swallow
Swallows are divided into Swift, Louyan, Domestic Swallow and Swallow. Different swallows have different living habits. For example, swallows and swifts belong to climbing birds, while domestic swallows and golden swallows belong to songbirds. Different kinds of swallows have different shapes. Lou Yan is bigger, flying high, flying fast, black all over, metallic and singing loudly. It likes to nest under the high eaves of pavilions and ancient buildings. Domestic swallows are small, with metallic black hair, chestnut head, white or pale pink abdomen, low flying and low singing. They are mostly on indoor beams and corner nests of residents, and they like to be close to humans. They mainly feed on mosquitoes, flies and other insects. They are well-known beneficial birds, and they have the habit of protecting swallows in the mass era. When the autumn wind is bleak and the leaves are falling, swallows fly to the south in droves, and then fly back to the original place when the willow shoots are in bloom the next spring. Yan will come back at this time every year.
Swift is the fastest bird. It often preys on insects in the air, with long wings and weak legs. Swifts are widely distributed, often breeding in high latitudes and wintering in tropical areas. There are 80 species belonging to 18 genus and 7 species belonging to 4 genera in China.
As early as thousands of years ago, people knew the law of swallows flying from autumn to spring. Ancient poets once described the flying habits of swallows as follows: "In the past, Wang Xietang flew into the homes of ordinary people" and "there was nothing to do with the flowers, as if the swallows had returned." In the autumn before winter, swallows always travel long distances every year-they fly from the north to the far south in droves, where they can enjoy warm sunshine and humid weather, and leave the frost and cold wind of winter to tits, grouse and Thunderbirds who never fly south for winter. On the surface, it is the cold winter in the north that makes swallows leave their hometown for the winter in the south, and then return to their hometown to have children and live and work in peace and contentment in the warm spring season in bloom. Is that really the case? Actually, it is not. It turns out that swallows feed on insects and have always been used to preying on flying insects in the air, but they are not good at searching for insect food in cracks in trees and ground. They can't omnivore berries and seeds like rubber grouse and Thunderbird, and they can't eat leaves in winter (conifers don't lose their leaves even in winter). But in winter in the north, there are no flying insects for swallows to prey on, and swallows can't dig the larvae, pupae and eggs of hidden insects such as woodpeckers and woodfinches. The lack of food makes swallows migrate from north to south every year in order to obtain a broader living space. Swallows have become "nomads" in the bird family.
Domestic swallows have a kind of "strange ringworm": they always move in the dead of night and the bright moon is in the sky, and they fly very fast. Sometimes I can only see my own shadow flash by, but I can't see it clearly. Swallows also have amazing memories. No matter how far you fly, you can return to your hometown with amazing memories even though you are separated by thousands of waters in Qian Shan.
One of the "great events" after the swallow returns to her hometown is that the female bird and the male bird build their own home together, sometimes repairing the old nest and sometimes building a new nest. Domestic swallows bring soil, grass stalks, feathers and so on. Use their mouths and mix their saliva. Not long after, a brand-new bowl-shaped nest appeared under your eaves. Swallows are very light and have a pair of narrow and long wings. When flying, it looks like two sharp sickles. When flying, it is like an arrow just leaving the string, and it is launched with a whoosh. It is an expert in insect catching. It can eat 250,000 insects in a few months. It must not be harmed! Since ancient times, people have been happy to let swallows nest in their own houses and have children, which is considered auspicious and blessed. Although the ground under the bird's nest is often dirty, people don't care. Swallow is a migratory bird with strong seasonality. People call it "Chun Yan coming back in spring" and "Chun Yan coming back suddenly". As long as you see a swallow, it's like reminding people that spring is coming! The ancients once said, "The birds sing and whisper in the New Year" is a quip. People always associate swallows with spring.
Swallows have similar male and female feathers. The top of the head is dark brown, and the sides of the head, the back neck and the side of the neck, and the upper body, including the upper tail feather, winglet feather and inner wing feather, are dark brown.
The wings and tail are dark brown-gray, and the tail feathers are short and slightly concave, almost square. Except for the middle pair and the outermost pair of tail feathers, there is a large white spot at the proximal end of other tail feathers at 1/3.
The chin, throat and upper chest are white, some chin and throat have dark brown or gray spots, the lower chest and abdomen are dark brown sand, and the wings, lower abdomen and lower tail are covered with dark smoke brown. The iris is dark brown, the mouth is black, and the color is flesh and blood.
Young birds are similar to adult birds, but the upper part of young birds is dark, with broad dark brown feathers, and the waist and tail are covered with yellowish feathers. The lower body is reddish brown, and there are no brown markings on the chin and throat.

Golden bird's nest is still the most precious, with its thick nest layer, tender and soft, transparent color and rich nutrition, and is known as the first bird's nest. Swallows are divided into Swift, Louyan, Domestic Swallow and Swallow. Different swallows have different living habits.

They are mostly on indoor beams and corner nests of residents, and they like to be close to human beings. Louyan, White Waist Swift, Family Swallow, Swallow, Grey Shayan and Golden Waist Swallow nest under the mud eaves every spring, and Jin Siyan on the mainland island also begins to spit for the first time. By the late stage of nesting, even the blood was spit out, which felt like "the filariasis in spring will weave until it dies". Therefore, when we collect bird's nest, we often see the situation that the blood in front of the nest turns red. The mother swallow died in the nest because of overwork! Island and Guangdong Huaiji cigarettes are the main producing areas in Jin Siyan. From June 165438+ 10 to March the following year, groups of Jin Siyan flew to the mainland island to nest. There are more than 100 cliff caves on the mainland island, but Jin Siyan only nests in rock caves about 200 meters high in the southeast. The mouth of the cave is narrow at the top and wide at the bottom, so it cannot enter from the top of the rock. Fishermen who collect bird's nest must sail to the lower end of the cave, then dive into the lower water hole and climb up the cave wall. The bird's nest used to be a huge rock, but later the rock split in two, just like an uncanny workmanship. The gap in the middle is about 40 cm wide and cracks from the water surface to the top of the cliff. After entering the cave for more than 2 meters, the cave gradually widened and the light gradually dimmed. The grotesque rocks in the cave are winding, and seawater comes in from the mouth of the cave and other crevices, hitting the stone wall, crashing and thundering. Some stone walls have been eroded and collapsed after years of weathering, blocking the hole and being impenetrable. Occasionally, a narrow beam of light shoots into the cave from the top of the cave and shines on the seam walls on both sides, so that we can get a glimpse of the bird's nest in this weak light.
