Size: 7-8" (18-20cm). A large, stocky, short-tailed flycatcher. Adults a drab olive-brown on the back and flanks. Olive of flanks almost meets on its white chest, giving it the appearance of wearing a vest. Head large with a thick bill. Immatures are similar to adults, but are often darker above and below.
Similar Species- Western Wood-Pewee is smaller, paler and longer tailed. Also lacks the vested look.
The song of the Olive-sided Flycatcher is a very distinct, three-parted whistle with the second note higher than the first and descending to the third. Some say it sounds like: Quick-Three-Beers! Call is a repetitious pip-pip-pip.
Breeds from portions of Alaska and Canada, south (west of Rockies) to northern Baja California, Arizona, New Mexico, and western Texas, and (east of Rockies) through portions of Midwest, Northeast, and middle Atlantic states. Winters in mountains of South America, and in small numbers in Central America and southern Mexico.
Found in forests and woodlands (especially in burned-over areas with standing dead trees) such as taiga, subalpine coniferous forests, mixed forests, boreal bogs, muskeg, and borders of lakes and streams. Idaho study found species responded psitively in numbers to single-tree logging.
Hunts from perch. Builds cup-shaped nest in coniferous or deciduous tree. Usually territorial in non-breeding areas.
