Black Skimmer – Wikipedia, the free encyclopedia
The Black Skimmer, Rynchops niger, is a tern-like seabird, one of three very similar birds species in the skimmer family. It breeds in North and South America. Northern populations winter in the warmer waters of the Caribbean and the tropical and subtropical Pacific coasts, but the South American races make only shorter movements in response to annual floods which extend their feeding areas in the river shallows.
