Red-tailed Black-Cockatoo

The Red-tailed Black Cockatoo, also known as Banksian- or Banks' Black Cockatoo, is a majestic avian native to the vast landscapes of Australia. The adult males are particularly striking, adorned with a pair of vivid red panels on their tails, which are the hallmark of the species. This cockatoo is more prevalent in the drier regions of the continent and is recognized by five subspecies, each with variations primarily in beak size.

Identification Tips

Males of this species are cloaked in an alluring black plumage, with a pronounced crest of elongated feathers sprouting from the forehead and crown. Their bills are a dark grey, complementing their overall dark appearance. The tail is black, save for the distinctive red panels that give the species its name. Females, on the other hand, are also black but are graced with yellow-orange stripes in the tail and chest, and a mosaic of yellow to red spots on the cheeks and wings. Their bills are a paler horn color, and their underparts are finely barred with yellow over a black base.

Habitat

The Red-tailed Black Cockatoo is typically found in eucalyptus woodlands or along watercourses, where it thrives among the towering trees.

Distribution

This species is widespread across the drier parts of Australia, with a more isolated presence in the south. It is abundant in the northern half of the country, where it has been known to congregate in large flocks.

Behaviour

These cockatoos are diurnal and known for their raucous calls. They can often be seen soaring high in the sky in small flocks, sometimes in the company of other cockatoo species. They exhibit seasonal movements in various parts of Australia, often following food sources.

Song & Calls

The Red-tailed Black Cockatoo's contact call is a rolling metallic sound that carries over long distances. Its alarm call is notably sharp, and displaying males produce a sequence of soft growling followed by a repetitive vocalization.

Breeding

The breeding display of the male involves puffing up crest and cheek feathers, singing, and a dramatic jump to flash red tail feathers at the female. Breeding typically occurs from May to September, with the exception of the South-eastern subspecies, which nests during the summer months.

Similar Species

The Glossy Black Cockatoo is the closest relative to the Red-tailed Black Cockatoo, with both species exhibiting significant sexual dimorphism and unique juvenile calls.

Diet and Feeding

The diet of the Red-tailed Black Cockatoo is predominantly eucalyptus seeds, but it also includes seeds and nuts from a variety of native and introduced plants, as well as berries, fruits, and insects.

Conservation Status

The Red-tailed Black Cockatoo is protected under Australian law and is listed internationally under Appendix II of CITES. However, some subspecies, such as the South-eastern Red-tailed Black Cockatoo, are under threat and subject to conservation efforts.
