|Colin says: Black Swan - Cygnus atratus. |
Black Swans typically have a body length of up to 142 cm, with the females being smaller than the males. In adults, the body is mostly black, with the exception of broad white wing tips, which are visible in flight. The bill is a deep orange-red, paler at the tip, with a distinct narrow white band towards the end. Younger birds are much greyer in colour, and have black wing tips. It is the only entirely black-coloured swan in the world.
