The black skimmer is a tern-like seabird, one of three similar bird species in the skimmer genus Rynchops in the gull family Laridae. It breeds in North and South America. Northern populations winter in the warmer waters of the Caribbean and the tropical and subtropical Pacific and Atlantic coasts, but South American populations make only shorter movements in response to annual floods which extend their feeding areas in the river shallows.

Skimmers have a light graceful flight, with steady beats of their long wings. They usually feed in large flocks, flying low over the water surface with the lower mandible skimming the water for (in order of importance) small fish, insects, crustaceans and molluscs caught by touch by day or especially at night.
