About the Acadian Flycatcher

The Acadian flycatcher (Empidonax virescens) is a small insect-eating bird of the tyrant flycatcher family. Adults have olive upperparts, darker on the wings and tail, with whitish underparts; they have a white eye ring, white wing bars and a wide bill. The breast is washed with olive.
