Nycticorax is a genus of night herons. The name Nycticorax derives from the Greek for “night raven” and refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the Black-crowned Night Heron.
Adults are short-necked and stout herons; they typically have a dark crown and back with the remainder of the body white or grey, and short legs. Young birds are brown, flecked with white and grey.
They stand at the water's edge, and wait to ambush prey, mainly at night. They primarily eat small fish, crustaceans, frogs, aquatic insects, and small mammals. During the day they rest in trees or bushes.
