| Contopus cooperi (Swainson, 1832) |
The Olive-sided Flycatcher, Contopus cooperi, is a passerine bird. It is a medium-sized tyrant flycatcher.
Adults are dark olive on the face, upperparts and flanks. They have light underparts, a large dark bill and a short tail.
Their breeding habitat is coniferous woods across Canada, Alaska and the northeastern and western United States, and other types of wooded area in California. The female usually lays 3 eggs in an shallow open cup nest on a horizontal tree branch. The male defends a large area around the nesting territory. Both parents feed the young birds.
These birds migrate to Central America and the Andes region of South America.
They wait on a perch at the top of a tree and fly out to catch insects in flight.
The song is a whistled quick-three beers. The call is a rapid pip pip pip.
The numbers of this bird are declining, probably due to loss of habitat in its winter range.
