Southern Tropical Pewee

The southern tropical pewee is 13.5 to 14.5 cm (5.3 to 5.7 in) long and weighs about 10 to 15 g (0.35 to 0.53 oz). The sexes have the same plumage. 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.
