Olive-sided Flycatcher
Contopus cooperi
The adult Olive-sided Flycatcher is a large, dark-sided tyrant flycatcher of boreal forest openings, burns, bogs, and woodland edges with tall exposed perches. It hunts by sitting upright on a snag, launching after bees, wasps, flies, moths, and other flying insects, then often returning to the same perch. Males are known for a loud, whistled song often rendered as “quick, three beers,” used to advertise territory. This species is a long-distance migrant and has declined in many areas as breeding and wintering habitats have changed.
