The Nankeen Night Heron - Nycticorax caledonicus - is coloured cinnamon-rufous on the back and sides merging into tints of cinnamon at the sides and blending into a white breast and underparts. Crown and bill are black; pale green skin between eye and beak. Legs are thick and pale green; tail is short. Breeding adults have long white plumes from the back of the neck. Males and females are coloured the same; males are slightly larger (55 to 65 centimetres).

Juveniles are streaked white and pale brown to give a mottled appearance. The head is streaked on juvenile birds turning black on immature ones.
Flies with neck folded back; translucent flight feathers become bright rufous in sunlight.
The Night Heron feeds at night; roosts by day in trees close to water also under jetties and wharves. While roosting the head is hunched down onto the shoulders but is extended when hunting. Found solitary or in groups; often large numbers roost together.
Lives in wetlands, billabongs, flooded grasslands as well as in estuarine environments such as mangroves and tidal channels. Prefers sites with tall vegetation for cover and dense trees nearby for roosting.
Common in the south-east and south-west; scarce in the interior.
