Non-breeding adults have dark bill tip and duller red parts. Adult plumage is attained after six full or partial moults over three years. Juveniles have dark bill, iris and legs; plumage is pale grey mottled brown and buff especially on the back and wings.

Lives near coastal and inland waters as well as on cultivated farmland, ponds and rubbish dumps. Found all around Australia, extremely widespread; an extremely adaptable bird; abundant in southern Australia, less common in the north and sporadic inland.
