Known to the Noongar people as ‘Karrak’, the Red-tailed Black Cockatoo numbers have dramatically declined over the years due to the development of forests and woodlands, competition for nest hollows with native and exotic species and the impact of fire.

Adult males have a characteristic pair of bright red panels on the tail that gives the species its name. They are seed eaters and cavity nesters and are usually found in eucalyptus woodlands, or along water courses and they depend on trees with fairly large diameters.

There are three subspecies of Red-tailed Black Cockatoo in Western Australia. Only the south-western population referred to as naso (due to its large bill) is listed as Vulnerable.
