The common potoo, or kakuy (Nyctibius griseus), 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.
