Neotropic Cormorant
Phalacrocorax brasilianus (Gmelin, 1789)
Also calledBiguascharbe (deu) · Cormoran olivâtre, Cormoran vigua (fra) · Cormoran vigua (fra) · Cormorán Neotropical (Pato Cuervo) (spa) · Cormorán oliváceo (spa) · cormorán (spa) · pato balsero, cormorán (spa) · flodskarv (nob) · Olivenscharbe (deu) · bigua aalscholver (nld)
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 United States south through Mexico and Central America to southern South America, where it is called by the indigenous name of biguá. It also breeds in the Bahamas, Cuba, and Trinidad. It can be found both on coasts (including some mangrove areas) and in inland waters. There are at least two subspecies: N. b. mexicanum from Nicaragua northwards and N. b. brasilianum further south. In Peru, the neotropic cormorant is used by the Uru people for fishing.

Description
This bird is 64 cm (25 in) long with a 100 cm (39 in) wingspan. Adult males weigh from 1.1 to 1.5 kg (2.4 to 3.3 lb), adult females 50 to 100 g (1.8 to 3.5 oz) 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 grayer than the rest of the body. Juveniles are brownish in color.
What it does
Its diet consists mainly of small fish, but will also eat tadpoles, frogs, aquatic insects (such as dragonfly nymphs), and shrimp. Information about its prey is sparse, but inland birds seem to feed on small, abundant fish in ponds and sheltered inlets, less than 10 cm (3.9 in) in length, with an individual weight of a gram or two, such as Poecilia species especially the sailfin molly Poecilia latipinna. This cormorant forages for food by diving underwater, propelling itself by its feet. Its dives are brief, between 5 and 15 seconds. It is also known to forage in groups, with several birds beating the water with their wings to drive fish forward into shallows.
