Swallows

Swallows are divided into swifts, floor swallows, house swallows, rock swallows, etc. type. Different swallows have different living habits. For example, they are both swallows, the swallows of swifts are climbing birds, and the swallows of barn swallows and golden-rumped swallows are songbirds. Different species of swallows have different shapes. The building swallow is slightly larger, can fly high and fast, is black in color, has a metallic luster, and sings very loudly. It likes to nest under the high eaves of ancient pavilions and pavilions; the house swallow is smaller in size and has a metallic upper body. It is brilliant black, with a chestnut head and a white or light pink belly. It flies low and makes a quiet sound. It mostly nests on the beams and corners of residents' homes. It likes to be close to humans. They mainly feed on insects such as mosquitoes and flies. They are well-known beneficial birds. In the common people, they had the habit of protecting swallows. When the autumn wind is bleak and the leaves are falling, swallows fly in groups to the south. When the spring is warm and the flowers bloom and the willow branches sprout, they fly back to the place where they originally lived. "The swallows return at this time every year."

Swifts are the fastest flying birds and often hunt insects in the air. They have long wings and weak legs. Swifts are widely distributed, often breeding in high latitudes and overwintering in tropical areas. There are 18 genera and 80 species, including 4 genera and 7 species in my country.

As early as thousands of years ago, people knew the migration patterns of swallows in autumn and back in spring. Regarding the flying habits of swallows, ancient poets once described it this way: "In the past, the swallows in front of the king's funeral hall flew into the homes of ordinary people." "The flowers fell helplessly, and the swallows returned as if they had known each other before." Swallows always fly in the autumn before winter comes. Carry out the annual long-distance journey - flying in groups from the north to the far south to enjoy the warm sunshine and humid weather there, leaving the severe winter frost and biting cold wind to those who never fly south for the winter. of chickadees, grouse and ptarmigan. On the surface, it seems that the cold winter in the north causes swallows to leave their hometown and go to the south to spend the winter. When spring comes, they return to their hometown to have children and live and work in peace and contentment. Is that true? Not really. It turns out that swallows feed on insects, and they have always been accustomed to catching flying insects in the air. They are not good at searching for insect food in the gaps between trees and ground, and they cannot eat berries, seeds and food like oak grouse and ptarmigan. Feeds on leaves instead in winter (coniferous species do not lose their leaves even in winter). However, in winter in the north, there are no flying insects for swallows to prey on, and swallows cannot dig out the larvae, pupae and eggs of hidden insects like woodpeckers and woodbirds.

The lack of food forces swallows to make a great north-south migration from autumn to spring every year in order to obtain a wider living space. Swallows have become the "nomads" in the bird family.

The barn swallows have a "strange ringworm": they always fly in the dead of night with the bright moon in the sky, and they fly very fast. Sometimes you can only see their shadows passing by, and you can't see them clearly at all. What it looks like. Barn swallows also have an amazing memory. No matter how far they migrate, even across thousands of mountains and rivers, they can still return to their hometown with the help of their amazing memory.

The first "big thing" after the barn swallow returns to its hometown is that the female and male birds build their own homes together, sometimes repairing the old nest, sometimes building a new nest. Barn swallows constantly pick up soil, grass stems, feathers, etc. in their mouths, and then mix them with their own saliva. Not long after, a brand new bowl-shaped nest appeared under the eaves of your house. The barn swallow is light in body, with a pair of narrow and long wings. When it flies, it looks like two sharp sickles. When it flies, the barn swallow looks like an arrow that has just left the string. It is launched with a "whoosh" sound. It is an expert at catching insects and can grow up in a few months. It can eat 250,000 insects, so we must not harm it! Since ancient times, people have been happy to let swallows build nests in their houses and have children, which is considered auspicious and blessed things. Although the ground under the swallow's nest is often dirty, people don't care. Swallows are very seasonal migratory birds, and people call them "the spring swallows returning in spring", "the spring swallows returning gracefully", etc. Whenever you see swallows, it seems to remind people: Spring is coming! The ancients once had a good saying: "The orioles' crows and swallows' whispers herald the new year." People always associate swallows with spring.

Swallows, male and female have similar feather colors. The top of the head is dark brown, and the sides of the head, the back and sides of the neck, and the upper body, including the upper tail coverts, the small coverts on the wings, and the large coverts on the inner wings are brownish gray.

The wings and tail are dark brown and gray. The tail feathers are short, slightly concave and almost square. Except for the central pair and the outermost pair of tail feathers, which have no white spots, there is a large one in the proximal 1/3 of the inner side of the remaining tail feathers. White spots.

The chin, throat and upper chest are white, and some have dark brown or gray spots on the chin and throat. The lower chest and abdomen are dark brown sand color. The flanks, lower abdomen and undertail coverts are dark smoky brown. The iris is dark brown, the mouth is black, and the tarsometatarsus is flesh-colored.

The young bird is similar to the adult bird, but the upper body of the young bird is darker and has a wide dark brown feather edge, and the waist and tail coverts have light yellow feather edges. The lower body is reddish brown, and there are no brown markings on the chin and throat.

Among them, the golden bird's nest is the most valuable. Its nest layer is thick, tender and soft, transparent in color and rich in nutrients. It is known as the first bird's nest.

It likes to be close to humans. House swallows, white-rumped swifts, barn swallows, rock swallows, gray sand swallows, and golden-rumped swallows. Every spring, barn swallows build nests under mud eaves, and the swiftlets on Dazhou Island also begin to spit for the first time. In the later stages of nest building, Even blood was spit out, and it felt like "the spring silkworm will not run out until it dies". Therefore, when collecting bird's nests, we often see "blood dripping in front of the nest and it turns red". Some mother swallows died in the nest due to overwork! Dazhou Island and Huaiji Yanyan in Guangdong are the main producing areas of swiftlets. Every year from November to March of the following year, groups of swiftlets fly to Dazhou Island to build their nests. There are no less than a hundred cliff caves on Dazhou Island, but the swiftlets only build their nests in a rock cave about 200 meters high on the southeast side. The entrance of the cave is narrow at the top and wide at the bottom, and cannot be entered from the top of the rock. Fishermen collecting bird's nests must drive a boat to the lower end of the cave entrance, then dive into the water hole at the bottom, and then climb up the cave wall. The Bird's Nest Cave was originally a huge rock. Later, the rock split into two halves, as if it was split by a miraculous craftsman. The gap in the middle was about 40 centimeters wide, splitting straight from the water to the cliff peak. More than 2 meters into the cave, the cave becomes wider and the light gradually dims. The strange rocks in the cave are rugged, winding and twisting. Sea water pours in from the entrance of the cave and other stone cracks, hitting the stone walls with a loud roar, a sound like thunder, and splashing droplets. Some stone walls have been weathered over the years and have eroded and collapsed, blocking the caves and making it impossible to penetrate. Occasionally, a narrow beam of light enters the cave from the top and shines on the cracked walls on both sides. Only through this dim light can one see where the bird's nest is.
