A parrot corella small and friendly - some of the best pets for bird lovers. They are very smart and calm, and it’s nice to mess with them, and they become attached to people, and they can live quite a long time, in ideal conditions, up to 25 years. They live in nature only in Australia, but in captivity they are kept almost everywhere.

Origin of view and description

Photo: Corella Parrot

The first parrot-like appeared about 55-60 million years ago - after the extinction that occurred at the end of the Cretaceous. Then the majority of the organisms that inhabited the planet disappeared, and, as always after such disasters, the surviving species began to change and separate to fill the vacant ecological niches.

The earliest petrified remains of parrots were found in Europe - in those days its climate was tropical and perfectly suited for these birds. But modern parrots did not come from their European line - it is considered completely extinct, but from another branch.

How the development of the parrot-like has so far been established is not clear enough, although as more and more fossils are found, the picture becomes more complete - it is interesting that all the early finds are exclusively in the northern hemisphere, although modern parrots live mainly in the southern.

It was established that the part of the brain due to which parrots can imitate other people's sounds - for example, human speech, appeared about 30 million years ago. Strictly speaking, before the parrots themselves - about 23-25 ​​million years have passed since the appearance of the first modern species.

These fossils can already be unambiguously identified as corresponding to modern cockatoo - presumably the oldest surviving parrot species. Most of the others occurred much later. It is the cockatoo family that belongs to the genus and species of Corella. A scientific description was obtained by him in 1792, made by his British zoologist R. Kerr. The name of the species in Latin is Nymphicus hollandicus.

Appearance and features

Corella is not a large parrot, it reaches 30-35 centimeters in length, with half being a tail. It weighs from 80 to 150 grams. The tail generally stands out - it is long and pointed. Another sign is a high crest, it can be raised or lowered, it depends on the mood of the bird.

The plumage is brighter in males. Their head and crest are painted in yellow tones, orange spots stand out on the cheeks, and the body and tail are olive with gray. In females, both the head and the tuft are gray, like the body itself, but it is darker, especially from below - the tone can reach brown.

The spots on their cheeks are not orange, but brown. They are also distinguished by pale yellow spots and stripes on the fly and tail feathers - they are absent in males. The beak is short. Young parrots all look like females, therefore it is rather difficult to identify males.

Only closer to the year after the birth of Corella, they are similar in color to adults. Until then, males can only be identified by behavior: they are usually more active, louder - they like to sing and knock on the cage, and they grow faster. Females are calm.

The color described above, which the corals had in nature, is described in captivity, many others are bred, for example, pets of white and pearl color, black, mottled black and gray, and others are common.

Interesting fact: These parrots like to fly, and therefore, when kept in captivity, they must either be released from the cage so that they can fly around the apartment, or placed in a spacious cage so that they do it right inside.

Where does the Corella live?

In nature, they live only on one continent - Australia, whose climate is ideal for them, and there are relatively few predators for whom these small parrots serve as prey. Departing home corals on other continents are not adapted to life in nature and die.

First of all, this applies to those pets that were kept in the temperate zone - they are very demanding on the climate and are not able to survive even autumn or spring cold, not to mention winter. But even if they fly free in a warm climate, they are quickly caught by birds of prey.

In Australia, they can hardly be found off the coast: they prefer to live in the interior of the continent in an arid climate. However, it is not so rare to settle near the shores of lakes or rivers. But most often they live in grassy steppes, on large bushes, trees, cliffs overgrown with vegetation. They are found in semi-deserts.

They like space and open countryside, therefore they do not go deep into the forests, but they can also settle on the edges of eucalyptus groves. If the year turned out to be dry, they are collected near the remaining water bodies. Many Korell live in captivity, where they actively breed. They like to keep these parrots in North America, and in Europe, and in Russia, you can meet them in Asian countries. There are so many of them in captivity that it is already difficult to say where there are more of them - in nature or in humans.

What eats the corella?

The diet of this parrot in nature includes:

  • seeds;
  • cereals;
  • fruits;
  • nectar;
  • insects.

In the wild, they prefer to feed on seeds or fruits of fruit trees, and also do not mind eating eucalyptus nectar - when these trees bloom, you can find many Corelli on them. They settle near the source of water, because they often need to quench their thirst. Sometimes they can act as a pest: if agricultural land is nearby, flocks of Corellus hover over them and peck grains or fruits. Because with farmers often do not get along. In addition to vegetation, they also need protein food - they catch and eat various insects.

In captivity, the cockatiel is fed mainly with grain, but it is important that the parrot's diet be balanced in protein, fat and carbohydrate content, contain a number of vitamins, and finally, the pet should not be overfed - 40 grams of food is enough for a day. Usually the bird is fed mainly with grain mixtures or sprouted grain, but a little green vegetation should be added to them. For example, celery, spinach, corn, dandelion and tree branches - spruce, pine, lime, birch are useful. Also, Corella can feast on the kidneys, nuts.

Fruits with vegetables are an essential part of the Corelli menu. Almost any one suits them: apples, pears, pineapples, bananas, peaches, cherries, watermelons, citrus fruits, berries from raspberries and wild strawberries to rose hips and mountain ash. Vegetables are also suitable for almost all of those grown in our gardens: cucumber, carrots, beets, turnips, zucchini, eggplant, peas, pumpkin, tomato.

It is worth giving only one type of vegetables at a time, but within a month it is better if the diet of the bird is varied - so it will receive more different vitamins. It is advisable to hang bird chalk in the cage, and add food intended for parrots to the food. Finally, she needs to be given some meat, milk, cottage cheese or eggs. In addition to eggs, you can feed Corella cookies, but it should be borne in mind that you can’t give dishes from your own table: sometimes parrots eat them with appetite, and then it turns out that it is harmful to them. A pet may even die if there is something harmful to it among the ingredients.

Now you know how to feed the cockatiel parrots. Let’s see how these birds live in the wild.

Features of character and lifestyle

They are tamed quickly, and after they get used to people, they usually become attached to them and become real pets, adoring affection and care. If they feel them, then in captivity they do not feel sad and breed well. Even wild corals of people are not afraid of much: if they are scared, they can fly up for a while or move to a neighboring tree, and when they see that a person or animal does not show aggression towards them, they return. This sometimes fails them: some predators are accustomed to lull their vigilance, and then attack.

In nature, these parrots often roam. Usually fly over a short distance, but in a few years can cover a significant part of the mainland. Surprisingly adroit: they can quickly move on the ground or climb tree branches, and often use this skill, even if it seems that it is faster to reach the destination on wings.

For the flight, several groups of Corellas living close to each other are united at once. The spectacle turns out to be beautiful: immediately 100-150 parrots rises into the sky, and, unlike large birds, they fly without a strict formation except for a wedge, usually the leader who chooses the direction stands out only in front, and after it everyone just flies freely.

Interesting fact: If the parrot was brought directly from the tropics, first you need to put it in a separate room for a month. During this time, he acclimatizes, and it becomes clear that he has no infections. If you immediately hold it together with other pets, then they can become infected.

Social structure and reproduction

Flocking birds - live in groups, they can contain a very different number of correlates, from a dozen in the smallest, to hundreds or more in the largest. A little more than a hundred Corelli - a threshold value, after which the pack becomes difficult to feed, and it is divided into several. In poorer areas, this value may be lower, and then separation occurs when the flock grows to 40-60 parrots. Sometimes, the corals can even live in small families of only a few individuals in each - but usually dozens of such families immediately occupy trees in direct visibility from each other, so that all of them can be considered as one group.

The breeding time for Corellas begins with the beginning of the rainy season, because the feed becomes larger. If the year turned out to be dry, then they do not breed at all. For nests, they choose voids between thick branches of old or even completely dried trees. In the clutch of 3-8 eggs that need to be incubated for three weeks - both parents alternately do this.

Only the appeared chicks have no feathers at all, only a yellow fluff, and they only fledge in a month. After hatching, the parents feed and protect them, and continue to do so even after they learn to fly and leave the nest - because they remain in the pack, and the parents know their own. The guardianship continues until the moment when young corals reach adult sizes and have their own children. The nestlings leave the nest a month and a half after birth, after which their parents immediately make the second clutch - usually the first occurs in October, and the second in January.

This is the most stressful time for them - you must first hatch the eggs, and then feed the next chicks, and at the same time continue to take care of the previous ones. Although their nests are high in nature, when kept in captivity, the nesting house can also be hung at a low height. It should be quite spacious - 40 cm high and 30 wide. The bottom is covered with sawdust - they need to be put more. It is important that the room is warm and light, and feed should be given more at this time, otherwise the masonry will not be done.

Natural enemies of Corell

There are not many predators in Australia, but this is more true of land - many local birds even chose to walk rather than fly. There are still many dangers in the sky for such small birds as the cockatiels: they are primarily hunted by birds of prey, such as the black kite and the whistle-kite, the tackle, and the brown hawk.

Parrots are significantly inferior to birds of prey in flight speed and are not able to escape from them, if they have already outlined their prey. They are also inferior in the severity of feelings, because they can only rely on mass - a single Corella very quickly becomes the prey of a predator, it is neither able to defend itself nor fly away.

In a large flock of parrots scatter in all directions, the predator grabs one and this is usually limited to. At the same time, Corelli can not be called fearful: they usually sit on branches of trees or bushes, open for attack, they can even go down, where they are vulnerable to land predators. Those, too, would like to feast on them, because catching a Corell is much easier than more careful birds. People also sometimes take advantage of the serenity of these parrots: they hunt for them in order to captive and then sell, or for the sake of meat - even if it is a little, but it is tasty, and getting to this bird is very simple.

The hunters just come up, trying not to scare the Corella - sometimes she, even seeing them, stays in place and allows herself to be captured. And even if it takes off, it may soon return - because of this nature, many Corelli suffer, but thanks to him, they make good pets.

Interesting fact: If usually corals do not differ in timidity, then they become very careful near water bodies - there they face many dangers, and therefore they never sit down to drink water. Instead, they descend vertically directly to the water, swallow quickly and immediately take off again. Usually they need several calls, after which they immediately fly away from the pond.

Population and species status

In nature, the corals are quite numerous and belong to species that are not threatened with extinction - therefore, their numbers are not calculated. But it cannot be said that there are more of them - they are facing quite a lot of dangers, so that the number of these parrots, even with their rather fast breeding, remains at about the same level.

At least the fact that the average life expectancy of wild Corelli is much less than manual ones indicates a large number of threats in nature, in the first case it is 8-10 years, and in the second 15-20 years.

Populations in nature are threatened by the following adversities:

  • farmers exterminate them because they harm the fields;
  • many parrots die due to chemicals in the water;
  • they are hunted to sell or eat;
  • if the bird becomes sick or weak for another reason, it will quickly become a prey of a predator;
  • Forest fires are a common cause of death.

All these factors regulate the number of corellas in nature. So far, most of their habitat is little affected by humans, and therefore the population is not in danger, but as they are developed, these parrots may be in jeopardy - however, this will not happen in the coming decades.

Interesting fact: Corell can be taught to speak, but quite difficult. To do this, you need to buy them very small, and begin training immediately. It will take a long time to repeat the same words or short phrases, and they memorize a little, but they can imitate not only a voice, but also a phone ring, door creak and other sounds.

A parrot corella not just as popular as pets - they are gullible birds that are easy to learn and get used to people. Keeping them is also relatively simple and not expensive, but they are always ready to make up a company and love human attention. Therefore, anyone who wants to have a parrot should think about a pet - Corella.
