Anna's x Broad-billed Hummingbird (Calypte anna x Cynanthus latirostris), McDowell Mtn. Ranch, Maricopa County

This probable Anna's x Broad-billed Hummingbird hybrid was found by Brian Ison on 15 July 2017 and photographed by him on multiple dates into late August.

Hummingbird hybrids are regularly documented and both Anna's and Broad-billed have been documented hybridizing with other species. However this is possibly the first documentation of a hybrid between these two species though there has been a least one possible Costa's (C. costae) x Broad-billed. Broad-billed Hummingbird has been expanding north in Arizona and has recently become regular locally in the Phoenix area, while Anna's has been a common breeder in the Phoenix since the 1970's after expanding east.

Molting male most similar to a Broad-billed Hummingbird with long, dark notched tail, some red to the base of the bill (difficult to see in the field), dark gorget. Features of Anna's include the slightly flared gorget, more mottled underparts, and spotted undertail coverts. Sound recordings can be found here.
