The mulga parrot (Psephotellus varius) is endemic to arid scrublands and lightly timbered grasslands in the interior of southern Australia. The male mulga parrot is multicolored, from which the older common name of many-coloured parrot is derived.
The mulga parrot was given its current scientific name of Psephotellus varius by American zoologist Austin Hobart Clark in 1910, after its name Psephotus multicolor was ruled invalid as the original combination (Psittacus multicolor) had been used for another species. [3] Gregory Mathews proposed the name Psephotus dulciei in 1911 for the same reason, [4] unaware of Clark's proposal, which was published earlier and hence had priority. [5]
Mathews described two additional subspecies of mulga parrot in 1912: P. varius rosinae, from a specimen collected from Yorke Peninsula, noting that it had less red on the abdomen and its upper breast was a darker green, and P. varius exsul from a specimen from Mount Magnet in Western Australia, reporting it had a more blue than green color overall, particularly on the cheeks. [6] In 1917, he revised his classification, noting that he had assumed the type collection came from New South Wales but was now made aware that Brown's original specimen came from the Eyre Peninsula on the Spencer Gulf. He added P. varius ethelae from a collection from the Macdonnell Ranges, noting it had all over paler plumage, and renamed the New South Wales form P. varius orientalis, noting its brighter plumage and more prominent red color on the abdomen. [5]
In 1941, Herbert Condon recognised subspecies varius and orientalis, but conceded evidence was lacking in confirming the other two. [7]
In 1955, British evolutionary biologist Arthur Cain reviewed various described subspecies and found none were valid. [8]
Cain concluded in 1955 that within the genus Psephotus the mulga parrot was more closely related to the golden-shouldered parrot than to the red-rumped parrot. [8]
A 2011 genetic study including nuclear and mitochondrial DNA found that the mulga parrot was closely related to the red-capped parrot, the two lineages having diverged in the Miocene. The combined lineage itself diverging from one giving rise to the hooded and golden-shouldered parrots. [9]
A 2018 genetic analysis of specimens across the mulga parrot's range found that there were two lineages that had diverged around 402,000 years ago and recently expanded. The Flinders Ranges and Eyre Peninsula appear to have been the barrier between the two lineages. Preliminary investigation into physical characteristics that might distinguish them suggested that the red patch on the abdomen was possibly brighter and more extensive in the eastern population. McElroy and colleagues agreed the two populations were distinct enough to be recognised as subspecies, however it is unclear to which group the type specimen belongs to. [10]
John Gould called this bird "many-coloured parakeet" or "many-coloured parrot", a term used during the 19th century. The RAOU proposed "mulga parrot" in 1926. [11] Other common names include various parrot and varied parrot. [12]
A 2015 study of museum specimens found that the bill surface area of male mulga parrots had increased by 10.7% between 1871 and 2008. This is consistent with the hypothesis of Allen's rule, where appendages are larger in warmer climates to assist with heat loss. [13]
The Mulga Parrot measures about 27–32 cm (10.5–12.5 in) in length with a 30–42 cm (12–16.5 in) wingspan, and it weighs 50–60 g (1.8–2.1 oz), the mulga parrot is a medium-sized parrot of slim build and long tail. The species is sexually dimorphic, the sexes differing markedly in plumage. [14] The male mulga parrot is multicolored, from which the alternate common name many-coloured parrot is derived. It is a bright green overall, with a bluish tinge on the neck and above the eye, and paler on the breast. The rump is light green. The forehead is yellow and there is a red patch on the back of the head. The lower belly and thighs are yellowish marked with orange-red and the wings greenish apart from the yellow median wing coverts and blue outer webs of primaries. The long tail is an assortment of colours: the two long central feathers are dark blue tinged with green, the outer feathers are blue shading to white and there is some red on the upper tail coverts. Its bill is a blue-grey edged with black, and iris is brown. The female is duller overall, with an olive-brown head and chest, duller yellow forehead and red patch on the back of the head, and pale green belly, and more brown-grey bill. It sometimes also has a red shoulder. [15] [12] [16]
The species ranges across the drier interior of the Australian continent, from Western New South Wales from Collarenebri, West Wyalong and Griffith westwards through the northwestern tip of Victoria and across South Australia and into the drier central regions of Western Australia west to the Wheatbelt and north to the Pilbara. [12] The mulga parrot is generally encountered in pairs in arid grassland and mulga scrubland. [16]
Breeding season is anywhere from July to December or after rainfall, with one or occasionally two broods raised depending on rainfall. A hollow in a tree is utilised for nesting, and a clutch of four to six white eggs measuring 22 x 18 mm is laid. [17] Incubation takes 18 to 21 days and is done by the female alone, the male feeding her while she is on the nest. [18]
The paradise parrot was a colourful medium-sized parrot native to the grassy woodlands extending across the Queensland and New South Wales border area of eastern Australia. Once moderately common within its fairly restricted range, the last live bird was seen in 1927. Extensive and sustained searches in the years since then have failed to produce any reliable evidence of it, and it is the only Australian parrot recorded as disappearing and presumed extinct.
Platycercinae is a subfamily of birds belonging to the family Psittaculidae that inhabit Oceania. It consists of two tribes, the ground parrots and allies (Pezoporini) and the many species of broad-tailed parrot (Platycercini).
A broad-tailed parrot is any of about 35–40 species belonging to the tribe Platycercini. The members of the tribe are small to medium in size, and all are native to Australasia, Australia in particular, but also New Zealand, New Caledonia, and nearby islands.
The red-rumped parrot, also known as the red-backed parrot or grass parrot, is a common bird of south-eastern Australia, particularly in the Murray-Darling Basin.
The crimson rosella is a parrot native to eastern and south eastern Australia which has been introduced to New Zealand and Norfolk Island. It is commonly found in, but not restricted to, mountain forests and gardens. The species as it now stands has subsumed two former separate species, the yellow rosella and the Adelaide rosella. Molecular studies show one of the three red-coloured races, P. e. nigrescens, is genetically more distinct.
The Moluccan eclectus is a parrot native to the Maluku Islands (Moluccas). It is unusual in the parrot family for its extreme sexual dimorphism of the colours of the plumage; the male having a mostly bright emerald green plumage and the female a mostly bright red and purple/blue plumage. Joseph Forshaw, in his book Parrots of the World, noted that the first European ornithologists to see eclectus parrots thought they were of two distinct species. Large populations of this parrot remain, and they are sometimes considered pests for eating fruit off trees. Some populations restricted to relatively small islands are comparably rare. Their bright feathers are also used by native tribespeople in New Guinea as decorations.
The eastern bluebonnet, also known as the greater bluebonnet, is an Australian parrot, one of two species in the genus Northiella. It was originally included in the genus Psephotus but due to distinctive physical and behavioural differences was reclassified into its own genus in 1994 by ornithologists and taxonomists Christidis and Boles. The bluebonnet is a medium-sized inland parrot commonly found in the interior of southeastern and central-southern Australia. It is adapted to life in semi-arid regions but can also flourish in regions of medium rainfall towards the eastern and southern extremities of its range.
Rosellas are in a genus that consists of six species and nineteen subspecies. These colourful parrots from Australia are in the genus Platycercus. Platycercus means "broad-tailed" or "flat-tailed", reflecting a feature common to the rosellas and other members of the broad-tailed parrot tribe. Their diet is mainly seeds and fruit.
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.
Psephotellus is a genus of medium sized Australian parrots. Four species found across the country are recognised, one is presumed to have become extinct.
The hooded parrot is a species of parrot native to the Northern Territory in Australia. It is found in savannah and open woodland and is one of two extant species in its genus that breed in termite mounds. It has declined from much of its original range.
The Moluccan king parrot is a parrot endemic to Peleng Island, Maluku, and West Papua in Indonesia. It is sometimes referred to as the Ambon king parrot or Amboina king parrot, but this is potentially misleading, as it is found on numerous other islands than Ambon. The male and female are similar in appearance, with a predominantly red head and underparts, green wings, and blue back and tail. Six subspecies are recognised, but only a few of these are regular in aviculture. In the wild, it inhabits rainforests and feeds on fruits, berries, seeds and buds.
The western rosella, or moyadong, is a species of parrot endemic to southwestern Australia. The head and underparts are bright red, and the back is mottled black; a yellow patch at the cheek distinguishes it from others of the genus Platycercus. Adults of the species exhibit sexual dimorphism with the females duller overall; juveniles lack the striking colours of mature birds and the characteristic patterning is not as easily distinguished. Their communication call is a softly delivered pink-pink sound, and much of their behaviour is comparatively unobtrusive. Their habitat is in eucalypt forests and woodlands, where they often remain unobserved until they appear to feed on seeds at nearby cleared areas.
The rock parrot is a species of grass parrot native to Australia. Described by John Gould in 1841, it is a small parrot 22 to 24 cm long and weighing 50–60 g with predominantly olive-brown upperparts and more yellowish underparts. Its head is olive with light blue forecheeks and lores, and a dark blue frontal band line across the crown with lighter blue above and below. The sexes are similar in appearance, although the female tends to have a duller frontal band and less blue on the face. Two subspecies are recognised.
The green rosella or Tasmanian rosella is a species of parrot native to Tasmania and Bass Strait islands. It was described by the German naturalist Johann Friedrich Gmelin in 1788, and named on the mistaken assumption it came from New Caledonia. At 14.5 in (37 cm) long it is the largest species of the rosella genus, Platycercus. Two subspecies are recognised. The green rosella's underparts, neck and head are yellow, with a red band above the beak and violet-blue cheeks. The back is mostly black and green, and its long tail blue and green. The sexes have similar plumage, except the female has duller yellow plumage and more prominent red markings, as well as a smaller beak. Juvenile and immature birds have predominantly green plumage.
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.
The blue-winged parrot, also known as the blue-banded parakeet or blue-banded grass-parakeet, is a small parrot found in Tasmania and southeast mainland Australia. It is partly migratory, with populations of blue-winged parrots travelling to Tasmania for the summer. The parrot is sexually dimorphic – the males have more blue on the wings and a two-toned blue frontal band on the head, while females are duller and have more green on the wings and a wingbar. Both sexes have predominantly olive-green plumage. Predominantly a feeder on the ground, the blue-winged parrot mainly eats seeds of grasses. It adapts readily to captivity.
The splendid fairywren is a passerine bird in the Australasian wren family, Maluridae. It is also known simply as the splendid wren or more colloquially in Western Australia as the blue wren. The splendid fairywren is found across much of the Australian continent from central-western New South Wales and southwestern Queensland over to coastal Western Australia. It inhabits predominantly arid and semi-arid regions. Exhibiting a high degree of sexual dimorphism, the male in breeding plumage is a small, long-tailed bird of predominantly bright blue and black colouration. Non-breeding males, females and juveniles are predominantly grey-brown in colour; this gave the early impression that males were polygamous as all dull-coloured birds were taken for females. It comprises several similar all-blue and black subspecies that were originally considered separate species.
Alisterus is a genus of medium-sized Australasian parrots, comprising the Australian king parrot, the Papuan king parrot and the Moluccan king parrot. The three species are respectively found in eastern Australia, Papua, the Moluccas and other Indonesian islands. Predominantly of red and green plumage, the long-tailed parrots are related to the genera Aprosmictus and Polytelis.
The Naretha bluebonnet or Naretha parrot is a bird found in a remote and arid region of Australia. It is one of two species in the genus Northiella, and was first recorded in 1921 in Central Australia.
