    Eastern Wood-Pewee Life History

    Habitat

    Habitat ForestsUsually found in clearings and forest edges, Eastern Wood-Pewees breed in nearly any type of wooded habitat in the eastern United States and southeastern Canada—including mature woodlands, urban shade trees, roadsides, woodlots, and orchards. They prefer deciduous forest but also live in open pine woodlands of the south and mixed hardwood-conifer forest of the north. Although they usually avoid streams in eastern forests, they often nest in riverside habitat in the Great Plains. During spring and fall migration, Eastern Wood-Pewees stop in a variety of habitats with trees and shrubs, including edges, clearings, primary forest, and secondary forest. They spend the winter in wooded, partially cleared, and shrubby habitats of northern South America and possibly Central America, usually below 4,300 feet of elevation.Back to top

    Food

    Food InsectsThe Eastern Wood-Pewee captures small flying insects by sallying out from a dead branch partway up in the canopy. According to one study, they make an average of 36 sallies per hour in the nonbreeding season and almost twice as many—68 sallies per hour—when feeding its young. It may also glean insects from foliage or the ground, sometimes taking advantage of locally abundant prey during insect emergences. Its diet includes flies, bugs, butterflies, moths, bees, wasps, beetles, grasshoppers, crickets, stoneflies, and mayflies. The pewee also eats small amounts of vegetable matter, including the berries and seeds of dogwood, blueberry, raspberry, and poison ivy.Back to top

    Nesting

    Nest Placement

    Nest TreeEastern Wood-Pewees nest in trees and saplings such as elms, oaks, maples, birches. The nest is usually 15–70 feet off the ground.

    Nest Description

    The nest is a small cup made of woven grass—or sometimes weeds, wool, bark strips, twigs, roots, mosses, pine needles, or leaves—covered with lichens that provide superb camouflage. It measures 3 inches across and 1-2 inches high. The inner cup, which is lined with hair, grass, moss, lichens, and plant fibers, measures 2 inches across and 0.5–1 inches deep.

    Nestling Period:16-18 days
    Egg Description:White or creamy with a wreath of brown or purple speckles.
    Condition at Hatching:Helpless, with sparse down feathers and closed eyes.

    Behavior

    Behavior FlycatchingEastern Wood-Pewees are territorial during the breeding season, holding territories that range from about 5-20 acres in size. The male changes his singing patterns in response to other males. He also attacks other species that approach while he is singing, although his territory may overlap with those of Great Crested Flycatchers and Least Flycatchers. Pewees appear to be monogamous; the female incubates the brood while the male brings food. They are solitary during migration and on the wintering grounds.Back to top

    Conservation

    Conservation Low ConcernEastern Wood-Pewee is a common bird, but across its range populations declined by about 51% between 1966 and 2015, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 5.5 million, with 94% breeding in the U.S. and 6% in Canada. The species rates a 10 out of 20 on the Continental Concern Score. Eastern Wood-Pewee is not on the 2016 State of North America's Birds' Watch List. One reason for their decrease may be the high northeastern populations of white-tailed deer, whose browsing may cause changes to the intermediate canopy where pewees forage. Pewees are tolerant of forest fragmentation, since they live in both edge habitat and forest interiors.Back to top

    Backyard Tips

    Like other flycatchers, pewees usually don’t come to feeders. They may visit wooded backyards or property adjacent to patches of forests or woodlands.
