The Dark Pewee (Contopus lugubris,) is a large, dark pewee that is endemic to the highlands of Costa Rica and western Panama where it occurs from 1250 to 2150 m altitude in wet mountain forests, particularly y at the edges and in clearings, and in adjacent semi-open areas with tall trees.
Outside the breeding season, they are usually seen alone. They feed on insects.
Nesting / Breeding:
The nest is a broad, thick-walled saucer of mosses and lichens, lined with plant fibres. It is placed 5-18 m high across a branch. The eggs are undescribed, but in related species the female builds the nest and incubates a typical clutch of two eggs for 15-16 days to hatching.
It will defend the nest aggressively against larger species.
The Dark Pewee measures about 26.5 cm in length and weighs 23 g.
The plumage above is sooty-grey, darkest on the prominently crested crown. The wings and tail are blackish, the wings having grey feather edges and a weak wing bar. The throat is pale grey, with most of the rest of the underparts a paler olive-grey than the back, becoming yellowish on the lower abdomen.
Males and females look alike, but young birds are browner above and have rufous fringes to the wing feathers.
Call / Vocalization:
Its call is described as an incessant loud whip call and its call as a repetitive fred-reek-fear.
