- bison took over the great plains...
野牛接手大平原 - ...roaming in huge numbers.
四处游荡 数量庞大 - But they weren't alone.
但它们并不孤单 - With fewer big prey to choose from,
由于大型猎物减少 - bison became the focus of another group of survivors.
野牛成为另一群幸存者的重点目标 - Age-old enemies.
宿敌 - Their best defense is to keep an eye on the danger,
它们最好的防御是警惕危险
