The Anhinga is the only darter in the New World. Superficially cormorant-like, it is easily distinguished by its long, serpentine neck, dagger-like bill, and long, square-tipped tail. The Anhinga is widespread in Neotropical freshwater wetlands from Mexico and Central America south to Ecuador and east of the Andes south to northern Argentina. It is also present on Cuba and Trinidad and Tobago. It feeds largely on fish, using its long bill to spear prey on underwater dives. It places its nest of sticks and leaves in vegetation above water, often in colonies with cormorants (Phalacrocoracidae) or Ciconiiformes. While this species is mostly sedentary, northern populations migrate south to winter along the Gulf Coast and in Mexico. Males are largely black in plumage, with white markings on the scapulars and wing coverts. Females are similar, but are buffy on their throats, necks, and upper breasts.
