  • FAMILY: Tyrannidae

Basic Description

The Olive-sided Flycatcher whistles an instantly recognizable quick, three beers! across its rugged habitat of coniferous mountain forests, bogs, and muskeg. This husky, barrel-chested flycatcher is the largest of the pewees, with heavy grayish markings on the sides as if the bird is wearing a waistcoat. Olive-sided Flycatchers are vigorous defenders of their territory and nest, chasing rivals and predators with the fervor of a kingbird. Look for them singing from open perches in the highest parts of live or dead trees. These birds are also fairly common in recently burned forests.

Find This Bird

Olive-sided Flycatchers are vocal in spring and early summer, so listen for the abrupt quick, three beers! song of the male as well as for quick, distinctive pip-pip-pip call notes. Once you hear one, look high in conifer tops and especially dead trees to find the singer. The bird’s stocky shape, heavy bill, and heavily marked sides help identify this species even at long range. In winter, look for them in mountain forests of Panama and the northern Andes between about 3,300 and 6,600 feet elevation.
