Location: National Elk Refuge, Jackson, Wyoming

There are two subspecies (Audubon’s and Myrtle) of Yellow-rumped Warbler. Both subspecies have a yellow rump patch, which may be obscured by the wings except when in flight. Males of both species also have a yellow spot on the crown of their heads and on the sides of their breasts (which may be partially concealed by their wings). As shown in this image, males of the Audubon’s subspecies have a yellow throat and an incomplete white eye ring, while males of the Myrtle subspecies have a white throat and a black mask.
