The plum-headed parakeet (Psittacula cyanocephala) is a species of parakeet in the family Psittacidae. It is endemic to the Indian Subcontinent and was once thought to be conspecific with the blossom-headed parakeet (P. roseata) before being elevated to a full species. Plum-headed parakeets are found in flocks, the males having a pinkish purple head and the females, a grey head. They fly swiftly with twists and turns accompanied by their distinctive calls.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the plum-headed parakeet in his Ornithologie based on a specimen collected in India. He used the French name Le perruche a teste bleu and the Latin name Psittaca cyanocephalos. [2] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. [3] When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. [3] One of these was the plum-headed parakeet. Linnaeus included a terse description, coined the binomial name Psittacus cyanocephalus and cited Brisson's work. [4] The specific name cyanocephalus/cyanocephala combines the Ancient Greek words kuanos "dark-blue" and -kephalos "-headed". [5] This species is now placed in the genus Psittacula which was introduced by the French naturalist Georges Cuvier in 1800. [6]
The plum-headed parakeet is a mainly green parrot, 33 cm long with a tail up to 22 cm. The male has a red head which shades to purple-blue on the back of the crown, nape and cheeks, while the female has a blueish-gray head. There is a narrow black neck collar with verdigris below on the nape and a black chin stripe that extends from the lower mandible. There is a red shoulder patch and the rump and tail are bluish-green, the latter tipped white. The upper mandible is orangish-yellow, and the lower mandible is dark. The female has a dull bluish grey head and lacks the black and verdigris collar, which is replaced by yellow. The upper-mandible is corn-yellow and there is no black chin stripe or red shoulder patch. Immature birds have a green head and both mandibles are yellowish. The dark head is acquired after a year. [7] [8] [9] The delicate bluish red appearance resembling the bloom of a peach is produced by a combination of blue from the optical effects produced by the rami of the feather and a red pigment in the barbules. [10]
Some authors have considered the species to have two subspecies, the nominate from peninsular India (type locality restricted to Gingee [11] ) and the population from the foothills of the Himalayas as bengalensis on the basis of the colour of the head in the male which is more red and less blue. [9] Newer works consider the species to be monotypic. [7]
The different head colour and the white tip to the tail distinguish this species from the similar blossom-headed parakeet (P. roseata). The shoulder patch is maroon coloured and the shorter tail is tipped yellow in P. roseata. [7]
A supposed species of parakeet, the so-called intermediate parakeet Psittacula intermedia is thought to be a hybrid of this and the slaty-headed parakeet (P. himalayana). [12]
The plum-headed parakeet is a bird of forest and open woodland, even in city gardens. They are found from the foothills of the Himalayas south to Sri Lanka. They are not found in the dry regions of western India. [9] They are sometimes kept as pets and escaped birds have been noted in New York, [13] Florida [14] and in some places in the Middle East. [15]
The plum-headed parakeet is a gregarious and noisy species with a range of raucous calls. The usual flight and contact call is tuink? repeated now and then. The flight is swift, and the bird often twists and turns rapidly. It makes local movements, driven mainly by the availability of the fruit and blossoms which make up its diet. They feed on grains, fruits, the fleshy petals of flowers (Salmalia, Butea) and sometimes raid agricultural fields and orchards. The breeding season in India is mainly from December to April, and July to August in Sri Lanka. Courtship includes bill rubbing and courtship feeding. [16] It nests in holes, chiselled out by the pair, in tree trunks, and lays 4–6 white eggs. The female appears to be solely responsible for incubation and feeding. They roost communally. In captivity, it can learn to mimic beeps and short whistling tunes, and can talk very well. [9]
Neoaulobia psittaculae, a quill mite, has been described from the species. [17] A species of Haemoproteus , H. handai, has been described from blood samples from the plum-headed parakeet. [18]
Ctesias of Cnidus, a 5th-century BC Greek physician to the emperor Artaxerxes II, who ruled the Achaemenid Empire, accompanied Artaxerxes on his 401 BC campaign against his brother Cyrus the Younger. He was author of the lost Indica, a description of India which he wrote based on his experience in Persia and information he gathered from Persian accounts. [19] Fragments of the Indica were preserved by Photius of Constantinople in his Bibliotheca in the 9th century AD; one of these has been identified as describing Psittacula cyanocephala and its abilities as a talking bird. [20] It is likely Ctesias saw the bird himself, with an Indian handler; though his description could also apply to Psittacula roseata , that species is native to areas far further east and is much less likely candidate in Greater Iran. [20] [21] In his summary of Ctesias, Photius wrote: [20] [21]
[Ctesias says] there is a bird called the bittakos which has a human voice, is capable of speech, and grows to the size of a falcon. It has a crimson face and a black beard and is dark blue as far as the neck … like cinnabar. It can converse like a human in Indian but if taught Greek, it can also speak Greek. | καὶ περὶ τοῦ ὀρνέου τοῦ βυττάκου, ὅτι γλῶσσαν ἀνθρωπίνην ἔχει καὶ φωνήν, μέγεθος μὲν ὅσον ἱέραξ, πορφύρεον δὲ πρόσωπον, καὶ πώγωνα φέρει μέλανα. Αὐτὸ δὲ κυάνεόν ἐστιν ὡς τὸν τράχηλον ὥσπερ κιννάβαρι. Διαλέγεσθαι δὲ αὐτὸ ὥσπερ ἄνθρωπον ἰνδιστί, ἂν δὲ ἑλληνιστὶ μάθῃ, καὶ ἑλληνιστί. |
Newton's parakeet, also known as the Rodrigues parakeet or Rodrigues ring-necked parakeet, is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues in the western Indian Ocean. Several of its features diverged from related species, indicating long-term isolation on Rodrigues and subsequent adaptation. The rose-ringed parakeet of the same genus is a close relative and probable ancestor. Newton's parakeet may itself have been ancestral to the endemic parakeets of nearby Mauritius and Réunion.
The blossom-headed parakeet is a parrot in the family Psittaculidae.
The Alexandrine parakeet, also known as the Alexandrine parrot, is a medium-sized parrot in the genus Psittacula of the family Psittaculidae, native to South Asia and Southeast Asia. It is named after Alexander the Great, who transported numerous birds from Punjab to various European and Mediterranean countries and regions, where they were prized by the royalty, nobility and warlords.
Layard's parakeet is a parrot which is a resident endemic breeder in Sri Lanka. The common name of this bird commemorates the British naturalist Edgar Leopold Layard; his first wife, Barbara Anne Calthrop, whom he married in 1845, is commemorated in the specific epithet.
Members of the parrot genus Psittacula or Afro-Asian ring-necked parrots, as they are commonly known in aviculture, originate from Africa to South-East Asia. It is a widespread group with a clear concentration of species in south Asia, but also with representatives in Africa and the islands of the Indian Ocean. This is the only genus of parrot which has the majority of its species in continental Asia. Of all the extant species only Psittacula calthropae, Psittacula caniceps and Psittacula echo do not have a representative subspecies in any part of mainland continental Asia. The rose-ringed parakeet, Psittacula krameri, is one of the most widely distributed of all parrots.
The orange-winged amazon, also known locally as orange-winged parrot and loro guaro, is a large amazon parrot. It is a resident breeding bird in tropical South America, from Colombia, Trinidad and Tobago south to Peru, Bolivia and central Brazil. Its habitat is forest and semi-open country. Although common, it is persecuted as an agricultural pest and by capture for the pet trade. It is also hunted as a food source. Introduced breeding populations have been reported in Puerto Rico and Tenerife in the Canary Islands.
The slaty-headed parakeet is the only psittacid species to exhibit altitudinal migration. The species' range extends from Pakistan, to Western Himalayas in India through Nepal and Bhutan and up to the Eastern Himalayas in the northeastern Indian state of Arunachal Pradesh. They descend to the valleys in winter, approximately during the last week of October.
The blue-winged parakeet, also known as the Malabar parakeet is a species of parakeet endemic to the Western Ghats of southern India. Found in small flocks, they fly rapidly in forest clearings while making screeching calls that differ from those of other parakeet species within their distribution range. Their long blue tails tipped in yellow and the dark wings with blue contrast with the dull grey of their head and body. Adult males and females can be easily told apart from the colour of their beak.
The echo parakeet is a species of parrot endemic to the Mascarene Islands of Mauritius and formerly Réunion. It is the only living native parrot of the Mascarene Islands; all others have become extinct due to human activity. Two subspecies have been recognised, the extinct Réunion parakeet and the living echo parakeet, sometimes known as the Mauritius parakeet. The relationship between the two populations was historically unclear, but a 2015 DNA study determined them to be subspecies of the same species by comparing the DNA of echo parakeets with a single skin thought to be from a Réunion parakeet, but it has also been suggested they did not constitute different subspecies. As it was named first, the binomial name of the Réunion parakeet is used for the species; the Réunion subspecies thereby became P. eques eques, while the Mauritius subspecies became P. eques echo. Their closest relative was the extinct Newton's parakeet of Rodrigues, and the three are grouped among the subspecies of the rose-ringed parakeet of Asia and Africa.
The Nicobar parakeet, also known as the Blyth's parakeet, is a parrot in the genus Psittacula, endemic to the Nicobar Islands of the Indian Ocean. It is one of the largest parakeets, measuring 56 to 60 cm from the top of the head to the tip of the tail and weighing about 224 g.
Lord Derby's parakeet, also known as Derbyan parakeet, is a parrot species, which is confined to a small pocket of moist evergreen forest in the hills and mountains of the Indian states of Arunachal Pradesh and Assam, and adjoining parts of Tibet, Sichuan and Yunnan in China. The species suffers from cutting of old trees and poaching for the illegal wildlife trade. In 2011, its status was updated from least concern to near threatened on the IUCN Red List. The adult male and female are easily distinguished because they have different beak colours and slightly different plumage.
The long-tailed parakeet or Burung Bayan Nuri in Malay is a parakeet endemic to the regions of Andaman and Nicobar islands, Sumatra, Borneo and Peninsular Malaysia. It is allopatric with the congener, the Red-breasted parakeet, Psittacula alexandri, except in the Andaman islands where they occur together.
The Seychelles parakeet or Seychelles Island parrot is an extinct species of parrot that was endemic to the Seychelles in the Indian Ocean. It was scientifically named Palaeornis wardi by the British ornithologist Edward Newton in 1867, and the specific name honours the British civil commissioner Swinburne Ward who procured the specimens that formed the basis for the description. It was found on the islands of Mahé, Silhouette, and possibly Praslin. Ten skin specimens exist today, but no skeletons. Though the species was later moved to the genus Psittacula, genetic studies have led some researchers to suggest it should belong in a reinstated Palaeornis along with the closely related Alexandrine parakeet (P. eupatria) of Asia.
Psittaculini is a tribe of parrots of the family Psittaculidae. The subdivisions within the tribe are controversial.
The Mascarene parrot or mascarin is an extinct species of parrot that was endemic to the Mascarene island of Réunion in the western Indian Ocean. The taxonomic relationships of this species have been subject to debate; it has historically been grouped with either the Psittaculini parrots or the vasa parrots, with the latest genetic study favouring the former group.
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 intermediate parakeet or Rothschild's parakeet was a kind of parakeet reported from the sub-Himalayan region of India and was described on the basis of about seven undated specimens. Similar individuals have been noted in captivity and the type specimen is now believed to be a hybrid between Psittacula himalayana and Psittacula cyanocephala. More recent captive specimens that appeared similar were found to be hybrids produced by crosses between Psittacula krameri and Psittacula cyanocephala. An analysis of the characters of the specimens suggests that the originally described P. intermedia was a hybrid between P. cyanocephala x P. himalayana.
The Mascarene grey parakeet, Mauritius grey parrot, or Thirioux's grey parrot, is an extinct species of parrot which was endemic to the Mascarene Islands of Mauritius and Réunion in the western Indian Ocean. It has been classified as a member of the tribe Psittaculini, along with other parrots from the Islands.
The parrot subfamily Psittaculinae consists of three tribes: the Polytelini with three genera, the Psittaculini or Asian psittacines, and the pygmy parrots of the Micropsittini tribe.
