Snakes are cold-blooded animals. In winter they hibernatein holes which are narrow enough only to hold the snakes' bodies. The snakes can sleep through a whole winter without eating and moving. They can not feel any pain. The hibernation period lasts about five months. When spring comes, the snakes come out and begin their normal life.
Snakes can take many things as food, such as mice, sparrows, frogs,birds' eggs, pests and so on. People sometimes can see a snake eat a sparrow. First it moves close to the sparrow, then it puts out its tongue and brings the sparrow into its mouth and swallows it, which makes a lump in the snake's body. After some time the lump disappears.
