Eastern Wood Pewee
Contopus virens
The eastern wood pewee is 13.5–15 cm (5.3–5.9 in) in length and weighs around 14 g (0.49 oz). Wingspan ranges 9.1–10.2 in (23–26 cm). The sexes are alike. The adult is gray-olive on the upperparts with light underparts, washed with olive on the breast. Each wing has two pale 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 "pe-wee" with a rising note at the end.

Adults of the nominate subspecies have a dark blackish gray crown with a slight crest, white to grayish white lores, and a thin white eye-ring on an otherwise grayish olive face. Their back is sooty olive-gray and their rump and uppertail coverts brownish olive with a hidden white feather tuft on either side of the rump. Their wings are mostly dusky. Voice: The southern tropical pewee's song is a "clear emphatic whistled pee-heeuw!, repeated at intervals". Its call is a "very short note typically repeated several times...pip..pip..pip..pip..pip....". The song and call have also been written as a "descending tjeuuw" and a "very high, staccato wic wic-" respectively. The species sings and calls at any time of day though more in the morning.
