Eastern Wood Peewee


Order: Passeriformes
Family: Tyrannidae
Genus: Contopus
Species: C. virens

Identifying Characteristics:

-Medium-sized flycatcher

-Adults are grey-olive on the upperparts with light underparts, washed with olive on the breast. They have two wing bars, and the primary remiges are long, giving the wingtip a slim and very pointed appearance. The upper part of the bill is dark, the lower part is yellowish

-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 at the end

- Juvenile similar to adult, but wingbars buffier

Special Adaptations:

-Eastern Wood-Pewee: Breeds from eastern Great Plains to the Atlantic Ocean, ranging from southern Canada (Saskatchewan to the Maritime Provinces) to northern Florida, the Gulf coast and central Texas. Spends winters in the tropics.

-Preferred habitats include northern hardwood, pine-oak, oak-hickory, bottomland hardwood, southern pine savannah, and midwestern forests; also found in orchards, parks, roadsides, and suburban areas.

-One potential cause of their decline is the overpopulation of white-tailed deer in the Eastern forests. In areas with high deer density, the intermediate canopy is disturbed by browsing, affecting the foraging space of the flycatcher
