The dusky-legged guan is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is found in Uruguay, northeastern Argentina and southernmost areas of Paraguay and Brazil. In early 2021, the former subspecies P. o. bridgesi, found in southwestern Bolivia and northwestern Argentina, was elevated to species rank as Yungas guan.
Region
Southern South America
Typical Environment
Occurs from southern and southeastern Brazil through eastern Paraguay and northeastern Argentina to Uruguay, favoring humid and semideciduous forests. It inhabits Atlantic Forest, Araucaria moist forests, riparian and gallery woodlands, and forest edges. The species readily uses second-growth, plantations, and even large parks where sufficient tree cover and fruiting trees are present. It spends much time in the mid-story and canopy but also descends to the ground to feed on fallen fruits.

A large forest cracid, the dusky-legged guan plays an important role as a seed disperser by swallowing fruits whole and moving seeds across the landscape. It is generally tolerant of disturbed habitats and can occur near human settlements where hunting pressure is low. In 2021, the former subspecies P. o. bridgesi was elevated to species rank as the Yungas guan. Local populations may decline due to hunting and deforestation, but the species remains widespread.
Temperament
wary but adaptable
Flight Pattern
short rapid wingbeats with occasional glides
Social Behavior
Usually seen in pairs or small family groups and may form loose flocks at rich food sources. Roosts communally in tall trees. Nests are platform-like structures of sticks and leaves placed in trees or dense vegetation; clutch size is typically small. Monogamous pairs defend nesting areas but may tolerate neighbors where resources are abundant.
Migratory Pattern
Resident
Song Description
Vocalizations include deep, resonant hoots and clucking notes, often delivered from a concealed perch at dawn and dusk. Display flights are accompanied by loud wing-whirring sounds. Calls carry far through forest, serving to maintain contact within groups.
