What did the swallow do?

Second, north-south migration. Birds will migrate back and forth in spring and autumn, such as geese, swallows, red-crowned cranes, swans and so on.

This kind of bird is called migratory bird. However, some wild animals or insects will migrate, such as Tibetan antelopes and American monarch butterflies in Hoh Xil, Tibet, China.

Third, hibernate. When the temperature drops, the body temperature of hibernating animals is just kept at the level to avoid freezing to death. When hibernating, they can go without eating or drinking for several months and will not starve to death.
