I am very unhappy. Swallows eat more than 600 pests a day. The main pests eaten by swallows are mosquito ropes, as well as agricultural pests such as locusts, moths and crickets. According to calculation, a swallow can eat 540 locusts a day.
Swallows eat locusts as well as locusts. They mainly eat mosquito ropes, moths, crickets and so on. Swallows not only have these points, but also spread information to human beings. For example, if it rains, swallows will fly very low.
Wojiayan's pest control ability is equivalent to the effect of spraying pesticides by 20 to 40 farmers. Our swallow is really capable. More than 200,000 bugs are wiped out by our swallows every year.
From April to September, 654.38+080 days, you can eat more than 500,000 to 654.38+ 10,000! What an amazing number! How many pests can a swallow eat? Domestic swallows fly back to China from Nanyang. After the nest is built with mud, the female swallow lays 4-5 eggs, and then hatches for half a month, and the young swallow is born. A pair of swallows can hatch twice a year. At this time, the swallow worked harder. A pair of swallows feed a nest of swallows at least 15 times an hour and 180 times a day, catching an average of 450-500 pests every day, and adding their own food, the total number is more than 600.
A simple calculation can be made: a pair of domestic swallows and their two young swallows can eat 500,000 to 654.38 million insects in 180 days from April to September. What an amazing number! Mosquito rope is the main pest eaten by swallows, as well as agricultural pests such as locusts, moths and mole crickets. It has been calculated that a swallow can eat 540 locusts a day, and the pests eaten by a swallow in summer are connected end to end, which is a whole kilometer long! Someone caught Swift during the incubation period, and there were 370 bugs in its wide and long mouth.
Therefore, in an incubation period, a nest of swift will eat 250 thousand bugs. Swallows kill a lot of insects and make great contributions to agricultural production.
If there are 5,000 corn plants in an acre of corn field, and there is a bug on each corn plant on average, then a pair of house swallows and their chicks can get rid of the bugs in 200-400 acres of corn field. We should protect our swallow, let him fly freely, be very happy and hope other birds.
2. A composition describing swallows in 300 words Spring has come, the grass is green, the flowers are in bloom, and a vibrant and clever swallow comes out to move.

It is small and exquisite, with a short and wide mouth under a pair of bright and flexible eyes.
Swallows are not only beautiful, but also catch pests. They are our good friends.
Although mosquitoes and flies are so smart and fly so fast, they can't escape the sharp eyes of swallows. As soon as the pests appeared, the swallow flew like an arrow, opened its short and wide mouth, and the pests became something in its stomach. Sometimes mother Yan will put pests in her mouth and fly back to the nest to feed her baby!
Swallows are not only experts in catching insects, but also experts in nesting! This reminds me of Bai Juyi's poem' A few early warblers compete for warm trees, who will carve spring mud with new flowers'. Swallows nest under the eaves. They first build them with mud, straw and branches, and then stick them with saliva. It is not easy for swallows to build nests.

In the spring of March, willows spit new buds, peach blossoms bloom red flowers, and lovely swallows fly from the south.
When I was 9 years old, in spring, I saw swallows nesting under my uncle's beams.
I was playing under the window that day. Two little swallows flew to my uncle's house, chirped a few times, and then landed on a tree and looked around. This time, I saw it clearly. It will be two lovely swallows, wearing black coats, showing white shirts on their chests, and their small black eyes are strange and bright. After a long time, they flew away. But after a while, they came back unexpectedly. This time, there is mud in my mouth. I jumped for joy, because I knew the swallows were going to nest under the eaves of my uncle's house.
I saw one swallow pressing the mud ball on the eaves, the other one flew out, and then flew back with mud, and the other one flew out with mud, so the two of them staggered with mud to build a nest. I don't know how long it took, but the swallow finally built the nest into a semicircle, and both ends were tightly connected to the beam. Swallows fly out and come back ... and add a circle to the original semicircle, so that there are more and more circles around the swallow, leaving this "door" on the front, and finally the swallow can only go in by himself. They also brought a lot of straw and feathers to make a good nest. A few days later, it was a great achievement. I saw the swallow get into the nest, stick its head out and cry excitedly. I am also happy for their success.
Bird's nest is not the most beautiful in the world, but it is built bit by bit with small clay balls, which is the crystallization of patience and hard work.
I love the swallow, his lovely appearance and his perseverance.
Little swallow
In the spring of March, willows spit new buds, peach trees bloom red flowers, and smart swallows fly from the south. At that time, I witnessed swallows nesting under the beams of my uncle's house. I was playing in the yard when suddenly two swallows flew to the front of the house, circled in front of the house, chirped, and then landed on a tree in front of the door and looked around. They seem to say, this place is really nice, let's build a nest here! I can see clearly that they are a man and a woman, a couple. Two lovely swallows, wearing gray coats and revealing white shirts on their chests, have strange and bright small black eyes. After a while, they flew away, and I felt a little sorry. But I still wait patiently, hoping that they will come again. After a while, two swallows did fly back, this time with mud in their mouths. I was overjoyed, because I knew the swallow was going to settle down in the corner of my uncle's house. I saw swallows sticking mud in the corner, one flew out and the other was still sticking. After a while, that one flew back with mud in its mouth, and this one went out with mud in its mouth, so they took the mud to build a nest in a cycle. I don't know how long it took, but the swallow finally built the nest into a semicircle, and the two ends of the semicircle were tightly connected to the corner. The swallow flew out again and came back to add a circle to the semicircle. One day, two days ... there are more and more swallows' circles, and the nests are getting bigger and bigger, which is almost over. There is a "door" on the front, and only swallows can be accommodated in the end. They brought many leaves and feathers to build their nests. You're finished. I saw those little swallows get into their nests, stick their heads out and cry excitedly. I am also happy for their success.
Although bird's nest is not the most beautiful masterpiece in the world, it is built bit by bit with a small mouth, and it is the crystallization of sweat, hard work, wisdom and perseverance. Ah, Swallow, you are a great architectural expert in the world.
I love the swallow, love its lovely appearance, and admire its perseverance and spirit of not giving up until it reaches its goal!

My home is in a small mountain village, with brand-new air and good environment.
Every morning, you can see many swallows parked on the wire in front of your house. One Sunday morning, I was playing at the door.
Suddenly, I found an injured swallow falling, so I ran to pick it up. "What a pity! Where is your mother? Let me take you home first! " So I ran home with it. When I got home, I took out the medicine box from the cupboard and wrapped the gauze tape inside it around the swallow's injured foot.
Time passed slowly, and the swallow recovered day by day under my care. The swallow finally recovered, and my anxiety calmed down.
It's time for the swallow to return to its real home. Early in the morning, I reluctantly put the swallow back into the embrace of nature, hoping that it wouldn't be hurt again and went to find its mother.
