The black swan is a large waterbird, a species of swan which breeds mainly in the southeast and southwest regions of Australia. Within Australia, the black swan is nomadic, with erratic migration patterns dependent on climatic conditions. It is a large bird with black plumage and a red bill. It is a monogamous breeder, with both partners sharing incubation and cygnet-rearing duties.

How To Identify

They are large, imposing swans covered in glossy slate-black feathers. A defining feature is the stark contrast provided by their distinctive bright white bill.

Habitat

Black swans typically inhabit coastal and inland waterways including lakes, swamps, estuaries, and river systems across southern and eastern Australia, with introduced populations now found on other continents.

Behaviour

They are highly vocal birds that communicate through loud honking calls and elaborate synchronized swimming displays, and they often feed while swimming by dabbling or up-ending in shallow water.

Native Range

The black swan is native to Australia and Australasia.

Did You Know?

Black swans were unknown to Europeans until Dutch explorers reached Australia in the 1600s, making their discovery one of the most surprising animal revelations of the Age of Exploration. They can live over 40 years in the wild and form lifelong pair bonds.
