Not an official British Bird, it is a native Australian bird. but there are many escapees from collections, that are living in the wild. 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.
The Black Swan can sometimes have a same-sex lifestyle, which can be advantageous in some situations, but not in others. However, having a partner is a requisite for building a nest and keeping a territory, and an opposite-sex partner may not always be available when forming pairs. Thus, the ability to form a male pair is a normal part of the black swan’s social behaviour and an example of a flexible life strategy in the species.
