Fate is not always favorable to the representatives of the animal world. To some she turns in front, while to others she pays no attention at all. As a result, we have what we have. Some species of birds and animals are on the verge of complete extinction, and man is to blame for this, uncontrollably interfering with their natural habitat. It is his rash actions that violate the natural balance, thereby causing irreparable harm to the animal world. If we do not change our minds in time and do not take protective measures, then we can say goodbye to some species of birds and animals.
An example is the Chatham petroics, which once densely inhabited the Chatham archipelago of South Zealand. Quite recently, the population of these birds was on the verge of complete extinction, and only thanks to the measures taken by humans, the situation began to slowly stabilize. At the same time, the same person became the reason for the disappearance of petroics. His rash actions led to the fact that only one single bird remained alive. And if not for the efforts of scientists, then we could see this rare bird only in pictures.
What kind of bird is this?
The weight of this crumb is only 25 grams. Moreover, the length of her body is no more than 15 centimeters. The plumage is black. The body is slightly elongated. Females differ from males only in size. They are somewhat smaller.
To save the petroika population from extinction, ornithologists decided to resort to artificial insemination of the surviving female. They put the eggs she laid under another bird, and not without success. Taking the eggs, the scientists provoked the bird to carry them again. Thus, we managed to get several clutches, and to bring out 200 small chicks. In this way, it was possible to preserve the bird population, although it is still at a critical level.
The task is further complicated by the fact that petroika, by its nature, is a monogamous bird, and throughout its life remains faithful to the same partner. In this case, the female makes a clutch once a year. She finds a suitable place in which she equips the nest. As a rule, preference is given to empty hollows, as well as natural shelters, such as crevices in rocks or heaps of stones. Clutch contains no more than three eggs. The female incubates them. The male at this time gets food and feeds the spouse.
Birds feed on insects and their larvae. In the wild, they live no more than four years.
The natural enemies of petroics are predators and humans, who unceremoniously invade their natural habitat. The main reason for the disappearance of birds is agricultural activity. Rats, which destroy birds' nests, eat eggs and chicks, also cause great harm. In such conditions, they cannot survive. Today petrochem is listed in the Red Book, but in order to preserve the population, special programs and responsible decisions are needed.
For the sake of fairness, it must be said that in recent years, the tendency towards the extinction of certain species of animals and birds has begun to increase, and something needs to be done about this. After all, this process cannot pass without a trace for a person. The most important thing is to eradicate cruelty in yourself, and stop recklessly with nature.
