In the wild, nests are mostly built in tree cavities. They can sometimes be found nesting in individual trees, however sparrows are flocks in all four seasons of the year, with old groups of trees with many holes, and are often their favorite nesting spots.

A few small sparrows flew in the yard, and they had russet feathers all over their bodies, as if they were covered with a thick coat. The belly is brown, as if wearing a brown shirt. The head is brown, and it seems to be wrapped around a brown turban.

The claws firmly grasped the fence and chirped incessantly, as if it were in a meeting.

By noon, I saw that they hadn't flown away. I suddenly noticed that its small and delicate mouth moved, as if to say to me, "Child, can you let me stay?" So I brought a cage and put a handful of rice in it, and the little sparrow, seeing that I liked it more, flew into the cage, jumped up and down for a while, and ate the rice.

In the afternoon, I opened the cage and let the little sparrow fly freely in the sky, hiding in the clouds for a while to deliberately not let me see it, and then perching with other birds, and the little sparrow returned to its new home when it was tired of playing. I watched it fly cutely, and I thought how nice it would be if I could fly as freely as a little sparrow! I could fly to Beijing to watch the military parade and see the prime minister waving at me; You can also fly to Hong Kong and visit Disneyland ......

The muscles of the entire hind limbs are distributed in the inner thigh and shin, and the other parts are all muscles, which run through the toes and can control the curvature of the toes, so that the sparrow can grasp the branches and live peacefully. However, there is no articular between the tibial tarsal and the phalanges of the tarsal bones of the hind limbs of the sparrow, so the joints between the tibia and the tarsal bones cannot be bent, which makes the sparrows unable to walk on flat ground with their hind limbs, but can only make rapid and frequent jumping movements.

Sparrow bai generally refers to domestic sparrows, and sparrows are often confused with smaller and more slender sparrows. The sparrow's head is chestnut rather than gray, with two white feathers on its wings and black patches on both cheeks.

Birds are divided into resident birds and migratory birds according to whether they are migratory or not. Sparrows and magpies, which live in the same area in all seasons, are resident birds. Migratory birds migrate along a more fixed route in spring and autumn, between breeding and wintering areas.
