Gray Flycatcher- More gray overall rather than olive. Gray moves the tail
downward rather than upward. Also has an inconspicuous eye ring rather than
Dusky Flycatcher- Has a bicolored bill, narrow white eye-ring, thinner bill; winter bird shows much more yellow than the one we were watching.
Hammonds Flycatcher: has a slight, tear-drop shaped eye-ring like the one we were observing, but has a differently shaped head, shorter tail and smaller bill. Bill is also darker in Hammond's than on the one we were observing.
