kestrel, also known as red hawk and tea falcon, is a small bird of prey, with a body length of 31-38cm and a weight of 173-335g. The wings are long, narrow and sharp, and the tail is long, which is very similar in appearance to the yellow-claw falcon. The male bird's head is blue-gray, and the feathers on his back and wings are brick red with triangular black spots. The waist, tail feathers and tail feathers are blue-gray, and the tail feathers also have broad black secondary end spots and white end spots. There is a vertical downward black moustache under the eyes, which is one of the most obvious differences between it and the yellow-clawed falcon. The chin and throat of the lower body are milky white or brownish white, and the rest of the lower body are milky yellow or brownish yellow with dark brown longitudinal stripes and spots, yellow feet and toes and black claws. In addition, the shape of its tail feather is convex, which is different from the round tail of the swallow falcon and the fierce falcon. Kestrel is distributed abroad in Europe, Africa, northeast Asia, Yemen, India, Japan, the Philippines and other places, and is distributed almost all over the country in China. It is the most common falconidae animal, with 11 subspecies in the world and 2 subspecies in China. The named subspecies are resident birds in Xinjiang, resident birds or summer migratory birds in Heilongjiang and northeastern Inner Mongolia, winter migratory birds or tourist birds in Beijing, and rare winter migratory birds in Fujian, Guangdong, Hainan and Taiwan Province. In spring, they moved to the northern breeding grounds from mid-March to mid-April, and moved away from the breeding grounds from the beginning of 11 to the end of 11. Common subspecies are distributed in most areas except Xinjiang, and most of them are resident birds. Kestrel inhabits various habitats such as mountain forests, forest tundra, low hills, grasslands, wilderness, forest plains, farmland and villages, especially in forest margins, glades, sparse forests and wilderness, river valleys and farmland areas with sparse trees, but it is rare in dense forests. Migration often integrates small groups, especially in autumn. Activities begin at dawn every day, and when flying, the wings quickly stir and occasionally glide briefly. When perching, it is mostly on the trees of isolated tall trees in open areas or on telephone poles. The cry is monotonous and sharp, much like the sound of a bell. It mainly feeds on insects such as locusts, grasshoppers, biting insects, crickets, etc., and also eats small-scale spinal propellants such as rodents, passerine birds, frogs, lizards, squirrels and snakes. During the daytime, foraging activities are mainly in the air, or spread their wings in the wind at high altitude, or fly low on the ground to search for food. Sometimes, they incite their wings to stay in the air for a short time to observe their prey. Once they find prey, they fold their wings, suddenly dive down and pounce on it, swallow it on the spot after being captured, and then suddenly fly up from the ground and quickly rise into the sky. Sometimes, we also use the method of standing on the high places of hills and rocks, or standing on the tops of trees and telephone poles to wait until the prey appears in front of us. The breeding period is from May to July. They usually nest in cliffs, rock crevices on hillsides, earth holes, tree holes and old nests of magpies, crows and other birds in trees. The nest is simple and consists of dead branches, which are covered with grass stems, fallen leaves and feathers. Each nest usually lays 4-5 eggs, occasionally as many as 8 eggs and as few as 3 eggs. If the eggs are destroyed, a compensatory nest is usually laid, but the number of eggs laid is obviously reduced, usually 2-3. Eggs are white or ochre in color, densely covered with reddish-brown spots, but some are only covered with a little reddish-brown spots at the blunt end. Usually, 1 eggs are laid every 1 or 2 days. After the first egg is laid, the female bird will not leave the nest, sometimes lying in the nest, and sometimes standing on the protruding rock outside the nest mouth. Hatching eggs is mainly undertaken by females, and males undertake the escort task. They fly back to the stone wall or tree crown near the nest area every once in a while, and occasionally replace females to hatch eggs. The incubation period is 28-31 days. The chicks are late-maturing, weighing only 1.3-1.4 grams when they are hatched. The chicks are covered with sparse white down feathers, with a big head and a thin neck, which are in a crawling state and can barely shake their heads. After 11 days, they turn into light gray down feathers. The chicks are fed by the parent birds and leave the nest for about 31 days. A general term for some species of eagle, bird class and eagle family. Generally, it refers to various birds of the genus Eagle, such as goshawk and sparrow hawk. The male goshawk is about 51 cm long and is divided into five parts: head, neck, trunk, tail and limbs (wings and legs). Except for the black head, the rest of the upper body of the goshawk is mainly pale gray; The lower body is gray, with dark gray horizontal spots and nearly black feather lines. The female bird is similar in feather color to the male bird, but larger in size. The eagle's mouth is curved and sharp, and its claws are sharp and hooked; The wings are big and good at flying, and the temperament is fierce. Daytime activities, mostly inhabiting mountains and plains. Mainly preys on rabbits, wild rats and so on. Migrate to the south in winter. Young birds are domesticated for hunting. Diaodiao is a large bird of prey, with stout body, long and wide wings and tail feathers, and slow fan wings. It often hovers in the high altitude near the mountains, can prey on rabbits, young animals and other large mammals, and is fierce, and likes rabbits, pheasants, quails and even large mammals, such as young musk deer. Nests camp on high mountains and hanging rocks or trees on cliffs, which can often be seen in northeast China during migration. The vulture bird is black and fertile. Shi Kuang said that there are birds in the south, called Qiang vultures, with yellow heads and red eyes, and all five colors are available. -"Shuo Wen" vulture, carving also. -"Guangya" gives birth to a strange material: the wooden arrow pole is feathered. -History of the Huns. Note: "The big carving is also." Several species of large raptors in temperate and tropical regions are related to eagles, eagles and falcons, but their claws are weak and their heads are bald. They mainly or completely feed on carrion, forming the family Aegypiidae and the family Cathartidae, including some of the largest birds. Such as: vulture feathers (old carved feathers. Also known as "vulture") owl, owl: scientific name owl, owl. The common name is bald wren. Living in the jungle or cliff, the night is out and the day is gone, the sound is piercing, people are unlucky, and they are often driven away. Catching rats at night is good for birds. Harrier is a medium-sized bird of prey, and likes to inhabit and breed in near-water swamps. The common species in China are white-tailed harrier, white-headed harrier and magpie. The white-tailed harrier (Aircuscyaneus), also known as the gray eagle, is like a sparrow hawk. The male is gray with white belly and wings. The primary flight feathers of the wing are black, with obvious color difference from other parts, and there are moon-shaped white transverse spots on the waist, which is a remarkable feature of this species. The baby bird is thick brown all over. Female chicks have light lower body color with dark brown fine longitudinal spots. Habitat in open fields and ponds, but also often perched on the ground, flying quickly and lightly, like to fly low to prey on animals in the grass on the ground. Small birds like quail, and sometimes insects and other rodents. Breeding in the northeast and western Xinjiang, when migrating, it is spread all over the country, and it is a tourist bird and a winter migratory bird. The male bird of the white-headed harrier (Circusaeruginosus) has a black upper body, a light lower body, and black-brown longitudinal spots on the head and neck. There is a gray part at the base of the primary flight feather on the back of the wing. When the wings are spread, the black feather at the tip of the primary flight feather is very bright. Female chicks are dark brown with longitudinal spots. The white-headed harrier is bigger than the white-tailed harrier, and there is no crescent-shaped white spot on the waist, so they can be easily distinguished. Living in the low wetland zone of the swamp or the zone with reeds by the water, they are addicted to insects such as grasshoppers, crickets, frogs and birds, and sometimes steal eggs and chicks. Breeding in the northeast and northern Hebei Province, it is a tourist bird in North China and a winter migratory bird in South China. The body of the magpie (Circusmelanolellcos) is smaller than that of the white-tailed harrier. The upper body of male is black or grayish white, and the body color of male chicks changes greatly. The female bird is reddish brown on the top and pale on the bottom, with reddish brown and dark brown longitudinal stripes; The tail is grayish brown with several black belts. It often lives in the near-water grassland and low wetland zone, feeds on insects, lizards, frogs and birds, breeds in Changbai Mountain and other places in northeast China, and can be seen in coastal areas during migration. Kite is an order of birds, falconiformes and eagles. Also known as "eagle", "old kite", "black-eared kite" and "kite", the Latin scientific name is Milvuskorschun. Widely distributed in all parts of China, it is a common resident bird. The kite is 55 ~ 67 cm long. Almost all the surfaces of the upper body and wings are pure dark brown. The feathers from the top of the head to the shoulders are covered with dark brown feathers, and most of the feathers on the wings are decorated with brown and white lines. The tail is forked, which is obviously different from other raptors. The tail feathers are earthy brown with dark brown stripes. Ear feathers are almost pure black-brown, cheeks, chin and throat are grayish white, and there are brown feather dry lines. The rest of the lower body is brown, slightly decorated with brown patterns. Eyes and mouth are dark brown, wax film, feet and toes are yellow, and claws are black. Kites usually inhabit the surface of hills and rocks and trees between valleys, and can be seen in almost all living environments. I like to glide in circles at high altitude, and my eyesight is keen. Once I see the prey on the ground, I will resolutely rush down. It mainly feeds on small animals such as grass rabbits and voles. \ \(kuang) is a large falcon raptor, which usually hovers in the open area, looking down at the prey on the ground, and then swoops down to catch food. There are three common types in China: ordinary, big and hairy feet. Common \(Buteobuteo), commonly known as the earth leopard, looks like an eagle, with a dark brown upper body, a light dark brown lower body, and a short tail, spreading into a fan shape. When flying, the wing is wide, and the tip of the wing is slightly upward. From below, there are dark brown spots on the tip of the primary flight feather under the wing. Often fly in the open farmland, flying slowly, usually catching field rats for food, which is beneficial to agriculture. Breeding in Siberia and Xiaoxing 'anling and Changbai Mountain in northeast China, it begins to migrate in late September every year and moves to southern China, Yunnan and Hainan Island in winter. \(Buteohemilasius is bigger than normal, and its body color is lighter, especially under the body and head. The thigh feathers are brown, which is different from the ordinary white feathers. When flying, the primary flight feathers are black at the apex and white at the base, and the secondary flight feathers are grayish brown. The tail feathers are pale with thin brown stripes. It lives in mountainous areas, is fierce, and likes to eat rodents, rabbits and so on. It breeds in southern Siberia, Chaoyang and Inner Mongolia in northeastern China, and migrates to North China and even the Yangtze River basin in winter. \(Buteolagopus is very ordinary in shape, with dark brown upper body and dark brown tail and wings. Gaskin and his feet are covered with feathers, which is the distinguishing feature of this species. Living in Yuan Ye, cultivated land and other open areas, they often live with the common people and feed on rodents. They are common in the south-central part of Northeast China, western Xinjiang, Shandong, Jiangsu and other places. Finally, because the contents of the questions are too many and too large, it is difficult to say clearly. Often, an animal has multiple subspecies, and it is difficult to find all of them. I hope to understand.
