Coscoroba Swan (Coscoroba coscoroba)
Although it is known as a “swan” the Coscoroba swan is not a member of the genus Cygnus (True Swans) and instead belong to the monotypic genus Coscoroba. Coscoroba swans breed in southern South America, ranging from southern Chile and central Argentina south to the Tierra del Fuego and the Falkland Islands. In winter Coscoroba swans will fly north to central Chile, northern Argentina, Uruguay and the southeastern tip of Brazil. They typically inhabit well-vegetated swamps and lagoons and other wet areas. Like true swans and other waterfowl Coscoroba swans feed mainly on grasses and other small water plants, however they will feed on small invertebrates and fish as well.
