Description

The Yellow-tailed Black Cockatoo is a large, majestic parrot easily recognized by its brownish-black plumage, yellow cheek patches, and the bright yellow panels on its tail. Known for their loud, wailing calls and powerful bills used for tearing into wood in search of beetle larvae, these birds are iconic symbols of Australian eucalyptus forests.

Colour & Pattern

Striking coloration featuring a black or dark brownish-black tip and upper vane, transitioning into a vibrant yellow or orange-yellow band towards the base, with a prominent bright yellow-orange central rachis.

Barb Structure

Tightly interlocked pennaceous structure along the vane with strong hooklets, clean and intact barbs with no afterfeather.

Texture & Surface

Stiff, smooth, and slightly glossy texture with rigid vanes designed to withstand aerodynamic stress during flight.

Key Features

Vivid yellow-orange central rachis contrasting sharply with dark blackish vanes and a bright yellow-orange subterminal or basal band.

Habitat

Eucalypt forests, wooded areas, timbered farmlands, and pine plantations across southeastern Australia.

Geographic Range

Endemic to southeastern Australia, including New South Wales, Victoria, South Australia, and Tasmania.

Ecological Role

Acts as an important seed predator and forest health indicator by controlling wood-boring insect populations and aiding in forest regeneration.

Similar Species

Glossy Black Cockatoo (Calyptorhynchus lathami) and Red-tailed Black Cockatoo (Calyptorhynchus banksii), distinguished by different tail panel coloration and smaller overall body size.

Interesting Facts

These cockatoos have a specialized bill capable of stripping bark and chewing deep into dead wood to extract heavy-bodied wood-boring beetle larvae, a primary food source.

Condition Notes

Good condition with intact barbs, clean edges, and minimal signs of wear or fading.
