How to keep warm in winter

In winter, keep the white waist bird warm, and you need to prepare a breeding nest to let it stay inside, so as to avoid being blown by the wind.This kind of bird's body is not large. I usually like group activities. Only the breeding period will be paired. At other times, dozens or even hundreds of them are together.It is mostly rice, grass, and fruits, and can also eat insects. It is best to pay attention to matching if it is raised manually.
