Nycticorax

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. These are medium-sized herons which often are migratory in the colder parts of their ranges.
