The Alexandrine parakeet (Psittacula eupatria), also known as the Alexandrine ring-necked parakeet or Alexandrine parrot, is a parrot in the genus Psittacula of the family Psittacidae. 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 nobility, royalty and warlords.[2][3][4]

The Alexandrine parakeet has established feral populations in Spain, England, France, the Netherlands, Belgium, Germany, Bahrain, Qatar, the United Arab Emirates, Iran and Turkey, where it lives alongside feral populations of the rose-ringed parakeet (Psittacula krameri).[1][5][6]

Taxonomy and etymology

Mathurin Jacques Brisson described the Alexandrine parakeet as Psittaca Ginginiana "La Perruche de Gingi" in 1760.[7] Carl Linnaeus described the Alexandrine parakeet in 1766 as Psittacus eupatria, identifying it as the same as Brisson's species.[8]

The genus name Psittacula is a diminutive of the Latin word psittacus meaning "parrot", and the specific name eupatria comes from the Ancient Greek words eu- meaning "well" and patriá meaning "descent".[9][10][11]

Description

Female
Male

The Alexandrine parakeet is one of the largest parakeets, measuring 55 to 62 cm (22 to 24 in) from head to tail and weighing between 200 and 300 g (7.1 and 10.6 oz). It has a wing length averaging 18.9 to 21.5 cm (7.4 to 8.5 in) and a tail length of 21.5 to 35.5 cm (8.5 to 14.0 in).[3][2] It is mainly green with a light blue-grey sheen on the cheeks and nape (back of the neck), and yellowish-green abdomen. The upperside of the middle tail feathers is blueish-green, the upperside of the external tail feathers is green while the underside of the tail feathers is yellow. All Alexandrine parakeets (irrespective of age, gender and/or subspecies) have a maroon or reddish-brown patch at the top of their wing coverts, commonly called a 'shoulder' patch. The shoulder patch is seen in parakeets at their first feathering before fledging. The beak is red with yellow tips.[3][12] The irises are yellowish-white and the periopthalmic rings (bald patches around the eyes) are light grey. The legs are grey except in the P. e. siamensis subspecies, where they are yellowish-grey.[3][12]

Adult alexandrine parakeets are sexually dimorphic, while the young are monomorphic and are similar in appearance to adult females but have shorter tail feathers and duller plumage. Adult males usually have prominent black rings on their neck and large pink bands on their napes, but sometimes only have a narrow blue stripe above their nape bands. Adult parakeets with neither black feathers in their neck nor pink feathers in their nape are females. Adult feathering usually develops between 18 and 30 months of age.[2][3]

Subspecies

Five subspecies of the Alexandrine parakeet are currently recognized. Information on the distribution and plumage differences of the different subspecies is given below.[2][12]

Subspecies Distribution Notes
Nominate Alexandrine parakeet (P. e. eupatria) East India, southwestern India and Sri Lanka. Nominate subspecies
Large Indian parakeet (P. e. nipalensis) Nepal, Bhutan, Northeast India, North India, Central India, Pakistan and eastern Afghanistan. It is larger than the nominate subspecies and the back of the head and cheeks are washed with blue. The nape bands of adult males are broader.
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 top of the head and the nape are more yellow-green and some individuals have a thin blue stripe on the hindneck.
Large Andaman parakeet (P. e. magnirostris) Andaman Islands and Coco Islands. It is slightly larger than the nominate subspecies. It also has a larger beak and brighter shoulder patch. Males have a thin 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. It also has a more red shoulder patch and yellowish face and neck. Males look like P. e. avensis. however the back of the head and nape are washed with blue.

Ecology and behaviour

The Alexandrine parakeet lives in forests, woodlands, agricultural lands and mangrove forests at elevations of up to 900 m (3000 ft). It eats a variety of wild and cultivated seeds, buds, flowers, nectar, fruits and nuts.[2][3]

It lives in small flocks but can form larger groups in areas where food is abundant. It is known to form communal roosts.[2] Its calls are usually harsh and loud. It shrieks loudly when alarmed by predators and flocks often excitedly vocalize together.[2][3]

Breeding

Alexandrine parakeets breed from November to April in their native range. Females lay 2 to 4 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][3]

Conservation

The Alexandrine parakeet is listed as near threatened by the International Union for Conservation of Nature (IUCN) because of its steep population decline due to habitat loss, persecution and excessive capture to cater to the demands of the illegal wildlife trade.[1]

The sale of Alexandrine parakeets is banned in Pakistan, but they can be found being openly sold in the markets of Lahore and Rawalpindi. Their sale is also 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.[13][14]

Cultural depictions

Thailand, Mongolia and Iran have stamps depicting the Alexandrine parakeet.[15][16][17][18]
