the Bird Banding Centre of China
Do you remember the song "little swallow (燕子),wears bright clothes,and comes here every spring"?Have you ever wondered where all the swallows go during winter?They fly south in autumn to stay warm and fly back north next spring.This type of travel is called migration (迁徙).
Not all birds migrate.Some who don't need to worry about food live in the same place all year round.Robins (知更鸟),for example,can turn to fruit if they can't find worms or insects.
For birds like swallows,who can't find much food,winter is a hard time.Plants die and insects hide.The swallows have to move to warmer places.
There are over 1,300 kinds of birds in China.More than half of them,about 700 kinds,migrate,says Hou Yunqiu,an expert at the Bird Banding Centre of China.This includes swallows,wild ducks,swans and wild geese.
To study migration,scientists band many birds every year.Some are caught again,or found after they die.By checking the band number with the Bird Banding Centre,scientists learn where the bird was first banded and how far it travelled.
"China started banding birds only about 20 years ago," said Hou Yunqiu."There's still a lot to be discovered."
