About the black-necked swan
The black-necked swan is a South American waterfowl found in Argentina, Brazil, Chile, Uruguay and the Falkland Islands. It is the largest waterfowl native to South America, though the lightest true swan on average, with adults 102 to 126 cm (40 to 50 in) long. The body is white, the head and neck black, with a white stripe behind the eye and a prominent red knob at the base of the bill. It lives in freshwater marshes, shallow lakes, brackish lagoons and sheltered coasts, feeding almost entirely on aquatic plants. Pairs are believed to bond long term and build a mound nest of vegetation, laying four to eight eggs.

AZAThe Association of Zoos and Aquariums. Accredited members have passed an independent inspection of animal care and welfare, safety, conservation and education, repeated every five years. Many smaller facilities never apply, so “not accredited” isn't a verdict on its own. What accreditation means · How we check this
