![]() ![]() Females have black and gold barring in their tail feathers, gold spots on their plumage and gold fringing on their chest feathers. In males, the band is solid red when they reach maturity at three to four years old. Red-tailed Black Cockatoos – (Calyptorhynchus banksii)Īs the name suggests, red-tailed black cockatoos are large beautiful black cockatoos with a red band in their tail feathers. They are playful, raucous, mischievous and quite destructive. Corellas have diluted yellow in their tail and under their wings. The exception is the eastern long-billed corella with a reddish area visible on the neck below their bill. Apart from being visible around the eyes, the crest colour and head feather colour is hidden unless the crest raises or the head feathers are ruffled. In addition, there are small amounts of deep salmon pink at the base of the crest and head feathers and around the eyes. Description Common to all CorellasĪll three corellas species are white birds with a characteristic patch of bare blue-grey skin around the eyes leading to the name ‘bare eyed’ cockatoo sometimes given to Corellas. All other corella species are classified as secure and declared agricultural pests in some areas due to their damage to crops. Due to conservation efforts, it has recovered significantly and was removed from the threatened list in 2012. It suffered a dramatic decline in numbers due to poisoning and shooting late last century and by the 1940s had dropped to less than 100 birds. The Muir’s corella is classified as vulnerable. There are two subspecies of western corellas, with Butler’s corellas ( Cacatua pastinator butleri) occupying the northern and central Wheatbelt and Muir’s corellas ( Cacatua pastinator pastinator) inhabiting an area in the south-west of Western Australia in the Lake Muir area. Little corellas are widespread throughout Australia, whereas long-billed corellas inhabit Australia’s south-east region from southern New South Wales to South Australia. There are two sub-species of western corella and four sub-species of the little corella. There are three types of corellas in Australia, the long-billed corella ( Cacatua tenuirostris), little corella ( Cacatua sanguinea), and the western corella ( Cacatua pastinator), also known as the western long-billed corella. ![]() They are intelligent with powerful and destructive beaks. Large, noisy flocks inhabit many eastern Australian suburban areas and are considered pests in some areas. They also have diffused yellow in their tail and under their wings. There is also an introduced population of the eastern species in the Perth region.Īs the name suggests, sulphur-crested cockatoos are white birds with a bright yellow crest. fitzroyi, extends from the north of Western Australia to the Gulf of Carpentaria. Cacatua g galerita inhabits large areas of eastern Australia from Cape York to Tasmania. ( Cacatua galerita)ĭespite their association with Australia, there are four sub-species of sulphur-crested cockatoos, and only two are Australian. Sulphur-crested cockatoos and corellas are as Australian as kangaroos and koalas and the species most commonly referred to as ‘cockies’. White cockatoos are among the most iconic of Australia’s avian species and belong to the genus Cacatua. However, for this article, and to benefit a non-scientific audience, I will take a less scientific approach to describe the different cockatoo types. The different genera are sometimes re-classified by the scientists studying them. For example, the sulphur-crested cockatoo belongs to the genus Cacatua, so the scientific name is Cacatua galerita (Genus + species). The species and their respective subspecies are divided into genera based on their physical characteristics. In addition, cockatoos are less colourful than other parrot families, predominantly black, white, and grey with smaller amounts of red, yellow, and pink. They vary tremendously in size, colour and plumage, but one characteristic common to all is a prominent movable crest and curved hooked bills. Australia is home to 12 species with additional subspecies. Taxonomy of Cockatoos in AustraliaĬockatoos are parrots who belong to the family ‘Cacatuidae’ in the Psittaciformes’ order with two other families, true parrots (Psittacoidea) and large New Zealand parrots (Strigopoidea). But what type of bird is an Australian cockatoo? I have witnessed heated discussions online about whether a particular bird is a galah, or a corella, or a ‘cocky’, suggesting that many people don’t understand that both are cockatoos, along with several other Australian species. ![]() The term ‘cockies’, a shortened version of ‘cockatoos’, is commonly used in Australia to refer to several bird species. ![]()
