Yellow-rumped Warbler (Audubon's) seen on a cold and grey spring day.
The Yellow-rumped Warbler has two distinct subspecies that used to be considered separate species: the "Myrtle" Warbler of the eastern U.S. and Canada's boreal forest, and "Audubon’s" Warbler of the mountainous West. The breeding "Audubon's" male has a yellow throat and the breeding ''Myrtle'' male has a black mask and a white throat among other differences. Intergrades show intermediate traits.
