Similar species:

The empidonax flycatchers are very difficult to tell apart. The safest
way to differentiate them is by habitat, range, and voice in the breeding
season. Differences in plumage due to molt, wear and age make the
plumage quite variable. The least flycatcher is the smallest empidonax
with a small bill that makes the head look big. Yellow-bellied flycatcher
is similar in size and shape but is greener above and yellower below.
Willow and alder have less obvious eye rings, longer tails and browner
upperparts. Acadian is larger, bigger-billed, greener above, and yellower
below. In the west, Hammond's is typically darker on the breast. Dusky
and gray are larger and Pacific-slope and Cordilleran have oval eye rings,
are larger, and yellower underneath.
