A swan is a large waterfowl in the family Anatidae, closely related to geese and ducks. Known for its long neck and graceful swimming, it is one of the largest flying birds.
What it is
Swans belong to the genus Cygnus (most species) and the subfamily Anserinae. They are the largest extant members of the waterfowl family, with heavy bodies, webbed feet, and broad bills. Many species are white, but some, like the black swan, have dark plumage.
Where it lives
Swans inhabit lakes, rivers, ponds, marshes, and coastal waters across temperate regions. They are mainly herbivorous, feeding on aquatic plants. In Canada, the tundra swan is a notable species that breeds in the Arctic and migrates through the country.
Key details
There are about six living true swan species, including the mute swan, whooper swan, trumpeter swan, tundra swan, black swan, and black-necked swan. The coscoroba swan is not generally considered a true swan. Swans are known for their slow wingbeats and outstretched necks in flight.
