树上狮，赞比西河，赞比亚（摄影：Chris Johns）

赞比亚的赞比西河畔，一头母狮在树上巡视她的领地。每一群狮族里，母狮都是主要的猎手，也是狮族的骄傲。在莽莽草原，它们经常集体出动，捕猎羚羊、斑马、牛羚和其它大型动物。很多猎物都跑得比狮子快，所以集体行动才会有收获。

A female lion claims her spot in a tree near the Zambezi River in Zambia. Female lions are the primary hunters in each family group, or pride. They often work together to prey upon antelopes, zebras, wildebeests, and other large animals of the open grasslands. Many of these animals are faster than lions, so teamwork pays off.
