Long-tailed Parakeet (Bayan)























The Long-tailed Parakeet, Psittacula longicauda, is also known as Malaccan Red-cheeked Parakeet, Malayan Red-cheeked Parakeet, Pink-cheeked Parakeet or Bayan Nuriis.
Sub-species
Distribution / Range:
This parrot is native to the regions of Andaman islands, Nicobar islands, Sumatra, Borneo and Peninsular Malaysia (including Singapore), Indonesian island of Nias as well as Bangka and Anambas Islands.
They can be found in forests, swamps and mangrove areas, partly cleared areas and oil palm plantations. They are also seen visiting suburban gardens with tall vegetation.
They usually occur in groups of up to 20 birds; however, large gatherings of 800 or more birds have been observed in favored feeding areas. Seasonal migrations are likely.
These are restless birds that are constantly on move. They climb quickly around in branches, moving quickly from tree to tree. Though they are usually well camouflaged in the green foliage, but their continuous screeching cannot be missed. They tend to feed soon after sunrise and resume foraging in the later afternoons.
Status:
Much of their natural habitat has been destroyed and this parrot is frequently trapped for the cage-bird trade, resulting in a marked decline - but this species is still common in localized areas. In general, however, these parakeets are near-threatened and the survival of the various subspecies is unknown.
They usually form groups of up to 20 birds, although at times up to 800 parakeets can congregate, particularly at coastal roost sites. These parrots appear to be nomadic. They are conspicuous because of their continuous harsh, strident screeches given from treetops and in flight.
Description:
The Long-tailed Parakeet averages 16.5 inches (40 to 42 cm) in length. The wing length is about 142 - 155 mm and the tail is about 154 - 270 mm long.
Adult Male: The general plumage is green. The throat, breast and abdomen are greenish-yellow; and the lores (the regions between the eyes and bill on the side of a bird's head) are bluish-black. The crown is a darker green, and the sides to head and nape are rose-red. There is a black stripe to the cheeks. The upper back is yellowish washed bluish-grey. The lower back is pale blue. The under wing-coverts are yellowish. The upper and under tail-coverts as well as the thighs are pale green. The middle tail-feathers are blue with pale tips and the outer feathers are green. The upper beak is red and the lower beak is brownish-black. The irises are whitish-yellow, and the feet are grey.
Females have a green nape. The stripe to her cheeks is dark green, and the upper cheeks are dull orange-red. Her tail-feathers are much shorter, and the upper and lower mandible are brownish-black.
Young birds have a green head variably interspersed with orange-red. The tail feathers are shorter, and both the upper and lower beak are brown. Young males have a bluish tinge on the lower back and some young males may have a reddish tinge to the upper beak. Immature birds attain their adult plumage when they are about 30 months old.
Mutations:
Lutino and other colorations, believed to be mutations, have been observed both in the wild and in captivity.
Breeding / Nesting:
The breeding season commences in February and goes on until about July. During the courtship display, the male bows before hen, making regurgitating and circular movements with head and touching bill of hen.
These parrots mostly nest in hollow branches or holes in dead trees and occasionally will nest in living trees. The nest is lined with pieces of bark and chewed wood. In the natural habitat, the average clutch consists of 2 to 3 eggs each measuring 30.6 x 24.7 mm.
Aviculture:
This is a medium-noisy to noisy parakeet. It's initially very shy and is slow to grow confiding with their care taker. These parakeets don't bathe often, but will occasionally choose to perch in rain. They enjoy gnawing fresh twigs.
Captive breeding is rarely achieved. The main problems are the difficulty of matching compatible pairs up as these parakeets may not accept a mate that they themselves have not chosen and even if pairs are breeding, it is very difficult to keep the chicks alive. Sudden mortalities without discernible cause have been reported - possibly resulting from stress. Some may refuse to eat. Occasional aggression by hen towards the cock has been observed. Additionally, these delicate parrots are difficult to acclimatize. Newly imported birds are susceptible to cold and wet conditions. During the acclimatization period, they should not be exposed to temperatures of less than 24°C and at no time below 10°C.
The average clutch size consists of 2 - 4 eggs laid at daily intervals and incubated for about 23 days. The young fledge 7 weeks after hatching and are independent 2 weeks later.
Accommodation:
These parakeets need spacious aviaries and are rather active if they have space to move around. A planted outside flight of the following dimensions OR LARGER is recommended: 3 x 1 x 2 m with adjoining sheltered area (heated if necessary to maintain a comfortable temperature). It's important to place the aviary in a quiet and sheltered location.
Provide a roosting box (22 x 22 x 60 cm) at all times.
Diet / Feeding:
Natural diet consists of fruits (Pandanus, Carica papaya, Dryobalan-ops sp.), seeds, flowers (Acacia) and leaf buds.
Insects and their larvae may also be part of their daily diet; whether these parrots actively seek them out is unknown, but they may be incidentally ingested while foraging on fruits and flowers. These parakeets are also considered a crop pest as they cause considerable damage to oil palm plantations in their natural range.
Captive Diet: An organic, good-quality dry food mix should be provided, that may include safflower and sunflower seeds, buckwheat, various millets, canary grass seed, oats and hemp; millet spray (also sprouted). A large portion of their diet should consists of a variety of fruit (apple, pear, fig, grapefruit); greenfood and vegetables (carrot, capsicum, cucumber). Sprouted seeds should be fed daily.
During the breeding season, eggfood, biscuit and sprouted seeds should be provided to the parents to help them raise the young.
Sprouted or germinated seeds are usually more easily accepted by "seed addicts" than fresh fruits and vegetables.
Sprouted seeds are healthier as the sprouting changes and enhances the nutritional quality and value of seeds and grains. Sprouted seeds are lower in fat, as the process of sprouting utilizes the fat in the seed to start the growing process - thus reducing the fat stored in the seeds.
Sprouted seeds will help balance your bird’s diet by adding a nutritious supply of high in vegetable proteins, vitamins, minerals, enzymes, and chlorophyll.
Soaked and germinated "oil" seeds, like niger and rape seeds, are rich in protein and carbohydrates; while "starch" seeds, such as canary and millets, are rich in carbohydrates, but lower in protein.
It is in invaluable food at all times; however, it is especially important for breeding or molting birds. Sprouted seeds also serve as a great rearing and weaning food as the softened shell is easier to break by chicks and gets them used to the texture of seeds.
If you have access to the food items that are part of their natural diet (listed above), that may increase your chances of maintaining a healthy breeding flock.
Call / Vocalization:
This parrot emits rapidly repeated shrill cries during flight.
Pet Quality / Training and Behavioral Guidance:
As these parakeets are so rare, experts prefer any captive birds to be placed into a well-managed breeding program. If for some reason, an individual is unsuitable for breeding and you are considering it for your aviary or as pet, you may want to consider the following.
Ringneck parrots are less demanding than other parrot species, which makes them an excellent choice for someone who wants to "step up" from an easy-going and easy-care cockatiel or budgie.
Consistent training and behavioral guidance from a young age is recommended to ensure potential owners enjoy a bird free of destructive and annoying habits.
Behavioral challenges that ringnecks present include:
Chewing: Any parrot will chew. In nature, they use their beak to "customize" their favorite tree, to enlarge the size of their nest in a tree hollow. Doing this keeps their beaks in good condition. The problem is excessive and undesirable chewing. Undisciplined ringnecks may chew on electric wiring potentially causing house fires. The owner needs to provide plenty of "healthy" chewing opportunities (bird toys, natural wood branches, etc.) and training is necessary to teach a parrot what is "off-limits."
Jealousy / Aggression: The ringneck parrots can be jealous of other family members and pets. They can develop a bond with only one human and refuse to interact with other people, even attacking them in some cases. Although this is a small bird it does not seem to believe so, and will attack larger birds and even dogs if it feels it or its human is threatened. Owners should be cautious in multiple-pet homes. Continuing to socialize the hand reared pet bird from a young age and letting many people handle and interact with it can prevent single-person bonding and allow it to become an excellent family pet.
Noise: They can be noisy - albeit not as noisy as their larger cousins. Not everybody can tolerate the natural call of a ringneck parrot, and even though it can't (or should not) be entirely eliminated, there are ways to discourage screaming / screeching in your pet. Ringnecks are known for their talking and whistling ability, and teaching and encouraging your pet to talk is one way to reduce undesirable screeching in your pet.
