov (DM, MN). Another rare but regular late fall migrant, an adult Tundra Swan was noted at Willow L. 27 Nov-1 Dec (StB, SuB), then two imm. swans settled at Watson L. 28 Nov (CT). All three birds commuted between the two lakes, at times as a group, through the end of the period (m. ob.).

Infrequent in the Prescott area, three Blue-winged Teal noted at Watson L. 23-24 Sep (CT, StB) and two at Willow L. on 24 Sep (DM) were of interest. Yavapai Co.’s first breeding records for Northern Shoveler and American Wigeon were established 13 Aug at Willow L. (CT). Ducklings following an adult female American Wigeon continued to grow through the fall and older fledgling Northern Shovelers also remained together for several weeks (CT). Only casually nesting in the region, two family groups of Northern Pintails were also resident there as well (CT). Considered accidental in the region, four Surf Scoters were discovered at Lynx L. 31 Oct (ph. SD, DM, CT, StB, SuB). Casual at Prescott, nine Red-breasted Mergansers were noted at Willow L. 6-7 Nov (SD, DM).

A hen Gambel’s Quail discovered incubating a clutch of 10 eggs in a Cottonwood yard 17 Aug (RR) was an exceptionally late nesting attempt, particularly for central Arizona. Although uncommon to common migrants along the lower Colorado R., Common Loons are rare but regular fall migrants elsewhere in Arizona. Therefore of note was one at Watson L. 25 Oct (KAr). The bird was joined by at least two others 2 Nov (SD), with one remaining through at least 16 Nov (MN). Two American White Pelicans also foraged at Watson L. 24 Sep (StB, SuB, CT, et al.) with one remaining through 28 Oct (m. ob.).

A late Turkey Vulture lilted over Willow L. 24 Nov (E. Moore, C. Tenney). An Osprey at Page Springs 27 Nov was late for the Oak Cr. area (ph. GBo). Nearly all Common Black-Hawks have departed Arizona by mid-October, so a lingering individual noted 6 Nov at Page Springs (GBo) and that stayed through the end of the period was of special note. Oddly, during the past 15 years a Common Black-Hawk has remained through the winter at this location at least two to three different years (fide RR). A family of Harris’s Hawks fledged two young near Dewey, the northernmost breeding site in Yavapai Co. An adult was incubating eggs on the rather late date of 11 Aug with another adult nearby. Two nestlings noted 10 Sep were observed as vocal fledglings in another tree not far from the nest 10 Oct (CT). A rather late American Avocet was noted at Willow L. 1 Nov (CT). With very few documented records and considered accidental in the Prescott region, a Semipalmated Sandpiper at the Prescott Airport recharge ponds 14-15 Aug was a surprise (ph. CT, et al.). Infrequent and uncommon in the Prescott area, a single Pectoral Sandpiper visited Willow L. 31 Aug (CT). Short-billed Dowitchers are casually reported in the region so one discovered 11 Oct at Watson L. (DVP, LHar) and observed through 13 Oct (m. ob.) was noteworthy. Two Wilson's Phalaropes reported at Willow L. 3 Nov (DM) were late.

Infrequently reported in the region, a Bonaparte’s Gull was discovered among an exceptional concentration of 94 Ring-billed Gulls at Willow L. 16 Nov (MN). Terns are infrequently noted in the Prescott region, so three species at Willow L. 31 Aug was exceptional. This included a casually reported Common Tern (SD), plus three Caspian Terns and one Forster’s Tern, which are rare but regular fall migrants (CT, SD, et al.).

Inca Doves are sparse, local, and apparently declining residents in the middle Verde Valley, so of note was one discovered 12 Nov at Page Springs (G. Hornberger). Accidental in Yavapai Co., a Ruddy Ground-Dove was photographed while visiting feeders 11-21 Oct in Chino Valley (ph. C. & R. Wuerhmann). A Northern Pygmy-Owl called periodically 23 Sep through November near Granite Basin L., which is a location where they are infrequently detected (K&JA, SD, CT).

Accidental in the region, a male Broad-billed Hummingbird visited feeders in north Prescott 9-13 Oct (B. Bockrath; ph. B. and M. Tinney). Irregular migrants, single Lewis’s Woodpeckers appeared at Granite Basin 15 Oct (CT) and 19 Oct at feeders near Walker south of Lynx L. (J. & V. Morhous). Then 15 Nov three arrived at these same feeders and stayed through the month. Typically a resident below 4800 ft. elevation in Yavapai Co., Gila Woodpeckers are casually seen in the Prescott area and elsewhere at higher elevation with nearly all records in fall or winter. This fall there were exceptional numbers of these wandering individuals. A male found in Granite Basin 10 Nov (MN, MiR) was probably the same bird first reported 2 Oct (DM) and recorded intermittently through the period (m. ob.). Single Gila Woodpeckers were also observed along Grapevine Cr. near Poland Junction 10 Oct (TC, DVP, LHar, et al.), in Copper Basin on 14 Oct (CT et al.), and along Bannon Cr. northwest of Goldwater L. 18 Oct (SD et al.). A female Downy Woodpecker (casual in Prescott region) was noted in Watson Woods Preserve 18 Nov (DM).

Both Western-type Flycatchers and Warbling Vireos typically have departed Arizona by early to mid-October, so individuals of each observed 11 Nov at Montezuma Well were exceptional (JWi). Ten American Crows were found in Williamson Valley 8 Oct (DM et al.). Their distribution northwest of Prescott is not well understood. Barn Swallows were still feeding nestlings and fledglings on 11 Aug near Dewey (CT). A solitary Verdin at an upland grassland/riparian site along Williamson Valley Wash northwest of Prescott 8 Oct was far removed from its usual desert shrub habitat (DM et al.). Irregular migrants and winter visitors in the Prescott area, Red-breasted Nuthatches arrived in this area during October. Small groups totaling over 25 remained at Granite Basin throughout the period (CT, DM, m. ob.). Two Pacific Wrens were detected along Grapevine Cr. near Poland Junction 19 Nov (MN). These wrens are basically rare but regular migrants and winter visitors through the region although numbers vary from one year to the next. Casual migrants to the region, an adult male Varied Thrush was discovered along the upper Verde R. near Paulden 24 Oct (MN).

An Olive Warbler observed along Grapevine Cr. near Poland Junction 10 Oct was at a lower elevation than expected (LHar, DVP, et al.). A rare but regular migrant through the region, a Northern Parula discovered in cottonwood-willow forest at Watson Woods Preserve south of Watson L. 18 Nov (DM) may have been the same individual noted there 27 Nov (B. Percival, JT; StB, SuB, et al.). Chestnut-sided Warblers are casually reported migrants in the region, but this fall there were two with the first at Montezuma Well 11 Nov (JWi) and the second at the Watson Woods Preserve 27 Nov (ph. B. Percival, JT, StB, SuB, et al.). Another casual migrant through the region, a bright male Black-throated Blue Warbler appeared along Grapevine Cr. north of Big Bug Mesa and south of Humboldt 19 Nov (MN). Black-and-white Warblers are one of the more regular rare migrants through Arizona, but are still of note. One resided in a cottonwood grove at Willow L. from 9 Nov+ (MN, m. ob.) Another Black-and-white Warbler was at Montezuma Well 11-12 Nov (JWi, ErH), and a third foraged in a mixed species flock at lower Goldwater L. 24 Nov (MiR). A calling Northern Waterthrush, another rare but regular migrant through Arizona, foraged under cottonwood-willow gallery along Granite Cr. in Prescott 13 Aug (CT). A secretive Yellow-breasted Chat along Granite Cr. 7 Sep was Prescott’s only fall record for this infrequently observed warbler (DM).

On 11 Aug, a singing Cassin’s Sparrow was located not far from the site where one was noted in grassland east of the Agua Fria R. near Dewey 18 Jul (CT). It was a respectable breeding season for some open-country sparrows with both Lark and Black-throated Sparrows still feeding fledglings 1 Aug in the western part of the region (RR). Casual migrant in the Prescott area, a Grasshopper Sparrow foraged with a mixed sparrow flock in grassland near the Prescott airport recharge ponds 17 Oct (CT).

Rare but regular migrants and winter visitors to the region, four (Slate-colored) Fox Sparrows were near Granite Basin L. 2 Oct (DM) and another was along Grapevine Cr. 10 Oct (TC). On 11 Aug, Song Sparrows that were observed in dense vegetation along the Agua Fria R. near Humboldt 18 Jul were feeding fledglings, thus confirming a new nesting location (CT). One pair fed a fledgling Brown-headed Cowbird (CT). Swamp Sparrows are rare but regular migrants and winter visitors to Arizona, so of note was one along Watson L. 11 Oct (DVP, LH) and another at Page Springs 13 Nov (KM).

A pair of Hooded Orioles feeding nestlings in a riparian patch within chaparral south of Prescott 12 Aug was a rather late nesting effort for central Arizona (CT). Unlike last year, there were very few reports of Lawrence’s Goldfinches this fall in Arizona so of interest was one at Williamson Valley 15 Aug (A&NS), a male observed northwest of Prescott 30 Sep (BS), and five at Granite Basin on 15 Oct (CT). Rarely seen in recent years in the region, two Evening Grosbeaks were noted calling in flight over Hassayampa Cr. north of Mt. Tritle 12 Oct and two flew over Lynx L, 19 Oct (both CT).

The last half of the monsoon season continued to bring average to above-average precipitation to the region with an abundance of food resources for birds. This likely caused many species to be more dispersed than concentrated at sites like feeding stations. This was shown by lower numbers and the absence of some species (e.g., warblers, starlings) where they are usually present during the fall. However, low hummingbird numbers at feeders even before the monsoon season suggests that dispersed feeding was not involved in the noted shortages. Movement of higher elevation species such as Red-breasted Nuthatches and Pine Siskins into the lowlands or in above-average numbers was also recorded.

Greater White-fronted Geese occur uncommonly in early fall. At the Golf Course Rd. WTP in Holbrook four were reported 4 Sep (ErH et al.) and five were there 6 Sep (ErH). At the Springerville WTP two birds were found 17 Sep (CBab, BJ). Rare visitors in late fall to the region, Snow Geese were observed twice this season with one in Joseph City 4 Nov (ElH, BHo) and one at Wenima WA near Springerville 27 Nov (ErH et al.). One Hooded Merganser was at the unnamed reservoir behind HCGC in Holbrook 13 Nov (ErH, ElH), and an unusually large raft of 24 birds was reported from Scott Res. in Pinetop-Lakeside 26 Nov (LL). This species is considered an uncommon to rare migrant across the region.

Likely due to the isolated location of bodies of water in this region, egrets are decidedly rare to uncommon visitors. Several Snowy Egrets appeared this season, however, with five at Show Low L. 17 Sep (LPen) and two at Becker L. 22 Sep (SH).

Zone-tailed Hawk is a rare transient above the Rim in summer, so one seen in Pinedale 17 Aug (ErH, BHo) was noteworthy. Merlins are uncommon migrants in the fall, with most birds occurring from late September through November. Slightly early observations this fall were of one in Eagar 6 Sep (SH) and another at the Springerville WTP 17 Sep (CBab, BJ), with a later sighting of one along Zeniff Rd. near Dry L. 25 Nov (ErH, ElH).

Several attempts have been made to introduce non-native game birds into the state. The only population of California Quail in the state, for example, was introduced in the 1960s along the Little Colorado R. between Springerville and St. Johns. This population still persists in the Richville Valley with at least 12 birds in a few coveys observed 7 Aug (ph. JLo, TL).

Sabine’s Gulls are rare and irregular visitors to the region in midfall, with most sightings pertaining to first-year birds. One first-year gull was a noteworthy find at Sunrise L. 24 Sep (SH). Caspian Tern is a casual to rare migrant through the region, with most records for Apache Co. One was seen in the county 5 Sep at Sunrise L. (SH), where some of the previous reports have come from.

The rarest observation this fall was of a Groove-billed Ani at Wenima WA 1 Aug (ph. MCl). This species is a casual vagrant in the state and accidental in the region. There is only one previous record for both the region and Apache Co. at Lyman L. in 1967 (Monson and Phillips 1981). Other reports in n. Arizona have been from the Grand Canyon and the confluence of the Colorado R. and Little Colorado R. (fide BGa, ZZ).

Spotted Owl is a rare resident in the region, with much of the species’ habitat destroyed along the Rim by the Rodeo-Chediski fire of 2002. Therefore, reports of this species still utilizing the remnant mixed conifer groves in the area is valuable knowledge. One bird was encountered in Black Canyon south of Heber 22 Aug (ph. ErH et al.). Belted Kingfisher is an uncommon migrant from early to midfall, but is rare in late fall and winter in the White Mtns. One at Wenima WA 27 Nov (ErH et al.) was on the late side. There are previous winter reports for this species in the region (Phillips et al. 1964), so individuals may remain through periods of colder temperature as long as open water exists for them to forage in.

Magnificent Hummingbirds are rare visitors in the region following breeding, with increasing reports coming from above the Rim in recent years. However, no sightings had occurred as far north in the region as Snowflake until one was spotted at feeders 28 Sep (GHo). Anna’s Hummingbirds are another species that has been increasingly seen in the northern part of the state in the past decade, with past reports coming from Heber-Overgaard northwest to Flagstaff. This fall one bird was in Pinetop-Lakeside 18 Sep (GW, EWe) and another present in Show Low 4 Oct (GHo).

Red-naped Sapsuckers are breeders and common migrants in the region, but the observation of 20 individuals at Sipe White Mtn. WA 24 Sep (SH) was an unusually high count. A common fall migrant in habitats as low as pinyon-juniper woodlands, one Williamson’s Sapsucker was unusual at lower elevation Petrified Forest NP 3 Sep (KBa). American Three-toed Woodpeckers have repeatedly been encountered along the Rim in Black Canyon south of Heber east to the Pinetop-Lakeside area since 2009. Presumably the birds invaded the burn area from the Rodeo-Chediski fire of 2002 either from the White Mtns. or from populations farther west along the Rim. Besides burn areas, sightings of this species have come from adjacent second-growth forests with stressed trees. This fall one bird was at Woodland L. Park in Pinetop-Lakeside 1 Aug. (GW et al.) and another was near Black Canyon L. 22 Aug (ErH et al.).

Willow Flycatchers are a rare migrant through the region, so one along Golf Course Rd. WTP in Holbrook 6 Sep (ErH) was a good find. Northern Shrike is a rare late fall and winter visitor to the region. Most visiting individuals stay farther north on the Navajo tribal lands and usually not as far south as the White Mtns. region. One shrike was discovered at Becker L. WA in Springerville 27 Nov (ErH, ElH).

Typical residents of pinyon-juniper woodlands in the region, Western Scrub-Jays seldom stray from their usual habitat. Odd sightings this fall were of this species in isolated tamarisk patches along Golf Course Rd. in Holbrook, with a family group of four birds 19 Sep (ErH, ElH) and one bird 13 Nov (ElH). Mexican Jays are rare to uncommon along the southern slope of the Rim in southern Navajo Co. and almost unheard of above the Rim. Therefore, it was amazing for three birds to be present in Heber 28 Oct (ElH). There are only two previous reports of this species in Heber, possibly the same individual tagging along with a Pinyon Jay flock seen in both 2000 and 2003 (fide ElH). There was also a Clark's Nutcracker in an Eagar yard 8-30 Nov (GC, DRo).

Although a common resident of higher elevation mixed conifer forests in the region, Red-breasted Nuthatches occur in lowlands during irruption years. This fall, evidence of at least some movement came from reports of these nuthatches from the following locations: one bird at Golf Course Rd. WP in Holbrook 4 Sep (ErH et al.) and 19 Sep (ErH, ElH), one bird at Pintail L. in Show Low 11 Sep (JSab), two birds in a Heber yard 15 Sep through 2 Oct and one bird 28 Nov (ElH), and one bird at Petrified Forest NP 15 Sep (JM). Another interesting Red-breasted Nuthatch sighting was of one at Granville CG in central Greenlee Co. 20 Aug (ErH, ElH). Although breeding was documented in Greenlee Co., this bird was farther south in the county and at a lower elevation (6600 ft.) than birds documented during the Atlas surveys. It is uncertain if this bird was part of a breeding population in that area or an early signal of the moderate movement that was seen in lower elevations elsewhere in the state.

One Swainson’s Thrush, which is considered a rare to uncommon transient through the region, was found near Black Canyon L. 6 Sep (ErH). A rare migrant through lowlands in the region, a Gray Catbird 29 Oct to 5 Nov at Petrified Forest NP was an excellent find (KBa). Phainopepla is a sparse resident of the Colorado Plateau, so one at Petrified Forest NP 17 Aug (KBa) and another in Holbrook 26 Aug (ErH) were noteworthy. In the White Mtns., this species tends to inhabit areas with high Phoradendron mistletoe densities, such as in habitats with cottonwoods or junipers.

American Redstarts are a rare migrant and former breeder in the region. One was discovered at Sipe White Mtn. WA 22 Aug (GC, DRo) and reported again 7 Sep (SH). Painted Redstarts are common breeders below the Rim, but rare postbreeding visitors above the Rim. One bird was found 22 Aug near Black Canyon L. (ErH et al.), and four birds were present in a mixed flock in Black Canyon near Baca Meadow 6 Sep (ErH et al.). Common Yellowthroats are an uncommon breeder and migrant in the region, but are rarer at the tail-end of fall. One at Wenima WA 27 Nov was unexpected (ErH et al.). A Northern Waterthrushes, rare migrants through the region, were found twice this fall with one at Petrified Forest NP 31 Aug (KBa) and another at Sipe 7 Sep (GC, DRo).

Fox Sparrows are a rare migrant in the White Mtns., with the ‘Red’ (iliaca or zaboria) subspecies being rarer than the expected ‘Slate-colored’ (schistacea) subspecies. A possible ‘Red’ Fox Sparrow was discovered along Cottonwood Wash n. of Clay Springs 25 Nov (ElH). White-throated Sparrows are a rare fall migrant in the region with previous reports from Holbrook. Two birds were present there near the HCGC 13 Nov (ErH, ElH). One bird was of the ‘white-striped’ subspecies, whereas the other bird was either an immature or of the ‘tan-striped’ race.

Dickcissel is a rare early fall migrant in the region, with fewer records for Navajo Co. than Apache Co. In s. Navajo Co., one bird in a tamarisk thicket along Golf Course Rd. WTP in Holbrook 19 Sep was a great find (ErH, ElH). A male Rose-breasted X Black-headed Grosbeak intergrade was an interesting find at Petrified Forest NP 21 Sep (KBa). Indigo Bunting is an uncommon migrant and local breeder in the region. One was found in Linden 19 Aug (GW, EWe). A common resident of the White Mtns., Pine Siskin flocks occasionally become large in the fall and winter across the region as shown by a count of 120 in Heber 25 Nov (ElH).

A high count of six blue morph Snow Geese were at Cibola NWR 25 Nov (PL, BC), and a new record high of 50 Ross’s Geese at Cibola NWR 25 Nov (PL, BC) surpasses the previous high count of 20 published by Rosenberg et. al. in The Birds of the Lower Colorado River Valley. A Cackling Goose, a casual species, was among 300 Canada Geese at Cibola NWR 25 Nov (PL, BC). An unusually high number of 42 Tundra Swans were counted during a water survey on Cibola NWR (S. Rimer). According to Rosenberg et al., 53 is the previous high count. Hooded Merganser used to be rare in our area, but has become fairly common over the past few years. A larger-than-usual group of 13 were spotted at Cocopah RV Resort a few miles northwest of Yuma 14 Nov (HD, SDe).

A vagrant Brown Booby was photographed at Meers Point, Imperial NWR, 10 Aug (G. Froelich). Brown Pelicans, particularly juveniles, are seen every year in late summer and fall. It was more unusual that four at Alamo L. 11 Nov (DM) included two adults.

High counts of 300 White-faced Ibis at Cibola NWR and 300 Cattle Egrets south of Parker 25 Nov (PL, BC) reflect how these birds are becoming more common in fall and winter. A White-tailed Kite was reported from north of Ehrenberg in the southern end of Parker Valley 22 Nov (LHar, DVP).

A rare Black-bellied Plover was spotted at Imperial NWR 7 Aug (A. Lamoreaux). An uncommon fall transient, Baird’s Sandpipers are not found in large concentrations in this region. Twelve at Vicksburg 21 Sep (MSt, DSt) was a larger-than-usual group.

A juv. Broad-billed Hummingbird first visited a hummingbird feeder in Yuma 19 Oct (HD, SDe) and continued through the fall season. An uncommon wintering White-winged Dove was seen nine miles northeast of Wellton 27 Nov+ (PL, m. ob.). A casual Yellow-bellied Sapsucker was south of Parker, near Poston, 26 Nov (PL, BC).

A casual Eastern Phoebe was seen nine miles northeast of Wellton 27 Nov+ (PL, m. ob.). The rare Thick-billed Kingbird returned for the ninth year to the Yuma Main Drain and was first spotted this year 14 Nov (HD). A vagrant Tropical Kingbird was found at the Aztec Feedlot 3 Oct (KR, CR).

Casually reported during migration, a Gray Vireo was spotted along the Gila R. seven miles east of Yuma 11 Sep (J. King). Rare for the Gila Valley was a Curve-billed Thrasher northeast of Wellton 27 Nov (PL, BC). Rarely seen in fall, a Swainson's Thrush at Imperial Dam/Hidden Shores 28 Sep (ph. G. Graves) was a good find. A casual Varied Thrush was photographed on the lawn of the Yuma Area Office, Bureau of Reclamation 10 Nov (HD). A late Black-throated Gray Warbler was at Parker 26 Nov (PL). A vagrant (but annual) American Redstart was located on the 'Ahakhav Tribal Preserve from 21-24 Sept (DSt, MSt). At the same location and date was an apparent Mourning X MacGillivray's Warbler 21 Sep (ph. DSt). Dickcissels staged a westward incursion into Arizona and California this fall. Two were spotted in Yuma Co.: one at Dateland 3 Oct (KR) and the other at Hidden Shores RV Park 28 Sep (G. Graves).

A vagrant juv. Streak-backed Oriole was videotaped nine miles northeast of Wellton 27 Nov (PL, BC). A second juvenile oriole was observed the next day (HD) and subsequently identified 4 Dec (PL) as a Streak-backed. The orioles were seen through the end of the reporting period (ph. ACo, m. ob.). A Painted Bunting, a casual transient in sw. Arizona, was spotted at Dateland 27 Sep (RW).

The monsoon season started out strong in July, but tapered off to below-average rainfall in August and September. Then in October, which is often a dry month, the region got a good rainfall. Summer was reluctant to let go and the daily high temperatures remained over 100° F. well into October. The juniper and berry crop up north was looking good for winter, so there wasn't much of any influx of higher elevation frugivores into the lowlands this fall.

There were very few goose reports, with most not arriving until later in the season as expected. A Greater White-fronted Goose was in a flooded field at Paloma Ranch 3 Oct (CR, KR) and another that has been resident in Ahwatukee continued through the period (PD). A male Eurasian Wigeon was found at the GRP 27 Nov (ph. TDeB) and a possible female was in the wigeon flock at the Paradise Cemetery 22 Nov (KR). A great find was an adult male Black Scoter at the GRP 14-17 Nov (BWa, ph. J. Ritz, JBu). This is the rarest of the three species of scoters in Arizona with most previous records pertaining to female-plumaged birds. There are fewer than five records for the region. Red-breasted Merganser, rare in the region, was reported at two locations: one at GRP 8-19 Nov (LHar et al.) and three at Gila Bend power plant 25 Nov (MHe). Away from the lower Colorado R., Common Loons are rare but regular fall migrants and are always noteworthy. One was on Tempe Town L. 30 Oct (JBu), one was on a pond in Mesa 30 Oct (DPe), and two were on Canyon L. 4 Nov (LHar, DVP). Three loon (sp.) were reported from the Estrella Ranch L. 7 Nov (MHe). Horned Grebes are also rare but regular migrants so one at the GRP 17 Oct-15 Nov (RWz, CBab), two there 19 Nov (KB), and another at L. Pleasant 17 Nov (ph. TDeB) was a good fall showing. Accidental in the region, a distressed juv. Brown Booby was discovered wandering around a parking lot at the Rio Salado Habitat Restoration site in Phoenix 30 Aug (CPk). Unfortunately it had enough energy to fly to a nearby busy roadway where it was struck by a vehicle and critically injured. The booby is now a specimen at the University of Arizona. Brown Pelicans, mostly young birds, wandered into the region and some lingered until the end of the period. There was one along the Gila R. in Goodyear 15 Aug (TC), one on Tempe Town L. most of the period (JBu), three on L. Pleasant 11 Nov (AOK), and an adult that moved up and down the Indian Bend Greenbelt in Scottsdale, where it was often seen at McCormick Ranch from 2 Oct until 24 Nov (BIs, m. ob.).

Casual to rare visitors, two Tricolored Herons were reported: one along the Gila R. in Goodyear, where it stayed 14 Aug-22 Sep (ph. ST et al.), and an immature at Paloma Ranch 3 Sep (ph. BGro). A juv. Reddish Egret was sighted just north of I-8 at Painted Rock Dam Rd. 16 Oct (ph. CR, KR) and again 21 Oct (SCa). Glossy Ibis is a recent addition to the state list and seems to be increasing. One was reported from the Paloma Ranch area 15 Aug (TC, KR). Roseate Spoonbill is casual in fall and one was found at the GRP 19-21 Nov (L & KB; ph. DVP, JRz). It disappeared from that location but was found later on private property. Northern Goshawk is casual in the lowlands so a sighting of a juvenile was noteworthy at the GRD (TDeB, JKo). There was a single report of a continuing Red-shouldered Hawk at HRP 6 Nov (DVP). A big surprise was a juv. Broad-winged Hawk inadvertently netted at HRP 19 Oct (C. Smith, B. Thompson, ph. S. Smith). Gray Hawks have been a recent addition to the HRP and one there 11 Oct (PD) was getting on the late side. A Zone-tailed Hawk, casual in the lowlands and in the region in November, was soaring over Scottsdale 11 Nov+ where one has wintered for the past few years (AS).

August and the first part of September are the peak diversity period for fall shorebirds and most of the regular occurring species were found. The GRP remains one of the best shorebird locations along with the dairy sludge ponds west of Phoenix and the Gila Bend area. A Black-bellied Plover, rare transient in the region, was reported from Paloma Ranch 14 Nov (HD). The number of reports of Snowy Plovers has declined during the past few years. It was good to have several migrants reported from the Gila Bend area 15-29 Aug (TC, KR, et al.). Black-necked Stilts congregated at GRP in large numbers, with nearly 770 there 22 Sep (ACo). Two Sanderlings, rare transients, were at the GRP 7-17 Sep (TDeB), and another one was at the Ocotillo Ponds, Chandler 14 Oct (LL). A Semipalmated Sandpiper was at a dairy sludge pond 15 Aug (TC) and two were at GRP on the same day (TC). One was also at the GRP 20 Aug CBab). The AZFO Shorebird ID Workshop 28 Aug located an impressive total of 20 species of shorebirds, including Semipalmated Sandpiper, Solitary Sandpiper, Baird’s Sandpiper, Pectoral Sandpiper, Short-billed Dowitcher, Stilt Sandpiper, and a Whimbrel (TC, KR ph. LL). The latter was at the dairy sludge ponds at Broadway Rd. and 195th Ave. A total of 13 Dunlins, a rare fall migrant and winter resident, were seen between 16 Oct and 22 Nov. The largest group of seven was reported from GRP 19 Nov (DVP, LHar).

Other than Ring-billed Gulls, all other gull species are noteworthy here in the desert. At the right time of year Sabine’s Gulls can be found. There was an adult on Saguaro L. 10 Sep (TDeB), a juvenile at GRP 13 Sep-23 (TDeB), one 22 Sep at Tres Rios (TDeB), one over Mesa 28 Sep (JMil), and one at Paloma Ranch 3 Oct (CR, ph. KR). There was a sprinkling of Bonaparte’s Gulls with one at the Gila Bend Sewage Ponds 30 Oct (CBab), another 17 Nov at the GRP (TDeB), and one along Painted Rock Rd. 25 Nov (MHe). Herring Gull is a rare but regular late fall transient and a juv. bird was at the GRP 8 Nov (DVP, TDeB, LHar). In general Least Tern observations seem to be on the increase in Arizona, but there was only one sighting this fall in the region with an individual at the GRP 20 Aug (TDeB, JKo, CBab). Caspian Terns are uncommon transients, but one at the Tres Rios Wetlands 15 Oct (MHe) was on the late side. A Black Tern, also an uncommon fall transient, was very late at the GWR 25 Oct (RDi).

The only two Ruddy Ground-Doves noted this fall were two at GWR 31 Oct+ (ph. PMo). An Elf Owl put in a late appearance in south Scottsdale on its way south 10 Sep (AS). Broad-billed Hummingbird is a rare but increasing visitor to the region and one was at the BBRA 7 Oct (TDeB, JKo). Broad-tailed Hummingbird is uncommon in the lowlands, and a very late subadult male according to photos in Dec was at the GWR 29 Nov+ (JKo). The female Green Kingfisher reappeared at the HRP 6 Nov (CSm). It is thought that it had moved downstream to an area near the closed rest area and its reappearance coincided with the reopening of the rest area. An Acorn Woodpecker, rare in the lowlands, was in a residential area of east Mesa 11 Sep (JTA). A male Yellow-bellied Sapsucker, rare in fall and winter, was at the BTA 30 Oct (JJ). Northern Beardless-Tyrannulets are scarce in the region and a late bird was at the BTA 12 Nov (CT). A late Willow Flycatcher was at MCW 26 Sep and 3 Oct (TC). Say’s Phoebes are usually not of note but a pair with three recently hatched nestlings in north Phoenix on the late date of 4 Nov (P&GH) was quite unusual. This is over a month later than any nesting record ever reported in Arizona and could be a record late nesting date for the species in the United States. Brought to wildlife rehabbers, all three young were ready for release in early December. One of the best finds of the season was of several Dusky-capped Flycatchers in the Slate Cr. area of Maricopa Co. 9 Aug (TDeB). There are only a handful of county records. Another visit to the area 15 Aug (TDeB, JKo) documented successful nesting had likely taken place. Casual fall visitors, with most records in September, an Eastern Kingbird was near the Gila Bend Power Plant 8 Sep (ph. MSt, MPo), and another one or possibly the same bird was about six miles west on Powerline Road 14 Sep (ph. TDeB, JKo). A late Bell’s Vireo was at the BTA 6-12 Nov (TC). There was an early influx of Red-breasted Nuthatches into the lowlands where it is irregularly detected, but they didn’t seem to remain into the late fall and winter. The MCW produced at least eight, with the first two noted 26 Sep and the last one 12 Nov (TC).

Since the recent split of Winter Wren into Pacific Wren and (eastern) Winter Wren there have been many interesting reports in this region. A Winter Wren was detected by call at the MCW 12 Nov (TC) and was found again 14 Nov (LHar, DVP). Irregularly reported in the desert lowlands, a Townsend’s Solitaire was at the BBRA 31 Oct (BIs). The BTA is a good place to search for Rufous-backed Robin given its history of sightings there, and one was found 20-27 Nov (TC, ph. RDi). Casual visitors to the region, a Varied Thrush was at the MCW 11 Oct (TC) and another was in a residential yard in nw. Phoenix 6 Nov (ph. MScr). Gray Catbirds nest very locally in the White Mtns. of Arizona and are rare as migrants elsewhere in the state. A Gray Catbird was identified at the BTA 24 Oct-6 Nov (ph. BGri, m. ob.) but may have been present as early as 9 Oct. A Brown Thrasher at the Desert Botanical Garden, Phoenix 16 Nov+ (DHe et al.) was a casual visitor. Sprague’s Pipit is a rare winter visitor to the region and seems to be declining throughout its range. One was on the Rousseau Sod Farm near Scottsdale 7 Nov (TDeB; ph. DVP) where it remained easy to find at least through 10 Nov. Chestnut-collared Longspurs are a fairly common transient, McCown’s is uncommon in the state but casual in Maricopa Co., and Lapland is casual with only about 15 records in the state. All three species were found together at the Rousseau Sod Farm near Scottsdale 6 Nov; one McCown’s, two Lapland, and about 20-30 Chestnut-collared Longspurs were seen on the sod (ph. JaMc, RMe). The number of McCowns increased to a regional record high of 17 by 9 Nov (TDeB, DVP), with at least four remaining through 17 Nov.

Finding an "eastern" warbler is often a highlight of the season and there were many highlights this year. A male Northern Parula was at the GWR 22-26 Nov (ph. CSt). A Chestnut-sided Warbler was reported at Tolleson 20 Nov (ph. BGro) and another was found in the BBRA 22 Nov (JHol). Both species are considered rare but regular migrants. Casual fall visitors to the region, a male Black-throated Blue Warbler delighted many birders at the BTA 24-27 Oct (ph. LLan). A fall female Blackburnian Warbler was a great find at the MCW 11 Sept (ph. TC). A Palm Warbler along lower Indian Bend Wash was near Tempe Town L. 24-28 Oct (MTo) where it was photographed 26 Oct (BGRi). Another rare but regular migrant, there were three Black-and-white Warblers noted: one at Goldfield along the Salt R. 10 Sep (TDeB), one at the GRD 30 Sep (SG), and one at the BBRA 31 Oct (BIs). Three American Redstarts were found: singles at the MCW 11 Sep and 3 Oct (TC) and one at GRD 26 Sep (MWa). Reports of Prothonotary Warblers have increased to being almost annual in the region. Two were found this season with one at the GWR 19 Sep (NK) and another one at the MCW 26 Sep (TC, TDeB). There were two casually reported Worm-eating Warblers this fall with one at the MCW on the early date of 20 Aug (TC) and one at the BTA 25-29 Oct (ph. JHol, m. obs.). One of our more regular, but rare migrants, five Northern Waterthrushes were discovered this fall, all within a seven-day period: 31 Aug along Sycamore Cr. (TC, JRen), one at the GWR 5 Sep (DPe), two along Queen Cr. near the BTA 5 Sep (JBa), and another in Scottsdale 6 Sep (JBa). There are very few records for Kentucky Warbler in the region so a second-year male banded at the HRP 14 Aug (ALe, CSm, ph. CB) was an excellent find. A Wilson’s Warbler at Rio Salado 19 Nov (LHar, DVP) was a late migrant or attempting to winter.

Casual to rare in the region, a Grasshopper Sparrow was a good yard bird in Mesa 29 Oct (ph. JMil). A casual transient Clay-colored Sparrow was reported from GWR 22 Sep (SG). Pyrrhuloxias are uncommon and very local breeders in the northwest and southern edges of the region so two sightings, one of a male in Carefree 7 Nov (TC) and another in Papago Park 14 Nov (JBu) away from these areas were noteworthy. A Dickcissel in Wittman 29 Sep (ph. CSm) was one of a relatively large number found in the state this fall.

Gila

Above average late monsoon rain fell throughout August in parts of Gila Co., although the remainder of the fall period was much drier. Roosevelt L. was 89% full on 22 Nov, whereas San Carlos L. dropped to 11% after being 30% full in May.

Four Red-breasted Mergansers, casual to rare transients, were reported at Roosevelt L. 6 Nov (DP). Rare away from the Colorado R., a single Common Loon was reported at the Orange Peel Recreation Area at Roosevelt L. 31 Oct (ErH, ElH). Rare to uncommon transients in fall, sometimes seen in large flocks, more than 50 American White Pelicans were at San Carlos L. 31 Oct (DJ, JSab). Several hundred Aechmophorous grebes, mostly Western, were at San Carlos L. 31 Oct (DJ, JSab), and some 100+ were at Roosevelt L. 31 Oct (ErH, ElH).

An uncommon resident of lakes and rivers, rare or casual July to 15 Sep, one Bald Eagle was seen at San Carlos L., where it is known to breed, 8 Sep (JM). Harris's Hawk is a generally uncommon but locally common resident in well-vegetated Lower Sonoran Desert areas and its range has been steadily increasing since the mid-1970s. There have been few reports of Harris's Hawks in Gila Co. though, so a pair seen at Jake’s Corner was a great find 31 Oct (ErH, ElH). The species was not found nesting in the county during the Atlas surveys.

Magnificent Hummingbird is a probable very local breeder along the Mogollon Rim although nesting has not been confirmed in the region. Regular sightings of this species continue in n. Gila Co. Two adult females were notable at the Tonto Cr. Fish Hatchery feeders 3 and 19 Aug (ErH, BHo, ElH).

Rarely seen away from its normal Lower Sonoran Zone habitat, a single female Gila Woodpecker was an unexpected visitor to a suet feeder in a Pine yard 25 Nov + (JE). This may be the first report of this species in Pine. The location is just below the Mogollon Rim in pinyon-juniper-ponderosa habitat at 5800 ft.

A Pacific Wren was a good find at Horton Springs in n. Gila Co. 26 Nov (ph. ErH, ElH). Rare in fall to Lower and Upper Sonoran Zones, it is unclear if this individual was a local breeder from the Rim area or a wintering migrant. Pacific Wren has been confirmed during Atlas surveys to be nesting in small numbers in the See Canyon area north of Christopher Cr. in n. Gila Co. However, this shy, skulking wren may be more widely distributed, including in moist, shady drainages along the Mogollon Rim, where it can be hard to detect (Atlas).

Possibly declining even as a fall and winter visitor in Gila Co., a single American Dipper was seen at Fossil Cr. 25 Oct (RF), where they have been reported in the past. The bird was seen around a large 18-foot waterfall at the end of the trail about a mile east of the Flume Trailhead. American Dipper prefers fast-flowing streams, so the recent removal of the Fossil Cr. S.R.P. Dam, restoring creek flows, could make this habitat more favorable.

Olive Warblers are fairly common summer residents above the Mogollon Rim, and at least part of the population migrates south of Arizona for the winter. A rare resident below the Rim in Transition Zone pines in late fall and winter, three Olive Warblers was a high number seen with a mixed species flock at Bottle Spring off the Young Rd. 23 Nov (ErH, ElH, BHo). Rare but regular transient in late August and September, a Northern Waterthrush was noteworthy at Windy Point Campground, Roosevelt L. 8 Sep (JM).

There have been rare reports of Dark-eyed Juncos having whitish plumage characteristics in at least two forms: Slate-colored in e. states and Oregon in the West. A white eye-ring Oregon Junco variant was a surprise at Jake’s Corner 6 Nov (BIs). Tanagers were reported later in the fall than usual, including two Hepatic Tanagers in the Pine area 16 Oct (BIs).

“Draw a line from Nogales to Safford, if you were northwest of that line, you got little rain” from the monsoon as of mid-August-- Erik Pytlack of the National Weather Service Tucson Office.

Rainfall totals did not improve much from there as the monsoon wound down. Overall, the NWS reported this as the 15th warmest and 21st driest fall on record in Tucson. This included the fourth warmest August and second warmest September on record, with 16 days in September reaching 100 or more degrees tying the record for the month. October was the 21st warmest and the first 20 days of November continued with temperatures much above normal only to end with 11 days of much below normal temperatures. The first freezing day of the entire year in Tucson (dating back to before January 2010) came on November 26, the second latest date ever (with the third latest being a February date).

This report mentions many individual birds that were present on late dates. Whether the relative plethora of birds found in date ranges considered “casual” reflects an increase in their occurrence in the region or just a broadening of the reporting base in the age of rapid and widespread electronic communication is unknowable, but the latter explanation likely accounts for some portion of the increase.

Riparian habitat along the Santa Cruz River from Tumacacori north to Tubac provided many interesting reports. Although there was not the great diversity of warblers species found last fall, there were still plenty of the regular rarities found along with some of the rarer rarities. One of the highlights of the season was the successful nesting of Least Grebes at Peña Blanca L. The splitting of the Winter Wren into two species in North America was followed by reports of good numbers of the “new” Winter Wren and one report of Pacific Wren this season, an inversion of the old, perceived pattern of occurrence in Arizona. More exciting was a Sedge Wren found and photographed at Peña Blanca L., which, pending acceptance by the ABC, will be the first record for Arizona.

An adult Greater White-fronted Goose at Lakeside Park, Tucson 19 Aug+ (MSt) was the earliest ever in the region by about a week. Among the 90 others reported during the migration period, the highlights were a flock of 55 over Tucson 2 Sep (JY) and 15 over Sweetwater 18 Sep (MPo, MSt). The first Snow Goose of the season was at Whitewater 19 Oct+ (LEp) when rare. Away from Whitewater, single Snow Geese were at Lakeside Park 5-11 Nov (S. Goldwasser) and Sierra Vista EOP 14 Nov (D. Nagle et al.). The first Ross’s Goose was reported at Willcox 9-18 Nov (DT), an unremarkable date. The only one reported away from the Sulfur Springs Valley was at Amado STP. 19 Nov (JH). Canada Goose is remarkably uncommon in the region, and one at Kennedy Park, Tucson 8 Oct+ (JH) was notable for being the only one reported. It was small and appeared to be of the parvipes subspecies. Tundra Swan is a rare transient; the only report was of six at Whitewater 26 Nov (SW). Up to four Gadwalls were at Sierra Vista EOP 1 Aug+ (EW et al.), when rare. The “Mexican Duck” form of Mallard has been relatively neglected by observers since it was demoted from full species status and it has intergraded widely with typical Mallards, so its distribution is less clear than in the past. At least one drake appearing to be “pure” was at Thatcher STP 17 Aug (DSt), where it isn't typically reported. Observers may want to give the “Mexican Duck” increased attention as the AOU is considering elevating it to species status again. The Northern Pintail found at Sweetwater in July continued until 20 Aug (m. ob.). The first Canvasback of the season was reported 27 Sep (G. Graves) at Sweetwater when rare. The female Greater Scaup that summered at Willcox was last reported 1 Oct (m. ob.). Hooded Mergansers put in a good showing with up to 15 reported 31 Oct+, 10 of them at Sam Lena Park, Tucson 29 Nov (m. ob.). A Common Merganser at Parker Canyon L. on the unseasonal date of 22 Aug (B. Sullivan et al.) appeared to have an injured wing and had likely been present for some time at this under birded location. Red-breasted is the rarest merganser in the region; four were at Willcox 6 Nov (ph. HHa), a typical passage date. At Sweetwater, Ruddy Ducks had several late broods; dependent young were observed, including eight 1 Oct (JBoc et al.) and another five and eight 11 Oct (MSt).

Pacific Loon is a casual transient in the region so one (and reportedly two) at Patagonia L. 26 Oct+ (ph. SH) was of note. Rare in the region, a Common Loon at Patagonia L. 26 Oct+ (SH) was joined by a second Common Loon 28 Oct+ (ph. ASc). In Tucson, a Common Loon was at Sam Lena Park 9-21 Nov (N. Briefer). The saga of the Least Grebes at Peña Blanca L. continued from the summer season with two adults reported through 13 Aug followed by a hiatus in reports until 29 Oct when a single adult was seen (CCa) and 2 Nov when one adult and four striped juveniles were seen (ph. ASc) (eventually both adults were seen again). Not since 1964 had there been indications of breeding by this species in Arizona, and this (including the failed nest from the summer season) becomes the most certain instance of nesting known in Arizona. Of note is that the likely breeding recorded in 1964 was on the nearby west side of the Tumacacori Mtns. (SeL). Early southbound Eared Grebes were at Benson STP 29 Aug (JY) and Ajo STP 8 Sep (TSt). Nine Western Grebes were reported in the region beginning 8 Oct while Clark’s Grebe went unreported. Numbers of Brown Pelicans were remarkable for their paucity until late in the fall. The pelican present at Patagonia L. since spring was last reported 22 Aug (m. ob.) and one touched down briefly in Rio Rico 9 Aug (MBi). Another was reported at Patagonia L. 9 Nov (LEp). Then, associated with a strong south-southwest wind event, an amazing dozen were found together on Amado STP 21 Nov (ph. J. Michael), dwindling to three the next day. Singles were subsequently seen at Lakeside Park 24-25 Nov (MPo), Rio Rico 25 Nov (ph. courtesy J. Wetzel), and Sahuarita L. 26 Nov (M. Deming), possibly dispersers from the Amado dozen.

A rare fall and winter visitor, an American Bittern was at the favored location of Patagonia L. 22 Oct-26 Nov (I. Field, J. Broz). Late Snowy Egrets were a single at Sam Lena Park 23-29 Nov (JH) and three at Sweetwater 24 Nov (RHo). Tricolored Heron is a casual visitor from the south. One at Lakeside Park 22 Sep-11 Oct (DW; ph. DSt) was reportedly tangled in fishing line before it departed. One at Sam Lena Park 6 Oct (JSab) was not refound. Finally, one with an injured leg, possibly the bird from Lakeside Park, was in ne. Tucson 16 Oct-7 Nov (BN) during which time it regained a normal gait. Black Vultures are very rare in Cochise Co. and are usually localized to the border area so two at the Douglas golf course 21 Aug (B. Sullivan et al.) were of note. Two Black Vultures on the eastern foothills of the Tucson Mtns. 7 Sep (SeL) were the first the observer had seen there since the late 1950s when roadside carrion removal by the county became common there. A Turkey Vulture was late at the Avra Valley STP 25 Nov (JH). Osprey had been considered to be “casual” in the region after the end of October, but recent years have seen that status increase to “rare” through the fall; up to six total were reported during November, with the latest report on 27 Nov. A Mississippi Kite that strayed to Rio Rico 4 Aug (CCa et al.) was likely a postbreeding wanderer. The first report of Northern Harrier came from Willcox 13 Aug (SH) when considered “rare”. The intermittently reported Common Black-Hawk at Rose Canyon L. was last reported 8 Aug (m. ob.). This species is considered “casual” in the region after mid-October but there were four reported 18-23 Oct as the last migrants departed. Gray Hawk is slowly expanding its range in Arizona. Individuals away from long-established nesting areas included singles at Sahuarita in August (BPo et al.), Hot Well Dunes north of Bowie 9 Sep (DSt), and along Klondyke Rd. near Rattlesnake Rd., Graham Co. 16 Sep (DSt). Like several other raptors, this species has also been lingering later into the fall in the region: nine were reported 8-20 Oct. Likely getting set to winter again, a Gray Hawk was at Amado 5 Nov+ (B. Brown). The Short-tailed Hawk returned to e. Tucson to winter again 28 Oct+ (J. Notestine) and was first noted in the usual Seneca/Ridgeway neighborhood 11 Nov+ (DSt). It continues to sport atypical plumage, sparking a debate between the possibility of erythristic plumage and hybrid parentage (see a discussion along with the photos at azfo.org). The only report of Rough-legged Hawk came from Kansas Settlement 15 Nov (FK). In the Santa Cruz Flats, reported numbers of Crested Caracaras were lower than in recent falls, with one seen 18 Sep (CK) and three reported 11-24 Nov (DT et al.).

Though not unexpected, Sandhill Cranes are seldom reported from the Gila R. valley at Duncan, so 21 there 31 Oct (D. Hileman) was of interest. The only report of Snowy Plover in the region consisted of one at Willcox 29 Aug-16 Sep (JY et al.). The only reports of Mountain Plovers came from Evergreen Turf sod farm in the Santa Cruz Flats where up to 40 were reported 26 Nov+ (CK). Whether the lack of reports of Mountain Plovers from the Sulphur Springs Valley resulted from changed crop choices due to market factors, lack of observer effort, lack of plovers or other factor(s) is uncertain. An American Avocet was “casual” late at Willcox 10 Nov (SH) as were 10 at Kennedy Park 25 Nov (JH). An Upland Sandpiper reported at San Bernardino NWR 21 Aug (RWe) would make only a fourth record for the region. A Marbled Godwit at Thatcher 17 Aug (DSt) was notable in Graham Co. Among the rare but regular shorebirds reported were two Sanderlings, four Semipalmated Sandpipers (all at Willcox), three Dunlins, and a paltry two Short-billed Dowitchers, all on typical dates excepting one Dunlin early at Ajo STP 26 Aug (TSt). The season’s first report of Wilson’s Snipe came from Sierra Vista EOP 29 Aug (EW) when rare. Late “casual” Wilson’s Phalaropes were singles at Willcox 19 Oct (SH) and Green Valley STP 28 Oct (B. Brown). Casual at any season, but less so in fall, a Red Phalarope was at Bog Hole WA 15 Sep (ph. ASc). Franklin’s Gull is a rare but regular fall migrant. Outliers included early individuals at Amado STP 19 Sep (JMc), Willcox 1 Oct (SH) and Mammoth STP 6 Oct (R. Crossley). A total of 16 Bonaparte’s Gulls were reported 22-24 Nov, during the time frame when they are considered rare but regular. A Heermann’s Gull at Sweetwater 8 Nov (D. Ginter, B. Spahn; ph. ACo) followed the typical pattern of this species, which is “casual, less so in late fall, and does not stay long.” No Sabine’s Gulls were reported in the region this fall.

Ruddy Ground-Doves staged a bit of a comeback with six reported 16 Aug-28 Nov+. Less than annual, a Groove-billed Ani was a fine find at Whitewater 5 Nov (GLe; ph. ACo). Quite unexpected was the report of an Elf Owl that “barked steadily for almost a minute” at Tumamoc Hill, Tucson 5 Nov (MBr). There are only two established records of Elf Owl from later than mid-September in the region, one each in November and December. Long-eared Owl is an irregular visitor; singles were reported at Big Wash, Pinal Co. 20 Oct (DJ) and road killed in the San Rafael Valley 20 Nov (ASc). A casual visitor to the lowlands, a Northern Saw-whet Owl was at Tohono Chul Park, Tucson 4 Nov (ph. courtesy J. Falls). Lesser Nighthawk is “casual” after mid-October so six at Crossroads Park, Marana 18 Oct dwindling to two 1 Nov (ACo) were remarkable. Also late/”casual” were three Common Poorwills at Dragoon Mountain Ranch 24 Oct (ARi). Vaux’s Swift numbers were closer to (or even below) the norm this fall than last. Interesting reports from the southeast portion of the region included four at Portal 22 Sep (NMC) and one at Whitewater 31 Oct (SH). This species becomes progressively rarer to the east and south toward New Mexico.

Seldom seen at high elevations, an adult male Broad-billed Hummingbird was banded at over 9,000 ft. on Mt. Lemmon 8 Aug (EF). White-eared Hummingbirds departed the Beatty’s in Miller Canyon, Huachuca Mtns. by 7 Oct (TBE) and a feeder in Portal by 31 Aug (RWe). Another White-eared was banded at the Chuparosa Inn, Madera Canyon 9 Aug (EF), where they have been almost regular in recent years. In the Chiricahua Mtns., a Berylline Hummingbird was again found nesting near Stewart Campground, Cave Creek Canyon 9-28 Aug (S. Kirn, ph. RWe). Another visited a Portal feeder 28 Aug-16 Sep (ph. RWe, RAR et al.). The last Berylline report of the season at Beatty’s came 24 Aug (TBE). Away from Sonoita Cr., Guadalupe Canyon and the east side of the Huachuca Mtns., Violet-crowned Hummingbirds are relatively uncommon. Of note this season were two to three continuing in Bisbee through at last 28 Sep (M. Turisk), two in French Joe Canyon 7 Aug (MCo), one at Jasper’s in Portal 11 Aug (B. Powers et al.), and 2 at another Portal feeder 16 Aug (MD). After August, migrant Violet-crowneds turn up at other locations. Up to four were in a Bisbee yard 12 Sep-16 Nov (SW), singles were at feeders near Three Points 3 Oct (ph. T. Holland), in the Mule Mtns. 22 Oct (K. Lamberton), in sw. Tucson 31 Oct+ (R. Watts), and in Green Valley 1 Nov+ (C. Trible). In the Huachucas, four were reported after 1 Sep. Blue-throated Hummingbird is seldom seen away from breeding habitat so two in Hereford 11-12 Oct (TBa), one at the Paton’s in Patagonia 28 Oct (MMa), and another at Green Valley 27 Nov+ (C. Trible) were notable. The hummer of the season for birders was the Plain-capped Starthroat that visited the Paton’s feeders 4-21 Sep (MMa, ph. ACo, CMe, CVC). The starthroat is less than annual in Arizona. Most Arizona reports of Lucifer Hummingbird in recent years have come from the Ash Canyon B&B on the east side of the Huachuca Mtns., where they were present through 26 Sep (MJB). Reports also came from lower Ramsey Canyon in Aug (J&MH), below Miller Canyon 14 Oct (TBa) and below Carr Canyon through the late date of 2 Nov (HBr). More than is typical were reported in migration away from the Huachucas: a male returned to Dragoon Mountain Ranch 24 Aug-10 Sep (ARi), one was in the lowlands at San Simon Cienega 8 Sep (RWe), up to two were along Banning Cr., Mule Mtns. 27 Sep-15 Oct (ph. K. Lamberton), in Bisbee 28 Sep (SW), at the Paton’s 21-27 Oct (MMa; ph. ASc), and in the lowlands at the San Pedro House 26 Oct (EW, ph. S. Elwell). Rarer than the starthroat, but less accommodating was a Ruby-throated Hummingbird visiting a Portal yard 29 Oct (ph. RWe) that would make a fourth Arizona record and a first for Cochise Co. Likely returning for its second winter, an apparent Black-chinned X Costa’s Hummingbird was in a Tucson yard 16 Oct (RHo). A Costa’s Hummingbird was a bit of a surprise in a Bisbee yard 16 Nov (SW) as they are not common in the area. A total of five Calliope Hummingbirds was reported 23 Sep-27 Oct, a period when they are considered “casual”. Likewise, four Broad-tailed Hummingbirds were reported 27 Oct-21 Nov. Not to be left out of “casual”, nine Rufous Hummingbirds were reported 21 Oct-1 Nov. The only Allen’s Hummingbird reported was a juv. male banded at W. Turkey Cr., Chiricahua Mtns. 18 Sep (S. Wethington).

An adult male Elegant Trogon at Patagonia L. SP 8 Nov+ (SH) is likely “the trogon” that has wintered there for multiple consecutive years. Surprising but sad was an Elegant Trogon found dead in a yard in lower Flux Canyon, Patagonia Mtns. 14 Nov (P. Gordon fide TA). The nearest known nesting area is to the west in the Santa Rita Mtns. Green Kingfisher remains a sparse and irregular visitor to the state, most often reported from the upper San Pedro R. Two and possibly three were at San Bernardino NWR 5-14 Aug (RWe) with one seen again 15 Sep+ (RWe). Williamson’s Sapsucker is regular in the mountains as a migrant and wintering species but is rare in the lowlands. Single males were at Peña Blanca L. 29 Oct (ph. ASc) and Evergreen Cemetery, Tucson 9 Nov+ (RHo). Yellow-bellied Sapsucker was reported in well above average numbers this season. Reports comprised an adult female at McCormick Park, Tucson 17 Oct (MSt), a juvenile along Blue Haven Rd., Patagonia 16 Nov+ (MBr; ph. ASc), a juvenile at Peña Blanca L. 27 Nov+ (ph. ACo et al.), a juvenile in Sabino Canyon in early Oct (WR), a juvenile in ne. Tucson in mid-Oct (WR) and a juvenile south of Sabino Canyon in early November (WR). Arizonans are used to seeing hybrids involving Red-breasted Sapsucker, but a Red-naped X Yellow-bellied Sapsucker in Portal 13 Oct (RWe) was more unusual. A Red-breasted Sapsucker in McCormick Park 17 Oct-4 Nov (MSt; ph. RT) was apparently the same bird that wintered there last year, though it apparently moved on and will not winter. Stunning was a well-described Downy Woodpecker working a cottonwood in the lowlands at San Bernardino NWR 24 Oct (RWe). Although this species is reported not infrequently in the region, few of the reports adequately separate the bird sighted from Ladder-backed or Hairy woodpeckers. The yellow-shafted form of Northern Flicker is casual in the region. Singles were reported in e. Tucson 24 Nov (R. Hartigan) and Huachuca Canyon 27 Nov (SH).

The Northern Beardless-Tyrannulet is rare in the Chiricahua Mtns. so one visiting a yard east of Portal on the relatively late date of 4 Sep (NMC) was of note. A Gray Flycatcher along the Santa Cruz R. s. of Carmen 13 Aug (DSt) was an early migrant. Rare but regular from mid-October to mid-March, five Eastern Phoebes were reported 17 Oct-20 Nov. “Rare” in the first half of October, three to four Dusky-capped Flycatchers were along the Santa Cruz R. s. of Carmen 12 Oct (DSt). Tropical Kingbird is an uncommon and localized nesting species in the region, with most departing by mid-September. Notable reports this season included one at Castle Rock Estates, Tucson 3 Aug (BN) where they have nested in the past, two fledglings at Sweetwater 24 Aug (m. ob.), and three late at HTM 21 Sep (EW). In the past, Cassin’s Kingbird was regarded as “casual” after mid-October but the many reports in recent years indicate this species is staying later in the fall in the region: this season 20 were reported in the first half of November and 27 in the second half of November. One Thick-billed Kingbird lingered to “casual” status, at Patagonia-Sonoita Creek Preserve 3 Oct (CCa). A Bell’s Vireo lingered at Tubac to 17 Oct (JSab). Blue-headed Vireo is one of the most challenging rare birds in Arizona because of the combination of its rarity and the potential for brightly plumaged Cassin’s Vireos to resemble them. A report of one at San Bernardino NWR 29 Sep (ph. RWe) will be evaluated by the ABC. A Warbling Vireo was late/”casual” at Tucson 27 Oct (CBen et al.).

Swallows have been reported lingering to “casual” dates in increasing numbers too. The season saw a Tree Swallow at Benson STP. 22 Nov (ARi) and up to four at Amado STP. 22-29 Nov (RF). Single Violet-green Swallows were at Sweetwater 21 Nov (SO) and Kennedy Park 23 Nov (JH). Single late Northern Rough-winged Swallows were at Sweetwater 21-23 Nov (SO) and Amado STP. 22 Nov (RF). Late Cliff Swallows were at McNeal 19 Oct (EW) and Willcox 20 Oct (RT). And finally, a single Barn Swallow was at Whitewater 21 Nov (EW). There was a scattering of Red-breasted Nuthatches irrupting to the lowlands, with about 10 reported 29 Sep-15 Nov. This was part of a larger movement of this species seen in multiple states this fall. In the wake of the official splitting of the former Winter Wren into two species in North America by the A.O.U., there were multiple reports in the region this fall. The “eastern form” Winter Wren was reported at San Bernardino NWR 24 Oct (s.r. RWe), in Humboldt Canyon, Patagonia Mtns. 30 Oct (ph. ASc), and along the Santa Cruz R. s. of Tubac 27 Nov (ph. CMc). The “western form” Pacific Wren was reported at Dudleyville 14 Nov (DJ). In the past, the “western form” was reported more commonly in Arizona. Was there a larger, unusual, movement of the “eastern form” in the western U.S. this fall or has their relative status really inverted? Voice remains the best trait with which to identify these species. The discovery of a Sedge Wren at Peña Blanca L. 27 Nov+ (ph. ASc) provided an exciting first adequately documented occurrence of this species in Arizona, although the bird has not been easy to relocate. Since there are multiple records of Sedge Wren in California, this was considered overdue here. A Marsh Wren at Willcox 13 Aug (SH) becomes the earliest recorded fall date in the region by two days. Rare in the lowlands, three Golden-crowned Kinglets were along the Santa Cruz R. at Tumacacori 6-7 Nov (MLe, CMc). A pair of Black-tailed Gnatcatchers was feeding young along Atturbury Wash, Tucson on the late date of 23 Sep (MPo). Though still present in multiple locations, Black-capped Gnatcatcher reports have diminished noticeably in the past year or more. Such variation is not unusual for a species at the edge of its range. Reports this season were few and included two at Montosa Canyon, Santa Rita Mtns. 28 Jul-1 Oct (m. ob., CCa), one at Brown Canyon, Baboquivari Mtns. 3 Aug (JM), two at Leslie Canyon NWR 7 Aug-30 Sep (B. Radke et al.), one at “Nutting’s Wash”, Patagonia L. SP 12 Sep (MB), two near the dam at Patagonia L. 27 Oct (RT et al.), and one at Proctor Rd. at the mouth of Madera Canyon 30 Oct (LHal).

A late migrant Swainson’s Thrush was at Roger Road STP., Tucson 19 Oct (MSt). A casual to rare fall and winter visitor to the region from Mexico, single Rufous-backed Robins were at McCormick Park 7 & 17 Nov (CG, ph. MGH; ph. KKe), Sonoita Cr. above Patagonia L. 18 Nov (ASc), and along the Santa Cruz R. n. of Tubac 26 Nov (MSt et al.). The handsome Varied Thrush is always a crowd pleaser; this season singles were at the Arizona-Sonora Desert Museum, Tucson 8-12 Nov (L. Harris, BBi; ph. JHa) and Santa Gertrudis Lane, Tumacacori 12 Nov (D. Fort, ph. DDu). A skulking Gray Catbird scarfed pyracantha berries at the Santa Rita Lodge, Madera Canyon 17-28 Nov (ph. S. Elwell). A Sage Thrasher was in the San Rafael Valley on the early/”casual” date of 27 Sep (ASc). A Brown Thrasher took up guarding a pyracantha bush in nw. Tucson 21 Oct+ (LN, L. Greene; ph. ACo), another was at “Dancing Turtle Tank” near Portal 2-5 Nov (D. Johnson), and a third was at Agua Caliente Park, Tucson 9-10 Nov (ph. RCa).

Although there is seemingly ample agricultural habitat for them, longspurs are seldom reported from the Santa Cruz Flats, so a single Chestnut-collared Longspur there 30 Oct (RF) was of note. Recent years have seen multiple occurrences of Tennessee Warbler at Sweetwater and this fall continued the trend. One was present there 17 Sep (WR; MLe) and another 28 Nov+ (MSt; ph. ACo). Nashville Warbler is casual in the region after mid-October so of note were singles at Tubac 13-29 Nov (CMc), Sweetwater 21 Nov+ (LN) and Peña Blanca L, 21 Nov (GW). A Virginia’s Warbler was late at Sweetwater 29 Sep-1 Oct (MSt, MPo) as was a Lucy’s Warbler there 21-29 Oct (MSt). Northern Parula is a rare but regular migrant in the region; seven were reported 8 Oct-25 Nov. Apparently in place for a second consecutive winter, a Yellow Warbler chipped loudly and persistently near the bridge at Sweetwater 10 Oct+ (MSt). Late but not lingering were Yellow Warblers at Roger Road STP. 22 Oct (RT) and Tubac 29 Nov (MB). Nearly annual in the region, single Chestnut-sided Warblers were at Continental Reserve, Marana 20 Oct (ph. M. Jones) and along the Santa Cruz R. n. of Santa Gertrudis Lane 31 Oct-7 Nov (WR; ph. LHal). Less than annual, a Magnolia Warbler was at Roger Road STP. 4-8 Oct (MSt; ph. ACo, DSt). Black-throated Blue Warbler is a casual fall transient; singles were at Hereford 19-23 Oct (ph. RB) and the Arizona-Sonora Desert Museum 10-15 Nov (K. Duffek; ph. D. Austin). More casual than most, a Black-throated Green Warbler was along the Santa Cruz R. s. of Tubac 20-27 Nov (ph. CMc, MLe). A late Hermit Warbler was at Roger Road STP. 7-29 Oct (JHa). A casual transient, a Palm Warbler was in lower Miller Canyon 19-23 Nov (CVC; ph. CMe). Black-and-White Warblers put in a good showing, with nine reported 7 Aug-28 Oct, with one continuing at Sweetwater into winter. American Redstart was less numerous than that, with five found 21 Aug-7 Nov. The other common “rare” warbler, Northern Waterthrush, presented at least 16 individuals for viewing 25 Aug-26 Sep. Highlights included 3 on a single visit at San Simon Cienega (RWe) and one at Hot Well Dunes (DSt). A male Hooded Warbler was found along the Portal-Paradise Rd. 21 Aug (B. Sullivan et al.) and a female was along the Santa Cruz R. n. of Santa Gertrudis Lane 31 Oct+ (WR; ph. DD). The latest Wilson’s Warbler was at Peña Blanca L. 29 Nov+ (LHal). A few Painted Redstarts ventured out of habitat in passage or to winter. Singles were in Oro Valley 14 Aug (PKl), Sweetwater 27 Sep (ph. G. Graves), San Bernardino NWR 29 Sep (RWe), Sweetwater 11 Oct (ACo), Peña Blanca L. 27 Oct+ (CCa), and at Santa Gertrudis Lane 6 Nov+ (MLe, CMc).

The slow but steady re-expansion of the range of Rufous-winged Sparrow continued. Reports from Cochise Co. came from Saint David continuing through 7 Aug (RB), one at the Madison St. drip in Benson through 18 Sep (JSab), and up to four at San Bernardino NWR 2 Sep-15 Oct (RWe). This species should be sought (and reported when found) in appropriate habitat throughout Cochise Co. During the Atlas surveys, Botteri’s Sparrows were found no farther north than the foothills of Mt. Fagan s. of Vail, so up to three singing in appropriate habitat during the third week of Aug sw. of Oracle (B. Bristow, B. Taubert) and again 18 Sep (ph. DJ) were remarkable. Whether this was a temporary result of enhanced habitat following good winter rains or an actual range expansion remains to be seen. Keep an ear out for their song. Clay-colored Sparrow is a rare fall transient in the area, becoming less uncommon the farther south and east one goes in the region. This season there were reports of 12 found during the period 21 Aug-28 Oct. A slate-colored Fox Sparrow was reported at Peña Blanca L. 28 Nov (JM). The other forms of Fox Sparrow are “review species” in Arizona and require documentation for inclusion in AZFO seasonal reports. Swamp Sparrow is a rare transient and winter resident in the region. This season 11 were reported 27 Oct-28 Nov with a few remaining after initial discovery. Seven White-throated Sparrows were reported 8-30 Nov. A Dark-eyed Junco of the “dorsalis” form was reported in upper Madera Canyon 29 Oct (LHal), a typical time for this rare visitor to the region.

Tanagers of multiple species were seen on dates considered late. Hepatic Tanager is rated “rare” after the third week of October; eight were reported in that time frame. Summer Tanager becomes “casual” after mid-October; one to two shuttled between Roger Road STP and Sweetwater 5 Oct+ (DSt, JBoc), one was at Proctor Rd. 30 Oct (LHal), and one was near Tubac 26 Nov (MPo, MSt). Western Tanager is rated “casual” after the third week of October; eight were reported in that date range this season, with the latest found on 6 Nov. Rose-breasted Grosbeak reports were many fewer than in recent years, with only two reported. A Black-headed Grosbeak heard near Santa Gertrudis Lane 7-8 Nov (WR) was late/”casual”. The same status applies to single Blue Grosbeaks at Tubac 6 Nov (MLe, CMc) and Whitewater 17 Nov (SW). Up to four Varied Buntings lingered in the region to casual dates, with the latest at San Bernardino NWR 24 Oct (RWe). Painted Bunting is a “molt migrant” to se. Arizona, expected each fall; an above average 24 were reported this season from 3 Aug-17 Aug. Good numbers of Dickcissels were reported this season, with 16 reported 21 Aug-16 Oct. Most remarkable was a group of four in Johnson grass in the Santa Cruz R. bed adjacent to Sweetwater.

Orchard Oriole is a casual transient in the region. Singles were reported at San Bernardino NWR 21 Aug (RWe) and San Simon Cienega 8 Sep (RWe). Hooded Oriole is considered “casual” after the third week of October, so reports of singles lingering at Saddlebrooke through 15 Nov (B. & P. Bowers) and in nw. Tucson in late Oct (LN) were of note. Single late Bullock’s Orioles were along the Santa Cruz R. s. of Carmen 12 Oct (JY et al.) and near Santa Gertrudis Lane 31 Oct (MBr et al.). Late Scott’s Orioles were at Peña Blanca L. 29 Oct (CCa) and below Carr Canyon 2 Nov (HBr). Lawrence’s Goldfinch is an irruptive species, which is absent many winters and abundant in others. This fall there was but a single report of two at San Bernardino NWR 7 Oct (RWe). Reports of Evening Grosbeak have diminished greatly in the past decade or more in the region. Of note was one visiting a feeder in Willow Canyon, Santa Catalina Mtns. 23 Oct (BBi).
