The dark pewee (Contopus lugubris) is a small passerine bird in the tyrant flycatcher family. It is endemic to the highlands 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.
