Baudin's black cockatoo (Zanda baudinii), also known as Baudin's cockatoo or the long-billed black cockatoo, is a species of genus Zanda found in southwest Australia. The epithet commemorates the French explorer Nicolas Baudin. It has a short crest on the top of its head, and the plumage is mostly greyish black. It has prominent white cheek patches and a white tail band. The body feathers are edged with white giving a scalloped appearance. Adult males have a dark grey beak and pink eye-rings. Adult females have a bone coloured beak, grey eye-rings and ear patches that are paler than those of the males.

Taxonomy and naming

Baudin's black cockatoo was depicted in 1832 by the English artist Edward Lear in his Illustrations of the Family of Psittacidae, or Parrots from a specimen owned by the naturalist Benjamin Leadbeater. Lear used the common name "Baudin's cockatoo" and coined the binomial name Calyptorhynchus baudinii. [2] The common name and specific epithet commemorate the French explorer Nicolas Baudin, who led an expedition to Australia in 1801-1804. [3] The species is now placed in the genus Zanda that was introduced in 1913 by the Australian born ornithologist Gregory Mathews. [4] [5]

Carnaby's black cockatoo (Zanda latirostris) and Baudin's black cockatoo were previously classified as the same species. [6] Common names include Baudin's black cockatoo or long-billed black cockatoo. [7]

The two Western Australian white-tailed black cockatoo species, the short-billed Carnaby's black cockatoo and this long-billed Baudin's black cockatoo, together with the yellow-tailed black cockatoo Zanda funerea of eastern Australia are allied in the genus Zanda. Previously this genus was considered a subgenus of Calyptorhynchus , with the red-tailed black cockatoo and glossy black cockatoos forming another subgenus, Calyptorhynchus, but due to a deep genetic divergence between the two groups they are now widely treated as separate genera. [8] The two genera differ in tail colour, head pattern, juvenile food begging calls and the degree of sexual dimorphism. Males and females of Calyptorhynchus sensu stricto have markedly different plumage, whereas those of Zanda have similar plumage. [9]

The three species of the genus Zanda have been variously considered as two, then as a single species for many years. In a 1979 paper, Australian ornithologist Denis Saunders highlighted the similarity between the short-billed and the southern race xanthanotus of the yellow-tailed and treated them as a single species with the long-billed as a distinct species. He proposed that Western Australia had been colonised on two separate occasions, once by a common ancestor of all three forms (which became the long-billed black cockatoo), and later by what has become the short-billed black cockatoo. [10] However, an analysis of protein allozymes published in 1984 revealed the two Western Australian forms to be more closely related to each other than to the yellow-tailed, [11] and the consensus since then has been to treat them as three separate species. [9]

Description

Baudin's black cockatoo is about 56 cm (22 in) long. It is mostly dark-grey with narrow vague light-grey scalloping, which is produced by narrow pale-grey margins at the tip of dark-grey feathers. It has a crest of short feathers on its head, and it has whitish patches of feathers that cover its ears. Its lateral tail feathers are white with black tips, and the central tail feathers are all black. The irises are dark brown and the legs are brown-grey. Its beak is longer and narrower than that of the closely related and similar Carnaby's black cockatoo. [12]

The adult male has a dark grey beak and pink eye-rings. The adult female has a bone coloured beak, grey eye-rings, and its ear patches are paler than that of the male. Juveniles have a bone coloured beak, grey eye-rings, and have less white in the tail feathers. [12]

One individual had reached an age of 47 years by 1996. [13]

Distribution and habitat

The Baudin's black cockatoo is one of two species of white-tailed black cockatoo endemic to south-western Australia which were only separated taxonomically in 1948. It is closely associated with moist, heavily forested areas dominated by marri Corymbia calophylla and is threatened by habitat destruction.

Conservation

The range of threats to the declining population, estimated to be between ten and fifteen thousand remaining individuals, has been since 2021 listed with the conservation status of Critically Endangered by IUCN. [1]

The bird is part of an annual census, the Great Cocky Count, that has been held every year since 2009 to track the population change of Baudin's and other black cockatoos. [14]

Sites identified by BirdLife International as being important for Baudin's black cockatoo conservation are Araluen-Wungong, Gidgegannup, Jalbarragup, Mundaring-Kalamunda, North Dandalup, the Stirling Range and The Lakes. [15]

The cockatiel, also known as the weero/weiro or quarrion, is a medium-sized parrot that is a member of its own branch of the cockatoo family endemic to Australia. They are prized as household exotic bird pets and companion parrots throughout the world and are relatively easy to breed compared to other parrots. As a caged bird, cockatiels are second in popularity only to the budgerigar.

The yellow-tailed black cockatoo is a large cockatoo native to the south-east of Australia measuring 55–65 cm (22–26 in) in length. It has a short crest on the top of its head. Its plumage is mostly brownish black and it has prominent yellow cheek patches and a yellow tail band. The body feathers are edged with yellow giving a scalloped appearance. The adult male has a black beak and pinkish-red eye-rings, and the female has a bone-coloured beak and grey eye-rings. In flight, yellow-tailed black cockatoos flap deeply and slowly, with a peculiar heavy fluid motion. Their loud, wailing calls carry for long distances. The yellow-tailed black cockatoo is found in temperate forests and forested areas across south and central eastern Queensland to southeastern South Australia, including a very small population persisting in the Eyre Peninsula. Two subspecies are recognised, although Tasmanian and southern mainland populations of the southern subspecies xanthanotus may be distinct enough from each other to bring the total to three. Birds of subspecies funereus have longer wings and tails and darker plumage overall, while those of xanthanotus have more prominent scalloping. The subspecies whiteae is found south of Victoria to the East of South Australia and is smaller in size.

The red-tailed black cockatoo also known as Banksian- or Banks' black cockatoo, is a large black cockatoo native to Australia. Adult males have a characteristic pair of bright red panels on the tail that gives the species its name. It is more common in the drier parts of the continent. Five subspecies are recognised, differing chiefly in beak size. 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.

The red-capped parrot is a species of broad-tailed parrot native to southwestern Australia. It was described by Heinrich Kuhl in 1820, with no subspecies recognised. It has long been classified in its own genus owing to its distinctive elongated beak, though genetic analysis shows that it lies within the lineage of the Psephotellus parrots and that its closest relative is the mulga parrot. Not easily confused with other parrot species, it has a bright crimson crown, green-yellow cheeks, and a distinctive long bill. The wings, back, and long tail are dark green, and the underparts are purple-blue. The adult female is very similar though sometimes slightly duller than the male; her key distinguishing feature is a white stripe on the wing under-surface. Juveniles are predominantly green.

<span class="mw-page-title-main">Glossy black cockatoo</span> Species of cockatoo from Australia

The glossy black cockatoo, is the smallest member of the subfamily Calyptorhynchinae found in eastern Australia. Adult glossy black cockatoos may reach 50 cm (19.5 in) in length. They are sexually dimorphic. Males are blackish brown, except for their prominent sub-terminal red tail bands; the females are dark brownish with idiosyncratic yellow marking around the neck and prominent sub-terminal tail band of red with black bars. Three subspecies have been recognised, although this has been recently challenged, with a detailed morphological analysis by Saunders and Pickup 2023 finding there is cline in body dimensions over the latitudinal range of the species, with the birds from the north of the range smaller than the birds in the south. Saunders and Pickup argued that with no differentiation in bill morphology, little difference in genetic makeup, no differences in plumage pattern or colour, and no differences in diet, there is no justification in subdividing the species.

Carnaby's black cockatoo, also known as the short-billed black cockatoo, is a large black cockatoo endemic to southwest Australia. It was described in 1948 by naturalist Ivan Carnaby. Measuring 53–58 cm (21–23 in) in length, it has a short crest on the top of its head. Its plumage is mostly greyish black, and it has prominent white cheek patches and a white tail band. The body feathers are edged with white giving a scalloped appearance. Adult males have a dark grey beak and pink eye-rings. Adult females have a bone-coloured beak, grey eye-rings and ear patches that are paler than those of the males.

<i>Calyptorhynchus</i> Genus of cockatoos

Described by French naturalist Anselme Gaëtan Desmarest in 1826, the genus Calyptorhynchus has two species of cockatoos. They are all mostly black in colour, and the taxa may be differentiated partly by size and partly by small areas of red, grey, and yellow plumage, especially in the tail feathers. Studies based on the mitochondrial DNA 12S gene fragment suggested that other sexually dichromatic species, the gang-gang cockatoo and the cockatiel may be the closest living relatives of Calyptorhynchus. However, subsequent studies, including more genes confirm the morphological taxonomy with the gang-gang cockatoo most closely related to the galah, within the white cockatoo group, and with the cockatiel as a third distinct subfamily of cockatoos.

<span class="mw-page-title-main">Northern rosella</span> Parrot native to northern Australia

The northern rosella, formerly known as Brown's rosella or the smutty rosella, is a species of parrot native to northern Australia, ranging from the Gulf of Carpentaria and Arnhem Land to the Kimberley. It was described by Heinrich Kuhl in 1820, and two subspecies are recognised. The species is unusually coloured for a rosella, with a dark head and neck with pale cheeks—predominantly white in the subspecies from the Northern Territory and blue in the Western Australian subspecies hillii. The northern rosella's mantle and scapulars are black with fine yellow scallops, while its back, rump and underparts are pale yellow with fine black scallops. The long tail is blue-green, and the wings are black and blue-violet. The sexes have similar plumage, while females and younger birds are generally duller with occasional spots of red.

Black cockatoo is a general descriptive term for cockatoos that are mainly black and may include:

<i>Zanda</i> (bird) Genus of birds

The genus Zanda has three species of cockatoos. They are all mostly black in colour, and the taxa may be differentiated partly by size and partly by small areas of red, grey, and yellow plumage, especially in the tail feathers.
