I don't know when the swallow built a nest like ice cream under my roof. This bird's nest is warm and comfortable, and there is also a family living inside.
There are four lovely swallows living in this swallow nest: father and mother. The swallow's belly is white, like snow falling from the air. Swallows are all black except their bellies, and their eyes are red. The black feathers around just wrapped its red eyes and looked very beautiful. Yan's mother is petite, but Yan's father is strong. Yan's father will always protect this family.
The surface of bird's nest is uneven. When building a nest, swallows peck out wet mud from fields or rivers, and then slowly pile it up, occasionally adding soft things such as hay and feathers. After the nest is built, the mother swallow sits in the nest from time to time and polishes the inner wall of the nest with her abdomen. Finally, it will pad its nest with the hay it has picked up, and the bird's nest will be very comfortable and warm.
Swallows prey at an amazing speed. They spread their wings and spun in the air, and then they caught a bug. Once the swallow catches the food, it is not selfish to feed it to the swallow.
Swallow's body is streamlined, and the plane is modeled after it. People saw that the swallow in black was beautiful, so they made a kind of dress-tuxedo after it. Don't you believe it? Look, the bow tie in front of the tuxedo is the black spot in front of the swallow's neck.
Swallows have sweet voices, are handsome and smart, and can catch pests. What a lovely elf! We should protect them.
