Neotropic Cormorant
Nannopterum brasilianus
The Neotropic Cormorant 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.
This bird is 64 cm long with a 100 cm wingspan. Adults males weigh 2 kg, adult females 100 grams less. Birds of the southern populations tend to be bigger than the more northerly birds. It is small and slender, especially compared to the larger, heavier-looking Double-crested Cormorant. It has a long tail and frequently holds its neck in an S-shape. Adult plumage is mainly black, with a yellow-brown throat patch. During breeding, white tufts appear on the sides of the head, there are scattered white filoplumes on the side of the head and the neck, and the throat patch develops a white edge. The upper wings are somewhat greyer than the rest of the body. Juveniles are brownish in color.
