About the Common Potoo

The common potoo (Nyctibius griseus), also known as the kakuy or urutaú, 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.

The common potoo was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the nightjar-like species in the genus Caprimulgus and coined the binomial name Caprimulgus griseus. Gmelin based his description on "L'engoulevent gris" from Cayenne that had been described from a preserved specimen in 1779 by the French polymath Georges-Louis Leclerc, Comte de Buffon. The common potoo is now one of the seven potoos placed in the genus Nyctibius that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. The genus name is from the Ancient Greek nuktibios meaning "night-feeding", from nux night and bios "life". The specific epithet griseus is Medieval Latin meaning "grey".
