The Burrow bird is a small carnivorous bird, also known as: The Bailuo Bird, The Burrow Head, is a ferocious bird and an important insectivore. Their main feature is that the mouth is large and strong, and the upper mouth has a hook and a missing carving, which is slightly similar to the eagle's beak. Berau has short, rounded wings, usually a convex tail, strong feet and a good hook, fierce sex, and a penchant for eating various insects such as small mammals, birds, lizards, and other active animals. Most inhabit hilly, open woodlands, with cup-shaped nests nested among thorny trees or shrublands. The eggs often have slightly dark brown spots of varying sizes.
Birds of the Berauco family are fierce in temperament and are known as "birds of prey among finches". He often stands on a high place and looks down, waiting for opportunities, catching insects, frogs, lizards, birds and rats, etc., and has the habit of cutting corpses on thorns, sometimes not eating them all, and storing food in this way. Hence the English language also refers to it as "butcher birds", but the Australian butcherbirds are not Berau, but a genus of cracticus that occupies the same ecological niche as them.
Beraugu called it "Eagle". Berau is an important insectivorous bird. Their main feature is that the mouth is large and strong, and the upper mouth has a hook and a missing carving, which is slightly similar to the eagle's beak. The wings are short, rounded, usually convex-tailed. Strong feet and good hooks. Fierce, it eats small animals, birds, lizards and other insects and other active animals. Most of them inhabit hilly and open woodlands. It often perches on the top of the tree, hunts on the ground, and returns to the branches after catching; often hangs the prey on the thorny tree, and with the help of the tree thorn, kills it, tears it up and eats it, so some people call it a butcher bird. The nest is cup-shaped and placed among thorny trees or shrubs. The eggs often have slightly dark brown spots of varying sizes. Most of them are migratory birds of our country.
The Burrow bird is smaller than the robin , with grey or light brown plumage , black wings and tail with white spots , and a distinct circle of black around the eyes. The European Berau bird is mostly red and brown; the Great Burrow bird in Canada and the United States, also known as the Northern Burrow bird, is the most widely distributed of the Burrow bird; from the Burrow is produced in Africa, there are about 40 species. The body is about 16 to 21 cm long. The plumage is brightly coloured, the beak is not as sharp as other Burrow birds, and the tail has long, soft feathers. The four-colored clump berho is green on the upper body and golden yellow on the lower body. Red throat and black edges, very good looking.
The burrows are incubated by the female, which takes about two weeks to be born, fed by the female and male after birth, and after twelve days the young birds can leave the nest and stand on their own, but they sometimes come back to ask their parents for some food. The Burrow bird also has a strong maternal nature, and when an animal such as a snake tries to attack its nest, the Berlau bird will desperately protect its young birds and fight back.
Because the living environment of the Berau bird is an open grassland and pasture, with the expansion of human cities and the mechanization of pasture farming, the living environment of the Burlau bird is getting smaller and smaller, which has also led to a decrease in the number of Burlau birds year by year, and we can see that the opportunity for this strong, individual bird is also less and less.
The most common species are red-tailed burrow, tiger-striped burrow, brown-backed burrow, grey burrow.
Laniustigrinus is similar to the former , with brownish-red dorsal waist , shoulders , and tail feathers , differing in pure slate grey on the top of the head , a fine wavy black transverse spot on the dorsal waist and shoulder feathers ; and dark brown transverse spots in the tail feathers. The habits are also similar to those of the red-tailed Burrow, which is widely spread in densely wooded areas such as plains, hills and valleys, but is more abundant in mountainous areas. It is also fierce, not only catching insects for food, but also attacking birds and rodents. Most of the food is a pest, such as bumblebees, locusts, pine caterpillars, flies and various insects. It is found throughout the country. Like the red-tailed burrow, this berlaut feeds mainly on insects and most of the time is completely insect-eating. The insects it eats, with the exception of a few beneficial insects, are agricultural and forestry pests; although it also eats some other animals, which are either beneficial or harmful, the number of insects eaten is obviously limited and insignificant, and should be protected.
Gray Burao (l. excubitor) is a common large Burrow in the north of China, the size of the body is similar to the brown-backed Burrow, the whole body is mainly gray-brown, the wings and tail are black, and the outer feathers of the tail are bright white, which is easy to identify. It does not breed in our country, but migrates along the northern provinces of our country in spring and autumn, and a small number of individuals overwinter in our country. Fierce, he is good at preying on rodents, lizards and small birds. In China's Inner Mongolia, northwest and northeast and other regions also often encounter a kind of gray large Burrau that nests and breeds in the local area, although the body color is similar to the gray Burrow, but the body size is larger, especially with significantly long tail feathers, this berau is called wedge-tailed Burrow or long-tailed Grey Burrow (l. sphenocercus）。
The brown-backed laniusschach is the larger of the berau species. The body length is about 240 mm. The main features are grey from the top of the head to the upper back, fading brown backwards; the rest of the upper body is reddish brown; both wings and tail are black, and most of the underparts are white. It is a kind of Burao common in the south of our country. It inhabits open plains and low mountains, and is often found in pastoral areas, orchards and trees. Fierce, with strong beaks and claws, it is good at preying on insects, birds and other animals, and can even kill birds larger than itself, such as partridges. Usually, he often perchs on the reeds, looks east and west, and when he sees food on the ground, he will go straight down to hunt and kill. It can also prey on flying insects and birds in the air. The song is often cocked and vigorous, and can imitate its bird song. Breeds between April and July. The nest is cup-shaped and is made of grass stems, bamboo leaves, young shoots, fern leaves and other debris. Each clutch lays 5 yellow-white eggs with dense, grey-blue and lilac-gray spots of varying thickness and size, and are decorated with rust red or even reddish-brown dots. In the past, it was generally believed that brown-backed Berhoe specialized in feeding on other birds, so it was regarded as a pest bird, and the results of the study proved that it mainly preyed on insects, such as locusts, step insects, black bees, etc., in addition to eating some wild fruits. The slaughtered birds account for a very low proportion of the food they eat, so they are very beneficial to agriculture and forestry. It is found throughout the southern provinces of our country and is a resident bird.
Brown-backed burrows are insectivorous birds that can be fed young with red-spotted chin feed (i.e., mung bean noodles, cornmeal, hard-boiled egg yolk, freshwater fishmeal or silkworm pupae powder mixed in a 5:2; 2:1 ratio), but the growth is not very good, it does not like to sing, and if it is supplemented with fresh defatted beef and mutton, it can improve quickly. In addition, the feed noodles (bean noodles, corn flour) should be as thin as possible, because the coarse slag will be kneaded into a ball in the stomach of Therao and spit out, which has the effect of "scraping oil" and gradually emaciate the birds. Because Berau has no ability to digest cellulose, it is best to have fresh meat in the feed.
Berlau is fierce and sharp in the mouth, and care should be taken when using meat to induce food and daily capture in the early stages to avoid biting. In the early days of breeding on the shelf, the birds are not adapted, always want to escape, easy to hang. Usually, it is raised with a straight frame first, and then switched to a bow frame after the birds are accustomed to living on the rack. The method is to use a thread of about 30 centimeters long to tie it to the neck of the bird, hold the other end in your hand or place it next to guard, and as soon as the bird falls, it will use the neck line to lift it to the straight frame and lure it with fresh meat. Generally 1-2 days, the bird will no longer struggle to escape, but with the neck line as the radius of the flying, each time can accurately land on the straight frame. The neckline can then be shortened, and l/2 birds with a bow frame can also be used to feed with a bow frame when they can also live stably.
If you want to raise the chick island from the nest, you should wait for the young bird down feathers to be replaced by positive feathers, and it is best to leave the nest, so that not only is it convenient to feed, but also the bird grows and develops well. When picking up, you should pay attention to whether there are external parasites, and if there is any, you should get rid of them in time, otherwise the bird will not grow well. The chicks can be fed with boiling water and dough in half of the flour and fresh meat foam, twisted into two pointed grains, 5 to 6 times a day, and the proportion of meat in the evening should be slightly larger, and it should be fed enough. According to the characteristics of Burrow's wild habitat, the bird frame should be hung on a high place indoors. Berau eats more soft food and loose stool, daily management should pay special attention to food and water hygiene. Feed once in the morning and once in the afternoon, that is, after "recognizing" the dry powder, you must also feed a wet ingredient every day, and it is best to add some fresh meat. Live insects and larvae can be held and fed by hand. In addition, Berau is afraid of cold, indoor breeding in winter, room temperature should be above l0 ° C, Berau can also be raised with thrush cages, large breeds with myna cages. But it is not as distinctive as the shelf. Most species of the Berau family are carnivorous birds, and the proportion of fresh meat should be larger than the proportion of meat in the red-tailed berau feed, and even the small birds can often be fed live to be torn apart. Of course, all of Berauco's birds cannot be kept in mixed flocks with other birds.
