Scientific classification

Kingdom:Animalia
Phylum:Chordata
Class:Aves
Order:Passeriformes
Family:Tyrannidae
Genus:Contopus
Species:C. lugubris
The Dark Pewee (Contopus lugubris) is a small passerine bird in the tyrant flycatcher family. It is endemic to the Talamancan montane forests of Costa Rica and western Panama.
This large, Dark Pewee is found between 1250 m and 2150 m altitude in wet mountain forests, especially at the edges and in clearings, and in adjacent semi-open areas with tall trees. 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 the female builds the nest, lays only two eggs and incubates the eggs for 15–16 days before they hatch.
The only all-dark crested flycatcher in range. Entirely sooty-gray, only slightly paler on throat and belly. More obvious crest than other pewees. Sexes alike. Usually seen singly, perched conspicuously at the forest edge or in a clearing. Listen for “pip” call notes.
