The olive-sided flycatcher (Contopus cooperi) is a passerine bird. It is a medium-sized tyrant flycatcher.
Description
The olive-sided flycatcher is a stocky bird with long wings. The bird has gray brown top feathers, dark gray sides, and a white chest. Olive tones may be visible in optimal lighting and fresh plumage.
Measurements:[2]
- Length: 7.1-7.9 in (18-20 cm)
- Weight: 1.0-1.4 oz (28-40.4 g)
- Wingspan: 12.4-13.6 in (31.5-34.5 cm)
Behavior
Feeding
They wait on a perch at the top of a tree and fly out to catch insects in flight.
Breeding
The female usually lays three eggs in a 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.
Migration
Of all the flycatcher species that breed in the United States, the olive-sided flycatcher has the longest migration. Some olive-sided flycatchers migrate up to 7,000 miles traveling between central Alaska and Bolivia.[2]
Flight peculiarities
The flight of this bird is peculiar. It makes a kind of vertical free fall after climbing into the air ending in singing with the head lifted up (see impression on pictures)
Status and conservation
The numbers of this bird are declining, probably due to loss of habitat in its winter range.
