Description
The Yellow-tailed Black Cockatoo is a large, majestic parrot characterized by its brownish-black plumage, distinct yellow cheek patches, and bright yellow panels on the tail and underwings. Known for its mournful, wailing calls and powerful bill used for extracting wood-boring grubs, it is a prominent fixture of Australian eucalyptus forests.
Colour & Pattern
Striking coloration featuring a vibrant canary yellow base across the mid-section, transitioning sharply to a solid, deep black band at the distal tip. The rachis matches the underlying vane color, being yellow through the central portion and turning black at the tip.
Barb Structure
Tightly interlocked pennaceous barbs forming a smooth, firm vane with strong hamuli (barbicels); no afterfeather visible; barbs are intact and well-conditioned.
Texture & Surface
Smooth, firm, and slightly glossy texture with good rigidity across the vane, offering natural water resistance and durability typical of psittacine flight and tail feathers.
Key Features
Vivid canary yellow background color sharply contrasted by a solid jet-black terminal band at the tip, paired with the robust shaft characteristic of large cockatoo tail feathers.
Habitat
Eucalypt woodlands, pine plantations, and temperate forests across southeastern Australia.
Geographic Range
Endemic to southeastern Australia, ranging from southern Queensland through New South Wales and Victoria to Tasmania and South Australia.
Ecological Role
Acts as a primary ecosystem engineer and seed predator, helping control wood-boring insect populations and aiding in forest regeneration through seed dispersal.
Similar Species
Glossy Black-Cockatoo (Calyptorhynchus lathami) and Red-tailed Black-Cockatoo (Calyptorhynchus banksii), which can be distinguished by different tail panel coloration (red or smaller orange-red bars) and smaller overall body sizes.
Interesting Facts
These cockatoos have specialized hinge-like jaws capable of exerting immense pressure to crack open hard seed pods and tear apart dead tree branches in search of beetle larvae.
Condition Notes
Excellent condition with intact barbs, bright coloration, minimal fading, and no visible parasitic damage or physical breakage.
