Empidonax difficilis

The Western Flycatcher is a small olive bird with a broad pale eye-ring, two wing bars and a flat-headed appearance. It lives in shaded conifer and mixed forests of western North America. The bird catches insects in short flights from a perch and often returns to the same branch. Voice is usually more useful than plumage for separating it from similar Empidonax flycatchers. Pacific-slope and Cordilleran Flycatchers were combined again as this species in 2023.
