The barn swallow is light in body, with a pair of narrow and long wings. When flying, it looks like two sharp sickles. The arrow that has just left the string is shot out with a "whoosh". It is an expert at catching insects and can eat 250,000 insects in a few months, so we must not hurt it! Since ancient times, people have been happy to let swallows build nests in their houses and have children, and regard it as auspicious and blessed things. Even though the ground under the swallow's nest is often dirty, people don't care. Swallows are People call it a highly seasonal migratory bird, "the spring swallow returning in spring", "the spring swallow returning gracefully", etc. Whenever you see a swallow, it seems to remind people: Spring is coming!

House swallows have a "strange ringworm": they always fly in the dead of night and the bright moon is in the sky, and they fly very fast.

No matter how far they fly, they can still rely on themselves even if they are separated by thousands of mountains and rivers. Amazing memory returns to hometown.

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. Soon, a brand new bowl-shaped nest will appear under the eaves of your house.

Swallows are migratory birds that begin to fly south in autumn and then fly north in spring. The altitude changes of swallows' "flight" can also predict future weather! Swallows feed mainly on catching small flying insects. When the weather turns bad and it rains, the water vapor in the air increases, and the wings of the insects become soft due to the attachment of small water droplets. At this time, the insects cannot fly high. In order to prey on the small insects, swallows, Then they fly low. At the same time, usually when the weather changes from sunny to rainy, the air pressure also decreases, but the pressure of the bottom atmosphere is always higher than that of the upper atmosphere. Perhaps the life of swallows is more adapted to an environment with high air pressure. Through long-term observation, People discovered this rule, and then spread the weather proverb "Swallows flying high will report sunny weather, while swallows flying low will report rain." Swallows are indeed very sensitive, and in some areas people call swallows sacred birds. 2. Write A composition about a swallow

Swallow’s Nest Troubles

I don’t know when there was a swallow’s nest on the eaves of my house.

In the past six years, since my new house was built, no swallows have come to build a nest. No wonder, the exterior walls of new houses are all covered with smooth colored bricks. How can they make a nest?

However, this year a pair of swallows came to my house to make a nest. How could I not be happy? So, I go to see them every morning and evening. However, the tiles were too slippery, and the swallows' nests were not built for a long time. They were stained with mud on several tiles under the eaves. By the end of April, they finally built a nest. Looking at the home they worked so hard to build, I feel happy for them from the bottom of my heart.

After some time, I found that the swallows that used to be in pairs always only had one busy figure, so I asked my grandpa. Grandpa told me: The mother swallow must be hatching the eggs. "YE!" I couldn't help but want to cheer, but I was afraid of disturbing the swallow mother hatching her eggs. The next day at school I told every classmate the good news.

After that, every day after school, I would ask my grandpa, "Have the little swallows hatched?" The morning before yesterday, as soon as I woke up, I went to see them. But the scene in front of me made me dumbfounded: the soil on the ground was mixed with discolored egg yolks, spotted eggshells, scarlet bloodshot... The puppy was licking the egg juice with relish. I almost wanted to cry, but there was nothing I could do. I really hated my new house and the tiles.

I hurried to school, not wanting to see this tragic scene again. Today, I couldn't help but take a look, but what I saw before me was still... Where did they go? Will they dare to come next year?
