Nannopterum brasilianum

The Neotropic Cormorant or Olivaceous Cormorant (Nannopterum brasilianum) is a medium-sized cormorant found throughout the American tropics and subtropics, from the middle Rio Grande and the Gulf and Californian coasts of the USA south through Mexico and Central America to southern South America. It also breeds on the Bahamas, Cuba and Trinidad. It can be found both at coasts (including some mangrove areas) and on inland waters. There are at least two subspecies: P. b. mexicanus from Nicaragua northwards and P. b. brasilianus further south.
