What's wrong with the sparrows do not reproduce
Park artificial breeding is difficult, let alone breeding. There is no suitable environment, and it is normal for birds to not reproduce.This bird is widely distributed in my country, and the reproduction of different regions is different.The breeding period in the northern region is short, while the south is much longer, so the number of reproduction is different.It can reproduce at any time outside of winter, and can produce 6 eggs each time, which can be incubated after 14 days.
