Layard's parakeet (Psittacula calthrapae) 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.
Layard's parakeet is a green parrot, 29 cm long including a tail up to 13 cm. The adult has a bluish-grey head and back, separated by a green collar. There is a broad black chin stripe and the tail is blue tipped yellow. The upper mandible of the male's bill is red and the lower mandible is brown.
The female is similar, but has an all black beak and less green on the face than the male. Immature birds are mainly green, with an orange bill. [2]
Layard's parakeet is a bird of forests, particularly at the edges and in clearings, and also gardens. It is locally common. It undergoes local movements, driven mainly by the availability of the fruit, seeds, buds and blossoms that make up its diet. It is less gregarious than some of its relatives, and is usually in small groups outside the breeding season, when it often feeds with brahminy starlings. Its flight is swift and direct, and the call is a raucous chattering. It nests in holes in large trees, laying 3–4 white eggs.
In Sri Lanka, this bird is knowns as alu girawaඅළු ගිරවා (ash-parrot) in Sinhala. [3] This bird appears on a 50c Sri Lankan postal stamp. [4] Also this bird appears in 500 Sri Lankan rupee bank note (2010 series). [5]
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.
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.
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 Sri Lanka hanging parrot is a small parrot which is a resident endemic breeder in Sri Lanka.
The vernal hanging parrot is a small parrot which is a resident breeder in the Indian subcontinent and some other areas of Southeast Asia. It undergoes local movements, driven mainly by the availability of the fruit, seeds, buds and blossoms that make up its diet. They frequent the banyan tree for the fruit and plantain trees for the nectar from the flowers.
The Sri Lanka hill myna, Ceylon myna or Sri Lanka myna, is a myna, a member of the starling family. This bird is endemic to Sri Lanka.
Legge's flowerpecker or the white-throated flowerpecker, is a small passerine bird. It is an endemic resident breeder in Sri Lanka. It is named after the Australian ornithologist William Vincent Legge.
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 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.
