Black-throated Green Warbler (Setophaga virens), Sasco Road at Santa Cruz River, Pinal County
This Black-throated Green Warbler was found by
Brian Walsh on 16 January 2017 and photographed by Laurens Halsey on 17 January 2017
Prior to 1990 there were about 30 records for
Arizona, but it has been much scarcer since with only
about a half dozen records. This pattern of decreased
occurrence since 1990 is similar to that of several
other northerly breeding eastern warblers that are much
less common as vagrants to the state than previously.
However, in the past few years several Black-throated
Green Warblers have been documented, and the frequency
of records of this species may be increasing.
Distinguished from Townsend's Warbler and other
species by yellow around the vent; broad black streaks
on the upper chest, side, and flanks; and two-toned
face, yellow with mustard cheeks.
