Genus Calyptorhynchus
Red-tailed Black-Cockatoo - Adult Red-tailed Black Cockatoos are around 60 centimetres in length and sexually dimorphic. Males are completely black in colour, excepting their prominent red tail bands; the slightly smaller females are brownish-black with yellow barring and spotting and have yellow-orange tail stripes. The species is usually found in eucalyptus woodlands, or along water courses. In the more northerly parts of the country, these cockatoos are commonly seen in large flocks. They are seed eaters and cavity nesters. As such, they depend on trees with fairly large diameters, generally Eucalyptus. Populations in southeastern Australia are threatened by the reduction in forest cover and by other habitat alterations. Of the black cockatoos, the red-tailed black is the most adaptable to aviculture,

Yellow-tailed Black-Cockatoo - The Yellow-tailed Black Cockatoo is a large cockatoo native to the south-east of Australia measuring 55–65 cm in length. It has a short crest on the top of its head. Its plumage is mostly brownish black and it has prominent yellow cheek patches and a yellow tail band. The body feathers are edged with yellow giving a scalloped appearance. The adult male has a black beak and pinkish-red eye-rings, and the female has a bone-coloured beak and grey eye-rings. In flight, Yellow-tailed Black Cockatoos flap deeply and slowly, and with a peculiar heavy fluid motion. Their loud eerie wailing calls carry for long distances.

Adult Glossy Black-Cockatoos may reach 50 cm in length and sexually dimorphic.
