The common potoo, or kakuy, or urutau is one of seven species of birds within the genus Nyctibius. It is notable for its large, yellow eyes and a wide mouth. Potoos are nocturnal and are related to nightjars and frogmouths. They lack the characteristic bristles around the mouths of true nightjars.
Region
Neotropics
Typical Environment
Occurs from southern Central America through much of northern and central South America, including Trinidad. It favors forest edges, clearings, gallery forests, secondary growth, and savannas with scattered trees. Often found along rivers, in plantations, and near lights that attract insects. By day it roosts motionless on stumps or exposed branches, relying on cryptic plumage. It avoids the densest interior of tall rainforest but uses gaps and edges extensively.

This nocturnal bird relies on extraordinary camouflage, perching upright by day and resembling a broken branch. It has eyelid slits that let it watch for danger while appearing to have its eyes closed. It lays a single egg directly on a shallow depression of a branch or stump with no built nest. Its wide, gaping mouth helps it snatch flying insects on nocturnal sallies.
