Red Warbler (Cardellina rubra), Rose Canyon Campground, Santa Catalina Mts., Pima County
This Red Warbler was
found by Janet Stein and Janet Moore on 09 April 2018
and photographed by Dave Stejskal and Andy Boyce on the same day.
Red Warbler is a Mexican endemic species that occurs
in the mountains of both eastern and western Mexico. The
gray (black) cheeked subspecies occurs north to at least
n.e. Sinaloa and s.w. Chihuahua while the white-cheeked
subspecies group occurs in central and southern Mexico.
If accepted by the ABC, this would constitute the first
record of this species in Arizona and the U.S. The
origin of this individual will be discussed by the ABC
and the ABA.
This beautiful warbler is unmistakable, but it is worth
discussing the two subspecies groups. As the cheek patch
is white to a light gray in the photos it appears to be
of the southern subspecies group. This appears to be
an After Second Year (ASY) bird as Second Year (SY)
birds apparently show a noticeable molt limit in the
greater coverts and lack red edging to the flight
feathers (fide Oscar Johnson).
