Waterfowl Commonly Seen in Practice

Black swan

Black Swan

Native to the wetlands of southern Australia and Tasmania, black swans (Cygnus atratus) have been introduced to New Zealand, Europe, and North America. Black swans live in lakes, rivers and swampland in fresh, salt or brackish water.

As the name implies, this species is mostly black with a long, arched neck and raised eyebrows. Some of the wing feathers are white. They also have red or pink irises and red bills with a white line. Cygnets are grey-brown with light tipped feathers and a lighter bill. The cob (male) is slightly larger than the female or “pen”.

Black swans eat aquatic vegetation and other plants. They also occasionally eat insects.
