The Alexandrine parakeet (Psittacula eupatria), 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. [2] [3]
The Alexandrine parakeet has established feral populations in Turkey, [4] Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, the United Arab Emirates Iran,and Pakistan where it lives alongside feral populations of its close relative, the rose-ringed parakeet (Psittacula krameri). [1] [2] [5] [6] [7]
The Alexandrine parakeet was first described by French zoologist Mathurin Jacques Brisson as Psittaca Ginginiana or "La Perruche de Gingi" (The Gingi's Parakeet) in 1760; after the town of Gingee in southeastern India, which was a French outpost then. The birds may, however, merely have been held in captivity there. [8] Carl Linnaeus redescribed the Alexandrine parakeet in 1766 as Psittacus eupatria. [9]
The genus name Psittacula is a diminutive of the Latin word psittacus meaning "parrot", and the specific name eupatria (εὖπατριά) is derived from the ancient Greek eu- meaning "well" and patriá meaning "descent". [10] [11] [12]
In 2019, a genetic study revived the genus Palaeornis , formerly viewed as a synonym of the current genus Psittacula . Some organisations – including the IUCN – have accepted the new taxonomy. [1] If this were to be taken into account, this could mean that the Alexandrine parakeet is the only living member of the now-revived genus.
Genetic analysis of the mitochondrial cytochrome b sequences of Psittacula parakeets has shown that the Alexandrine parakeet diverged from the lineage that gave rise to the rose-ringed parakeet (Psittacula krameri) and the Mauritius parakeet (Psittacula eques) about 5 million years ago. [13]
The Alexandrine parakeet is one of the largest parakeets, measuring 56 to 62 cm (22 to 24 in) from the top of the head to the tip of the tail and weighing 200 to 300 g (7.1 to 10.6 oz). The tail measures 28 to 35 cm (11 to 14 in). [2] [14] It is predominantly green with a light blue-grey sheen on the cheeks and nape (back of the neck), yellow-green abdomen, red patch on the shoulders and massive red beak with yellow tips. The upper-side of the tail passes from green at the top to blue further down, and is yellow at the tip. The underside of the tail is yellow. [2] [14] [15]
Adults are sexually dimorphic. Adult males have a black stripe across their lower cheeks and a pink band on their nape. Adult females lack both a black cheek stripe and a pink nape band. The young are similar in appearance to adult females but have shorter tails. [2] [16]
Five subspecies of the Alexandrine parakeet are currently recognized [2] [16]
Subspecies | Distribution | Notes |
---|---|---|
Alexandrine parakeet (P. e. eupatria) [main type-group] | Western India, South India and Sri Lanka. | 'Nominate' subspecies: Main type-(sub)species for the whole group. |
Large Indian parakeet (P. e. nipalensis) | Eastern Afghanistan, Pakistan, North India, Central India, East India, Nepal, and Bhutan. | It is larger than the nominate subspecies, and more greyish-green. The back of the head and cheeks are tinged blue. Adult males have a broader black stripe across the lower cheek. |
Large Burmese parakeet (P. e. avensis) | Northeast India, Bangladesh, and Myanmar. | It has a smaller beak than the nominate subspecies. Males look like P. e. nipalensis, however the neck and underparts are more yellowish and there is a narrow blue stripe on the hindneck. |
Large Andaman parakeet (P. e. magnirostris) | Andaman Islands and Coco Islands. | It is slightly larger than the nominate subspecies, and has a larger beak and brighter shoulder patch. Males have a narrow blue stripe above the nape band. |
Thai rose-ringed parakeet (P. e. siamensis) | Vietnam, Cambodia, Laos, and Thailand. | It is smaller than the nominate subspecies and has a paler shoulder patch. It also has a yellowish face and neck. Males look like P. e. avensis, however the back of the head and nape are tinged blue. |
The Alexandrine parakeet lives in forests, woodlands, agricultural lands and mangrove forests at elevations of up to 900 m (3,000 ft). It eats a variety of wild and cultivated seeds, buds, fruits and nuts. Flocks can cause extensive damage to ripening fruits and grain crops like maize and jowar. It usually lives in small flocks, but forms larger groups in areas where food is abundant or at communal roosts. [2] [15]
The Alexandrine parakeet has a variety of calls, including a ringing trrrieuw, loud kree-aar or keeak, deep klak-klak-klak-klak and resonant gr-aak. Its calls are usually deeper, harsher and more resonant than those of the rose-ringed parakeet. Its voice becomes harsher when alarmed, and it shrieks loudly when mobbing predators. Flocks occasionally excitedly vocalize together. It is known to imitate human speech in captivity. [2] [15] [16] [17]
Alexandrine parakeets breed from November to April in their native range. They usually nest in tree hollows, but sometimes use tree holes excavated by themselves or cracks in buildings. Females lay 2 to 4 white, blunt oval-shaped eggs, measuring 27 to 34 mm (1.1 to 1.3 in). The average incubation period is 24 days. The chicks fledge at about 7 weeks of age, and are dependent on their parents until 3 to 4 months of age. [2] [15]
Alexandrine parakeets are relatively popular pet birds due to their long lifespan in captivity (up to 40 years), [18] playful behaviour and ability to mimic human speech. Alexander the Great is thought to have kept one as a pet. They are one of the most sought-after cage birds in the Indian market. According to CITES trade data, at least 57772 Alexandrine parakeets were imported into countries outside their native range between 1981 and 2014. [1] [3] [5] [19]
Color variants including lutino, albino, and blue are well-established in captivity.
The World Parrot Trust recommends that captive Alexandrine parrots be kept in a metal or welded mesh enclosure of minimum length 4.5 metres (15 ft). [18]
The Alexandrine parakeet is listed as near threatened by the International Union for Conservation of Nature (IUCN) because of its steep population decline in its native range due to habitat loss, persecution and excessive capture to cater to the demands of the illegal wildlife trade. It is sporadic in South India, uncommon in Bangladesh, and declining in North Bengal and certain parts of Sri Lanka. It has suffered the greatest population declines in the Sindh and Punjab provinces of Pakistan, Laos, northwestern and southwestern Cambodia, and Thailand. [1] [20] [21]
The sale of Alexandrine parakeets is not banned in Pakistan, and they can be found being openly sold in the markets of Lahore and Rawalpindi. Their sale is banned in India, and yet they are sold in broad daylight in urban bird markets, suggesting that the Indian government is allocating insufficient resources for their protection. [19] [21]
Sri Lanka, Vietnam, Thailand, Mongolia and Iran have issued postage stamps depicting the Alexandrine parakeet. [22] [23] [24] [25]
A parakeet is any one of many small- to medium-sized species of parrot, in multiple genera, that generally has long tail feathers.
The rose-ringed parakeet, also known as the ringneck parrot or the Kramer parrot, is a medium-sized parrot in the genus Psittacula, of the family Psittacidae. It has disjunct native ranges in Africa and the Indian Subcontinent, and is now introduced into many other parts of the world where feral populations have established themselves and are bred for the exotic pet trade.
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 plum-headed parakeet 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 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.
The blossom-headed parakeet is a parrot in the family Psittaculidae.
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.
Psittacula, also known as Afro-Asian ring-necked parrots, is a genus of parrots from Africa and Southeast 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 Sri Lanka hanging parrot is a small parrot which is a resident endemic breeder in Sri Lanka.
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 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 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 red-breasted parakeet is a parrot native to Southeast Asia. It is among the more widespread species of the genus and is the species which has the most geographical variations. It is easily identified by the large red patch on its breast. An alternative name is the moustached parakeet depending on subspecies. Most of the subspecies are confined to minuscule islands or a cluster of islands in Indonesia. One subspecies occurs in the Andaman islands, and one subspecies occurs in continental Southeast Asia and partly extending to northeastern parts of South Asia along the foothills of the Himalayas. Some of the island races may be threatened by the wild bird trade. The nominate race, which occurs in Java, is close to extinction.
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.
A feral parrot is a parrot that has adapted to life in an ecosystem to which it is not native. The birds are often descended from pets that have escaped or been deliberately released. Many species of parrots are highly social, and like to gather in large flocks. Not all feral parrots are able to adapt to life outside of captivity, although having a pre-existing nearby parrot colony can assist with the adaptation process.
The plain parakeet is a species of bird in subfamily Arinae of the family Psittacidae, the African and New World parrots. It is endemic to Brazil.
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.
Birds of Eden is the world's largest free flight aviary and bird sanctuary, located in Kurland village near Plettenberg Bay in the Western Cape, South Africa. The mesh dome of the sanctuary was built over 2.3 hectares of indigenous forest, and is up to 55 metres (180 ft) above ground level. 1.2 kilometres (0.75 mi) of walkways, about 75% of which are elevated, let visitors see the birds at all levels of the aviary.
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.
