For many years, the species was referred to as Calyptorhynchus magnificus, proposed by Gregory Mathews in 1927 as Shaw's name had predated Latham's 1790 description. Narrowly predating Latham, English naturalist George Shaw described Psittacus magnificus from a specimen collected somewhere in the Port Jackson (now Sydney) region. The red-tailed black cockatoo also has the distinction of being the first bird from Eastern Australia illustrated by a European, as a female, presumably collected at Endeavour River in north Queensland, was sketched by Banks' draughtsman Sydney Parkinson in 1770. The species complex was first described by the ornithologist John Latham in 1790 as Psittacus banksii, commemorating English botanist Sir Joseph Banks. Of the black cockatoos, the red-tailed is the most adaptable to aviculture, although black cockatoos are much rarer and much more expensive in aviculture outside Australia. Populations in southeastern Australia are threatened by deforestation and other habitat alterations. They are seed eaters and cavity nesters, and as such depend on trees with fairly large diameters, generally Eucalyptus. In the more northerly parts of the country, these cockatoos are commonly seen in large flocks. The species is usually found in eucalyptus woodlands, or along water courses. Although the more northerly subspecies are widespread, the two southern subspecies, the forest red-tailed black cockatoo and the south-eastern red-tailed black cockatoo are under threat. Five subspecies are recognised, differing chiefly in beak size. It is more common in the drier parts of the continent. Adult males have a characteristic pair of bright red panels on the tail that gives the species its name. Retain Glossy Black-Cockatoo food trees and hollow-bearing trees and extend their habitat by planting more.The red-tailed black cockatoo ( Calyptorhynchus banksii) also known as Banksian- or Banks' black cockatoo, is a large black cockatoo native to Australia.Join a Bushcare group or community planting and plant more native vegetation, including Glossy Black-Cockatoo food trees.When nibbling on food, they only ever use their left foot to hold the cones.The waterhole is usually nothing more than a puddle in a cleared area. At the end of each day after feeding, the Glossy Black-Cockatoo must stop at a waterhole to drink.To successfully raise a chick, they need to find large trees (around 200 years old) which have hollows big enough for them to nest and raise their chick.Glossy Black-Cockatoos only lay one egg every two years.Redland City Council is an active partner of The Glossy Black Conservancy and endeavours to enhance Glossy Black-Cockatoo habitat and manage environmental pests throughout the Redlands to minimise their impact on native ecosystems and endangered animals such as Glossy Black-Cockatoos. It is an offence to injure, harass, hurt or interfere with Glossy Black-Cockatoos and their breeding places. Glossy Black-Cockatoos are protected under the Nature Conservation Act 1992. Loss of large trees with large hollows for nesting.They have been known to occasionally feed on Casuarina cristata and C. The diet of the Glossy Black-Cockatoo is mainly restricted to the seeds of only two subspecies of She-oaks in south east Queensland the Forest She-oak ( Allocasuarina torulosa) and the Black She-Oak ( A. These cockatoos are highly selective in terms of both the trees and the cones on which they choose to forage. They are also seen feeding occasionally on the mainland. In the Redlands, you will find Glossy Black-Cockatoos living predominantly on North Stradbroke Island and the Southern Moreton Bay Islands. lathami halmalurinus has an isolated population in South Australia on Kangaroo Island. lathami erebus is mainly found in central eastern Queensland, from the Dawson-Mackenzie basin to Paluma and C. The Glossy Black-Cockatoo family includes three subspecies that are differentiated according to beak and wing morphology, with non-overlapping ranges – Calyptorhynchus lathami lathami has a core population in south-eastern Australia, C. The tail panels are also different: bright red for the male and reddish-yellow barred with black for the female.
The male’s head is brownish in colour whereas the female has irregular patches of yellow over the head and neck. Glossy Black-Cockatoo’s have distinct differences in appearance between the adult male and female birds. The Glossy Black-Cockatoo is the smallest of the Australian Black-Cockatoos and is characterised by its very large beak and very small crest.
