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.

Contents

The other two Asian genera, Loriculus and Psittinus are represented by only two species each, which occur in the mainland part of Asia. The majority of the Loriculus species occur on islands. Moreover, since Loriculus is spread across both sides of the Wallace Line it can be considered more Australasian than Asian. These parrots mostly have green plumage, with adults having coloured heads. The bill is stout, and the tail is long and graduated.

Etymology

The genus name Psittacula is a diminutive of the Latin word psittacus meaning "parrot".

Taxonomy

The genus Psittacula was introduced in 1800 by the French naturalist Georges Cuvier. [1] The type species was designated in 1923 by Gregory Mathews as the red-breasted parakeet. [2] [3] The name of the genus is a diminutive of the Latin word psittacus for a "parrot". [4]

The genus includes 16 species, of which three are extinct. [5]

Phylogeny of the genus Psittacula based on a study by Michael Braun and coworkers published in 2019. [6]

Genetic evidence has found that the genus Psittacula is likely paraphyletic; for example, genetic analysis has supported merging short-tailed parrots of the genus Tanygnathus, Psittinus, and the extinct Mascarinus with Psittacula. [7] A revised classification was proposed by Michael Braun and coworkers in 2019 that splits the genus Psittacula into multiple monophyletic genera in order to preserve Tanygnathus, Psittinus, and Mascarinus as distinct genera. After the proposed split, the only remaining species in Psittacula sensu stricto are P. derbiana, P. caniceps, and P. alexandri. [6] This is also the taxonomic system followed by the IUCN Red List and BirdLife International. The list of split or monophyletic genera and species (and any of their allied species) is displayed below:

The extinct Mascarene grey parrot (P. bensoni) was not sampled in the study and has not been reclassified to Psittacula sensu lato by the IUCN or BirdLife, so it is still classified in Lophopsittacus under this taxonomy and with the common name Mauritius grey parrot. [8] The Nicobar parrot(P. caniceps) was also not sampled but kept in Psittacula by the authorities that incorporated this taxonomy. [9]

The study has also found that the rose-ringed and red-breasted parrots are likely paraphyletic species themselves, and thus need to be split into multiple species. [6]

Hypothetical extinct species

The Rothschild's or intermediate parakeet P. intermedia, found in northern India, was formerly considered a mystery, as only very few specimens were known. It has since been demonstrated to be a hybrid between the slaty-headed parrot P. himalayana and the plum-headed parrot P. cyanocephala. [10] [11]

The taxonomy of the Réunion parakeet P. eques is also confusing. Extinct since 1770, little evidence even exists of the bird's existence. A study skin had been discovered at the Royal Museum of Scotland, explicitly referencing a book description of the Réunion birds. It is known from other descriptions, as well as illustrations of which it is unknown whether they were drawn from live or stuffed specimens. This may be the only material proof of these birds' existence. Taxonomists are unsure if the birds were a distinct species, or conspecific with the echo parakeet, although genetic analysis supports it being a subspecies of the echo parakeet.

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 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.

<span class="mw-page-title-main">Echo parakeet</span> Species of parrot endemic to Mauritius

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.

<span class="mw-page-title-main">Seychelles parakeet</span> Extinct bird species once endemic to Seychelles

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.

<span class="mw-page-title-main">Rodrigues parrot</span> Extinct species of parrot that was endemic to Rodrigues

The Rodrigues parrot or Leguat's parrot is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues. The species is known from subfossil bones and from mentions in contemporary accounts. It is unclear to which other species it is most closely related, but it is classified as a member of the tribe Psittaculini, along with other Mascarene parrots. The Rodrigues parrot bore similarities to the broad-billed parrot of Mauritius, and may have been related. Two additional species have been assigned to its genus, based on descriptions of parrots from the other Mascarene islands, but their identities and validity have been debated.

<i>Tanygnathus</i> Genus of birds

Tanygnathus is a genus of parrots in the Psittaculini tribe, of the superfamily of Psittacoidea.

<i>Psittinus</i> Genus of birds

Psittinus is a genus of parrot in the family Psittaculidae. It was formerly considered to include a single species, the blue-rumped parrot, but the Simeulue parrot was split as a distinct species by the IOC in 2021. A 2019 genetic analysis found that the genus Psittacula is paraphyletic with respect to Psittinus, indicating that Psittacula may have to be split into different genera in order to maintain Psittinus as a distinct genus.

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.
