The northern potoo (Nyctibius jamaicensis) is a nocturnal bird belonging to the potoo family, Nyctibiidae. It is found from Mexico south to Costa Rica and on the islands of Jamaica and Hispaniola. It was formerly classified as a subspecies of the common potoo (Nyctibius griseus) but is now usually treated as a separate species based on differences in vocalizations.
It is a fairly large bird with a length of 38-46 centimetres. It has a long tail, long pointed wings, large head, very short legs and a small bill with a large gape. It is most commonly seen perched motionless in an upright position on branches or posts. The plumage is grey-brown with an intricate pattern of black, grey and cream markings. The cheeks are pale with a dark malar stripe below them. The large eye has a yellow iris which can shine red in light at night. The bird's calls are hoarse and guttural.
The common potoo is virtually identical in appearance but has a very different voice consisting of a series of mournful, wailing whistles. The great potoo is larger and paler with no dark malar stripe.
It has five subspecies distributed across Middle America and the West Indies. N. j. jamaicensis is restricted to Jamaica while N. j. abbotti is found on Hispaniola with a single report from Mona Island in Puerto Rico. N. j. lambi is found in western Mexico extending north as far as southern Sinaloa. N. j. mexicanus occurs in southern and eastern Mexico north to southern parts of San Luis Potosí and Tamaulipas as well as in Guatemala, Belize, El Salvador and Honduras. N. j. costaricensis is the most southerly form, occurring in western Nicaragua and north-west Costa Rica.
