The male glossy black cockatoo is predominantly black with a chocolate-brown head and striking caudal red patches.
The female is a duller dark brown, with flecks of yellow in the tail and collar.
The female's tail is barred whereas the male's tail is patched.
An adult will grow to be about 46–50 cm (18–19.5 in) in length.
The birds are found in open forest and woodlands, and usually feed on seeds of the she-oak (Casuarina spp.)
