Description
The Alexandrine Parakeet is a large Parakeet species measuring 58 cm (23 in) in total length with a wingspan averaging 18.9–21.5 cm (7.5–8.5 in). It is mainly green with a blue-grey sheen on its cheeks and napes, particularly in males. The abdomen is yellowish-green, 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 are all yellow. All Alexandrine Parakeets (irrespective of age, gender and/or sub-species) boldly display a maroon (reddish-brown) patch at the top of their wing coverts (commonly called 'shoulder' patch). The shoulder patch is seen in parakeets at their first feathering before fledging from their nests. The lower and upper mandible are red with yellow tips. The adult's irises are yellowish-white and the periopthalmic rings are light grey. The legs are grey except in the P. e. siamensis (Laos' or Siamese sub-species) where they are yellowish-grey.
The species is dimorphic in adulthood (3 years and older). The immatures are monomorphic and are similar but duller in appearance to that of the adult females. Adult males always show pitch-black neck rings and large pink bands on their napes (commonly called nape bands). Often males only display a little band of blueish-grey above their bold pink nape-bands. Adult females frequently show neck ring shadows that are anywhere between light and dark shades of grey. Females never display true black feathers in their neck-rings. Immatures of either genders are very similar to adult females but as with all genuine parakeet species, the young Alexandrine Parakeets always display shorter middle-tail feathers and thus shorter tails than adults. The adult feathering usually is acquired between 18–30 months of age, but may sometimes show up as young as 12 and/or as old as a full 36 months of age. Consequently, it may be difficult to identify the sex Alexandrine Parakeets by sight with absolute certainty until they are a full 36 months of age.
The young males can be identified as soon as they display one (or more) pitch-black feathers of their neck rings and/or one (or more) pink feathers of their nape bands. Often, the young males develop their neck rings and nape bands in two or sometimes three successive moulting seasons. Adult parakeets with neither pitch-black feathers in their neck rings nor pink feathers in their nape bands are usually females.
The P. e. nipalensis ssp. (Nepalese Alexandrine Parakeet) is the largest of the species measuring 62 cm (24.5 in) in total length with a wingspan averaging between 20–24 cm (8–9.5 in). It is thus recognized as the world's largest genuine Parakeet (short to mid sized Long-Tailed Parrot) species. It looks much like the Nominate sub-species. However, the feathers on the chest and abdomen in both genders display whitish-grey sheens, the cheeks and napes are washed with blue and the adult males display large pink nape bands.
The P. e. magnirostris ssp. (Andaman Island's Alexandrine Parakeet) is slightly larger than the nominate sub-species, displaying a wingspan anywhere between 20–22.5 cm (8–9 in). It looks much like the nominate race. However, the feathers on the chest and abdomen in both genders display whitish-grey sheens. The maroon 'shoulder' patch is of a much redder (or less brownish) colour than of that of the nominate. The beak is larger and more massive. The adult males display large pink nape bands, the blue sheens above the nape-bands are restricted and sometimes absent in some specimens.
The P. e. avensis ssp. (Indo-Burmese Alexandrine Parakeet) is of same size as the nominate species, also measuring 58 cm (23 in), displaying a wingspan averaging anywhere between 19.4–22 cm (7.5–8.5 in) and looks much like the Nominate ssp. However, the top of the head and the nape are of a yellowish-green, the blue sheens are restricted to the cheeks and thus absent in the nape. The adult males display thinner and pinker nape-bands.
The P. e. siamensis ssp. (Laos or Siamese Alexandrine Parakeet) is the smallest of the species, measuring 56 cm (22 in), displaying a wingspan averaging anywhere between 17.9–20.5 cm (7–8 in) and looks much like the Nominate ssp. However, the top of the head and the nape display pale-blue sheens that extends to the crown in some specimens. The cheeks are yellowish-green, the 'shoulder' patch is of a nearly brownless red colour and the legs display a pronounced yellowish shade.
Aviculture
The bird is popular among aviculturists. It is idea for outdoor aviaries and cannot tolerate temperatures less than 5 °C (41 °F). They breed well in aviaries. The parakeet is one of the oldest captive Parakeet species on the Eurasian continent. It gets its name from the legendary Emperor Alexander The Great, who had numerous specimens exported back to various Mediterranean countries by his legionaries. The parakeet has since then been popular among the nobles throughout the Empire's Anatolian, European and Mediterranean countries.
Captivity
It is an active species, likes water (bathing, misting, raining and showering) and readily accepts diverse and/or new foods. It chews vigorously and hence it is important to keep the perch non-toxic without chemical products such as disinfectants, fungicide, insecticides or pesticides. The Alexandrine Parakeet has an average lifespan of 40 years in capitivity and as with all other parakeets, they are among the top mimics.
Natural breeding habits
Breeding season is from November to April in their natural distribution range. Average clutch size is 2–4 eggs measuring 34.0 x 26.9 mm (1 x 1.3 in). The average incubation period is 28 days usually starting with the laying of the second egg. The chicks fledge around seven weeks of age. They are reared for about three weeks and are typically weaned between 12 to 16 weeks of age. They are critically endangered in Pakistan specially in Punjab province. This is mostly due to loss of habitat, like cutting of old tress and excessive poaching of their new born chicks. Although it is officially banned in Pakistan to sell these parrots but they can be found openly being sold in markets of Lahore.
Natural diet
The diet consists of seeds, nuts, fruits, berries, buds, flowers and nectars (Salmalia, Butea, Erythrina, Bassia latifolia). It causes considerable damage to cultures of corn, grains, rice and or chards.
Diet in captivity
A fresh mix (with or without dehydrated fruits and/or vegetables) of various seeds, grains and nuts generally represent the typical basic diet. Cooked and fresh foods, Whole grains and cereals, Edible blossoms and flowers such as Carnations, chamomile, chives, dandelion, daylily, eucalyptus, fruit tree's blossoms, herbs' blossoms, hibiscus, honeysuckle, impatiens, lilac, nasturtiums, pansies, passion flower (passifloræ), roses, sunflowers, tulips, and violets, Fruits with all pits discarded and/or larger seeds such as apple varieties, banana, all berries varieties, all citrus varieties, grapes, kiwi, mango, melons, nectarine, papaya, peach, all pear varieties, plum. Avocado and rhubarb that are reportedly highly intoxicating for all Parrot species. Vegetables, legumes/pulses and commercial greens and weeds such as bok-choi, broccoli, cauliflower leaves, cabbage leaves, chicory, collard greens, dandelion leaves, endives, espadrille, kelp, mustard plant leaves, seaweeds, spirulina and water cress are given. Wild harvested greens and weeds such as Bromus, chickweeds, cocksfoot or orchard grasses, dandelions, dogstooth, elymus, fescues, marram grasses, milk thistles, oats and wild oats, plantain (the weed), poa genus (i.e. Blue, Meadow's, Spear, Tussock grasses) are also given.
