COSEWIC assessment and status report on the Olive-sided Flycatcher Contopus cooperi in Canada

The Olive-sided Flycatcher (Contopus cooperi (Swainson), French: Moucherolle à côtés olive) is a medium-sized songbird 18-20 cm in length. Adults are a deep brownish olive-grey above and on the sides and flanks, with white on the throat, centre of breast and belly. The wings are dark with pale, indistinct wing bars, and the bill is stout. The most distinctive features of the Olive-sided Flycatcher are its tendency to conspicuously perch on the top of tall trees or snags while foraging and the song—a loud three-note whistle: Quick, THREE BEERS!.
