Every year from July to October, lots and lots of wild animals change homes in Africa. They make their way from south to north. They are looking for two things - food and water. The animals travel about 3, 000 km. That's about the same way from Beijing to Sanya in Hainan.

Zebras, wildebeests(角马)and gazelles(瞪羚)make a great team.
