BIRDWATCH
Call of The Wild
The summer sound of the Eastern forests
By Susan Campbell
It is the sound of summer: You may not be paying attention, but it’s there. The slurring “pee-a-wee” of the eastern wood-pewee is echoing all over central North Carolina at this time of year. On the hottest of afternoons this bird continues to call even though its brethren are now quiet. The spring cacophony of breeding birds may have been replaced by the buzzing of cicadas and chirping crickets, but the pewee continues making his trademark vocalization. The species has long been considered a hallmark of Eastern forests. Although not as plentiful as it was before humans began altering the landscape, it can still be found widely throughout the region.
Eastern wood-pewees are flycatchers: carnivorous birds that have the talent for snapping insects out of midair. They are acrobatic fliers that use a perch to scan for large, winged insect prey such as dragonflies, butterflies, moths and beetles. As a result of this foraging strategy, pewees spend much of their time in the open during the warmer months. However, if it were not for their loud calls, these little birds would be easily overlooked. Both males and females are a drab gray-brown above, dusky below, and have buff barring on their wings.
Flycatchers found in the Eastern United States are, as a whole, not a colorful bunch. They tend to be brownish with subtle differences in bill shape, tail length or the color of the small feathers on the wing or around the eye. Habitat may lend a clue, since they have preferences for different types of vegetation. When they vocalize, however, it is a different story. In fact, the eastern wood-pewee has virtually indistinguishable plumage from the western wood-pewee, which is found closer to the West Coast. The western wood-pewee makes a nasal “bree-urr” call that has a much rougher quality in tone. These birds may give a thin, whistled “peeaa” as well. Generally, the quality of the vocalizations is very different from that of our Eastern birds.
Given their diet, the eastern wood-pewee is not likely to appear at a feeder. However, this species may frequent birdbaths or water features within their territory. Also, individuals tend to use the same perches for foraging and can be found predictably in an area. They prefer forest edges so they’re easier to spot than their forest-dwelling cousins, such as the Acadian or willow flycatcher. Pewees also hover for very short periods to catch prey, and will actively move through the vegetation in search of caterpillars and slower moving insects in the canopy. They tend to utilize the midstory in locations where there are deciduous trees. As a result, it is believed that their occurrence in some areas of the Northeast has been affected by the over-grazing of white-tailed deer. The loss of smaller trees and shrubs has eliminated not only pewee perches but the necessary vegetation for their prey species.
Female eastern wood-pewees build a shallow cup nest of woven grasses lined with plant fibers, animal fur and/or moss. It’s well camouflaged on the outside with lichens and blends in with the horizontal limb that it is built on. Pewees have a limited ability to defend their eggs and young, so invisibility is the name of the game.
These little birds are migratory, spending the winter months in South America, where prey is abundant. Eastern wood-pewees can be found through Peru down into Brazil during the non-breeding season. They become active, solitary hunters that pursue prey in a variety of habitats that time of the year.
Before they begin to head south in August, see if you can spot one of these vocal, talented fliers. You may have to look closely to find this familiar summer friend motionless on a favorite perch.
