General Description

Body dark grey-brown and mottled with fine white patches. Bill scooped dark grey, or with an orange base (if breeding). Front of wings white underneath. Body up to 60 cm long.

Biology

These ducks often rest on fallen logs and sand areas during the day. Breeding occurs from September to December, or after significant rains. The species is nomadic and often rare, but can have irruptive population booms when large numbers of birds form migratory groups, probably due to changes in their food supply.

Distribution

South-western and south-eastern mainland Australia and Tasmania.

Habitat

Inland wetlands, lignum swamps, occasionally coastal wetlands.
