Yungas Pewee approximately 16–18 cm in length, with a slender and relatively elongated appearance. It has an upright posture and usually perches on exposed branches, especially dead ones, that protrude above the canopy. The head is large and shows a conspicuous, triangular, erectile crest. The plumage is predominantly lead-gray, with a slight olive tinge on the back and rump. The throat is somewhat lighter than the rest of the underparts, while the belly is light gray and becomes whitish or slightly yellowish toward the undertail coverts. The wings show two thin whitish wing bars and narrow pale edges on the flight feathers. The iris is dark brown, it has a thin whitish eye-ring, black legs, and the bill has a black upper mandible and a yellowish or yellow-orange lower mandible. Both sexes are similar, while juveniles are browner and have ochre tones on the wing bars and underparts.
It differs from the very similar Fuscous Flycatcher (Contopus cinereus), with which it may coexist in the Yungas, by its larger size, more elongated appearance, generally more horizontal posture, relatively shorter tail, more developed crest, and different vocalization.
Geographic distribution: It is a widely distributed species throughout the Andes and other mountainous regions of South America, from Venezuela and Colombia to northwestern Argentina, with six recognized subspecies. Throughout its range, it occupies environments between approximately 500 and 3,000 m a.s.l., depending on the region. In Argentina, it is represented by the subspecies Contopus fumigatus brachyrhynchus, whose distribution extends from eastern Bolivia to northwestern Argentina, in the provinces of Jujuy, Salta, Tucumán, and Catamarca. It is considered a resident species, although local altitudinal movements may occur.
Habitat: It inhabits humid mountain forests, forest edges, clearings, and other open woodland environments, generally in mountainous regions. In Argentina, it occurs in the Yungas, from the piedmont rainforest to montane forest, usually reaching 1,800 m a.s.l., although it may occasionally be recorded at higher elevations, in ecotones and ravines above the upper limit of the Yungas, with records near 2,700 m a.s.l. It mainly frequents the middle and upper vegetation strata, using exposed perches from which it captures insects.
Diet: It feeds mainly on flying insects and other small arthropods. It usually captures its prey through long, elastic flights from an exposed perch, frequently returning to the same perch after each sortie.
Behavior: It is generally observed alone or in pairs. It remains conspicuously perched on dead or exposed branches protruding above the canopy, from where it actively watches its surroundings. After each hunting flight, it usually returns to the same perch, making characteristic vibrating movements of the tail when landing again. Its most frequent vocalization consists of a series of clear and loud notes generally transcribed as "kuíp... kuíp... kuíp", as well as melancholy, prolonged whistles emitted mainly during the breeding season.
Nesting: It builds a cup-shaped nest made of mosses, lichens, and plant fibers, firmly attached to horizontal branches in trees. The clutch generally consists of two whitish eggs with sparse brown and lavender spotting. Both members of the pair participate in feeding the nestlings.
Conservation status: Considered Least Concern (LC) at the international level. In Argentina, it has no national threat category. It is a relatively common species within suitable habitats and tolerates a certain degree of disturbance, occurring in numerous protected areas throughout its range.
