The coscoroba swan is a species of waterfowl which originates from South America. Both males and females have white feathers and a coral-coloured beak. Coscoroba swans are often mistaken for white geese because of their short necks and the lack of black pigment around their eyes.
This swan can measure up to 115 centimetres and weigh between 3.8 and 4.6 kilograms.
Experts believe they are related to whistling ducks, but they are classified as part of the swan family.
Coscoroba swans are not likely to be threatened by extinction in the near future.
Experts state that there could be as many as 25,000 swans left in the wild. In areas such as Chile there has been a rapid decline due to the loss of habitat.
Coscoroba swans eat grasses, small water plants, mussels and fish.
