Endemic to Australia. They are common across the southern half of Australia but absent from the more arid country of the north.



There are two subspecies[1]:


Deep, still lakes and wetlands with areas of both open water and reed beds.


Rarely seen in flight or on dry land. They sleep on the water at night, with the head tucked into the body or under a wing.

Shy birds, if they feel under threat, will dive only to resurface some distance away


Water beetles, yabbies, water snails, freshwater shellfish, a variety of aquatic plants and fish.


During courtship the Musk Duck blows its neck and cheeks out and expands the bladder to a diameter of 100-150mm.
The female builds a platform nest with a shallow cup, of plant material. It is usually lined with fine plant matter in tall reeds, in areas of deep water for protection. The clutch consists of 3-4 eggs.
