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.

A unique two-note song described as "ka-zeep" helps to identify this species.

Measurements: Length: 5.5–5.9 inches (14–15 cm) Weight: 0.4–0.5 ounces (11–14 g) Wingspan: 8.7–9.1 inches (22–23 cm) Originally described in 1810 by ornithologist Alexander Wilson, its first scientific name was Muscicapa querula.
