A detachment of parrots as a kind of detachment of birds

1.Appearancerepresentatives of the order of parrots

Lengthfrom 9.5 cm to 1 m

Plumage small, rather rare. Most parrots are very brightly colored, with the predominant color usually being a bright grassy green. It is especially characteristic that brightly colored fields are sharply delimited one from another, and their colors are often complementary to the colors of the spectrum (green and purple, bluish purple and light yellow, etc.). Young parrots are usually colored the same way.

Wings large, pointed, flight feathers, with strong shafts and wide webs, usually 20, twelve-feather tail. The flight is fast, but usually over a short distance.

Skull parrots are distinguished by their width, the mandibular bones are very high and long, often extending behind the back of the head. The brain is relatively large, good memory and onomatopoeic ability are characteristic (vocal muscles are well developed)

Head in parrots it is large with a large hooked beak, similar to that of feathered predators, but taller and thicker.

Beak the height of the beak at the base is more than twice its width, and sometimes even exceeds its length. Strongly bent beak, connected to the skull and movably, with a sharp ridge and short wax beak at the base, similar to that of birds of prey. The lateral margins of the beak are usually with blunt, strong dentate projections on either side, which correspond to two deep notches on the margins of the mandible. The mandible is short and wide. Parrots can hammer on very hard fruits with their beak, when climbing they cling to branches with their beak (The main feature of the parrot's beak is that it serves not only for getting and chopping food, but also as an organ of locomotion. Figuratively speaking, the parrot's beak is its third The leg hooks its hook-beak on a twig - freed the legs, pulled up the torso, grabbed the next step with movable fingers, then again threw the hook-beak higher. at the same time, they can hold a fruit or a nut in their beak and eat on the go.)

Legs rather short, thick, feathered up to the heel. The 1st and 4th toes are turned back, so that the parrots not only cover branches well with their paws, but can bring food to the beak with their paws. The nails are strongly curved, but rather weak.The very short metatarsal is covered with plates in a grid pattern.

Tongue short, thick and fleshy, sometimes endowed with numerous filiform papillae. The coccygeal gland is sometimes absent.

Vertebrae opisthocele type.

Crest the sternum is high.

Bow poorly developed, often completely absent. The clavicle is short

Stomach double (ferrous and real). There is no gallbladder and no blind appendage of the intestine. The pancreas is double.

2.Lifestyle

Mostly arboreal birds, live in forests, less often in open spaces, few species penetrate high into the mountains. They often keep in flocks. With rare exceptions (kakapo) are diurnal.

Herbivorous, the main food - fruits and seeds of plants, spreading seeds, promote the spread of plants. Loria parrots feed mainly on pollen and nectar, being pollinators of a number of species, in particular, coconut palm, hibiscus and other tropical crops. Crops and orchards are sometimes affected. On occasion, they are ready to feast on animal food - insects and their larvae, worms. Kea also eat carrion, some individuals are even capable of killing adult sheep, but the frequency of such cases is low.

3.Spread

They inhabit the subtropics and tropics, most numerous in the Australian faunal area (the likely center of the origin of the order). Also distributed in southeast Asia, India, West Africa, South America and Central America.

Although parrots are considered by many to be inhabitants of warmer regions, they are also found in more severe areas. So, birds of this order live in the south of New Zealand. The yellow-fronted thick-billed parrot is found in the Andes at an altitude of over 4000 m. And on the subantarctic island of Macquarie, the jumping parrot previously lived.

4.Reproduction

They nest in hollows, termite mounds, in burrows, some on the ground, Argentine parrots (Myiopsitta) build colonial nests on trees. Monogamous. In a clutch there are 1-12 (usually 2-5) eggs. The majority is incubated by a female. Chicks hatch naked and blind, the parents feed them with belching from the goiter.

5.Classification

Currently, there are two families: parrots and cockatoos. The cockatoo family was previously a subfamily. Some taxonomists distinguish the subfamilies of Loriaceae and Nestoria into separate families. There are between 316 and 350 species in these two families. 27 species and 14 subspecies in the IUCN Red List.

Content

Young parrots adapt well to the new environment and are quickly tamed. These are playful and gentle parrots that do not require close attention from the owner. The average life expectancy is up to 30 years (on average 15-20 years).

Classification

The species includes 3 subspecies.

  • Brown-headed long-winged parrotPoicephalus cryptoxanthus cryptoxanthus (W. Peters, 1854) - nominal subspecies. Lives in Swaziland, South Africa, in the south-east of Zimbabwe and the south of Mozambique.
  • Tanganyika brown-headed long-winged parrotPoicephalus cryptoxanthus tanganyikae Bowen, 1930 - head with a marsh tinge, the ear area is more gray, the back is lighter than that of the nominal subspecies. Lives in the south of Kenya, north and north-east of Mozambique, south of Mali and Tanzania.
  • Zanzibar brown-headed parrotPoicephalus cryptoxanthus zanzibaricus - larger than the nominal subspecies, body length 23 cm, wing - 165-170 mm. Lives on the islands of Zanzibar and Pemba. Is on the verge of extinction.
