01. Whenever I pass by the corridor, I want to see the swallows making their nests.

Swallows have a hard time building nests. They have to go far away every day to pick up mud. They chew the mud in their mouths and then stick it to the eaves.

I thought, this swallow is building its nest bit by bit, when will it be completed? 02. In the spring, there was a swallow's nest under the eaves of my grandma's house. There were three swallows living on it, a mother swallow and a father swallow.

One is a newly born baby swallow.

03. They are very skilled in making nests, and they finished it in less than a while. They pecked at the mud in the yard, put the mud on the trees, and then surrounded it with hay. After a while, their "house" was built.

It's done.

04. The young couple holds grass stalks in their mouths and mud balls in their mouths, and work together to build a small nest.

They chase moths, catch caterpillars, and share food with swallows with yellow fur and mouth.

The swallow's nest is never fortified, and it spends its days and months with its owner, sipping, squeaking, chatting and laughing, and is very happy.

05. My little swallows fly in and out from under the eaves every day, chirping and playing in the air. Even on rainy days, they go out to look for food.

In November last year, the weather gradually got colder, and the little swallows flew quietly to the south to spend the winter. I have been thinking about them in my heart. Can they fly such a long distance? Can they really fly back next year? 06.

Swallows are clever architects. They build their nests on the lamp bases on the wall, which is labor-saving and strong.

Swallows are also very hygienic. They decorate the "house" every year when they come. They put new bedding in the nest and raise the walls. 07. There is a bird in my house, wearing a noble and elegant tuxedo.

The small and cute mouth, coupled with the handsome and brisk wings, looks dark and graceful. Needless to say, no need to guess, this is a lively and clever little swallow. 08. The swallow's flight gives people a light and graceful feeling.

I feel that the arrival of the swallows brings a sense of auspiciousness and tranquility. 09. In the spring, the swallows made a nest under the eaves of my house. Later, the old swallows hatched and the little ones always flapped their wings.

, murmuring with her yellow mouth open, how fun it is! 10. In the spring garden, the tender green soft willow grew long hair, and as the wind sang, she followed

Dancing gracefully. The green peach leaves were dotted with pink peach blossoms. Yingying looked at the endless scenery and saw her new and old friends? Lively and cute little swallows flying back from a distance.

Then you know that spring is here. Little swallows, dressed in floral clothes, come here every spring and sing songs while watching the little swallows building their nests in her house. Unexpectedly, a young swallow bumps into her.

, fell from the tall house. Upon seeing this, Yingying immediately rushed from the study to the place where the swallow fell. 11. The swallow has a streamlined body, and the airplane is modeled after it.

The black dress is so beautiful that it is also made into a tuxedo. Don’t you believe it? Look, the bow tie on the front of the tuxedo is the black spot on the front of the swallow’s neck. 12. It was a sunny day.

In the morning, I heard a strange sound. I walked over quietly and took a look. It turned out that the swallow mother had given birth to a little swallow. When the swallow father and mother went out to look for food, I stood on the stool and carefully

The little swallow took it down and looked at it carefully. Its eyes were closed and its body was as wet as if it had just been taken a bath. After a while, the swallow's father and mother came back, and I immediately put the little swallow in the nest.

The little swallow opened its mouth, and the mother swallow put the caught bugs into the little swallow's mouth little by little. In this way, the little swallow grew up day by day, and soon it learned to fly towards the warm south.

Fly away, because autumn has arrived. 13. After about nine or ten days, the overlapping bird's nests the size of porcelain bowls finally appeared under the eaves. Looking at the bird's nests, I was stunned and finally understood, swallows.

The ability to build such a beautiful and strong nest is the result of hard work and hard work. 14. Swallows are always very particular about making nests, using soil, branches, grass stems, feathers and saliva.

, built the nest into a half-bowl shape, which is very strong. I think they also know how to build! 15. Swallows have black clothes, white bellies, scissor-like tails, pointed mouths, and small eyes. They are particularly special.

Cute! I learned from extracurricular books that swallows can herald spring and eat pests, and are good friends of crops. 16. Swallows are a genus of the order Passeriforme. In ancient times, people called them birds.

There are more than 20 kinds of swallows in the world, such as floor swallows, white-rumped swifts, barn swallows, and rock swallows.

17. When I opened my eyes, there was only one swallow lying down on the road.

The swallows that were originally chirping now drooped their heads, contracted their wings and remained motionless on the road, and their shining eyes had lost their luster.

I knew that this poor little guy would die soon, and I felt very sad.

But this swallow still struggled and screamed hard, as if it was asking for help from his relatives, as if it was making the last struggle of life, and as if it was making a plaintive rebuke to the humans who destroyed his life.

In any case, his voice was getting lower and lower.
