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.

Western Wood Pewee
Contopus sordidulus
Adults are gray-olive on the upperparts with light underparts, washed with olive on the breast. They have two wing bars and a dark bill with yellow at the base of the lower mandible. This bird is very similar in appearance to the eastern wood pewee; the two birds were formerly considered to be one species. The call of C. sordidulus is a loud buzzy peeer; the song consists of three rapid descending tsees ending with a descending peeer. The bird is about 5.5–6.3 in (14–16 cm) in length, 0.4–0.5 oz (11–14 g) in weight, and has a wingspan of 10.2 in (26 cm).
