grace's warbler Setophaga graciae

A small gray warbler with a bright yellow throat and eyebrow. All plumages are very similar; immatures are slightly duller and browner. Occurs in pine forests from the southwest U.S. to Nicaragua. Usually stays high in the canopy. Listen for a choppy musical trill, often broken into two parts. Compare with “Audubon’s” Yellow-rumped Warbler, which has yellow on the sides and rump no yellow eyebrow, and yellow restricted to the throat (not breast).
