Habitat and Distribution
Their breeding habitat is deciduous, mixed woods, or pine plantations in eastern North America. These birds migrate to Central America and in the Andes region of northern South America. Eastern Wood Pewees arrive relatively late on breeding grounds (e.g., 18 May to 5 June in southern Ontario). They migrate south at a more usual time, leaving sometimes in late August but most often in September.
They feed on insects and other arthropods. Wood pewees wait on a perch at a middle height in a tree and fly out to catch prey in flight, sometimes hovering to pick it from vegetation.
They make an open cup nest made of grasses, bark, and lichen, attached to a horizontal tree branch with spider webs. Nest sites range in height from 4,6 to 18 m . Common nest trees used include oaks (Quercus), pines (Pinus), birches (Betula), and maples (Acer). The female lays almost always 3 translucent -white eggs with brown flecking. Males sometimes mate with two females, simultaneously. The eggs hatch in 12 to 14 days.
Calls and Songs
The songs are basically a mournful whistled pee-a'wee given in a series, which gave this bird its name, and a we-aww with a rising note .
