中英文本
We are here in Yellowstone National Park to follow some grey wolves and observe the deadly brilliance of the pack. They've learned to cooperate, hunting their prey with many acting as one pack. This mother grizzly knows how to protect its cub and itself. Stand your ground. Don't be intimidated. Don't let the grey wolves run you down.
现在我们正在黄石国家公园，跟拍一些苍狼，一睹这些致命尤物的风采。苍狼很懂如何合作，可以团结如一地捕捉猎物。这位熊妈妈知道如何保护自己和自己的孩子——坚守阵地。别怂，别让苍狼把你扑倒。
Grizzly mum stands up to the grey wolves. And eventually, they lose interest. Stand up, hold your ground. Wolves know that large prey can be dangerous if they fight back. What the wolves want is to get their prey on the run. Like, for example this herd of elk. Now the wolves can fan out over the herd, waiting for an old or sick or just unlucky elk to make a wrong move. The alpha male leads the hunt. He bides his time, directing his troops. And eventually, one elk stumbles.
熊妈妈站定在苍狼群面前。最后，苍狼失去了兴趣。站定并坚守阵地。苍狼知道如果他们进攻，大熊会很危险。苍狼的目标是让自己的猎物四处桃村，眼前的这个麋鹿群就是个例子。现在，苍狼可以呈扇形包围麋鹿群，然后只需要等待某只年事已高、病弱无力或者一时不走运的麋鹿走位失误了。苍狼首领指挥着这次的围捕。他在等待时机，并指挥自己的团队。最后，终于有一只麋鹿踉跄栽倒。
The hungry wolves quickly surround their faltering victim. They swarm in for the kill, and then, the meal. Wolves are a vital part of a healthy Yellowstone echo-system. They filter out sick and weak animals in the herds and help scavengers survive but providing leftovers from their hunts. This coyote however is not a scavenger but also a competitor, who's been interfering with the kills of the pack. So once again, the wolves use cooperation to guard their turf and drive out the intruder.
饥饿的苍狼迅速将这只步履蹒跚的猎物重重围住。他们蜂拥而上，要将这只麋鹿杀死，再开动大餐。苍狼是黄石公园生态系统得以健康发展的关键部分。他们过滤掉了病弱的动物，让食腐动物得以存活，将自己吃下的猎物留给了食腐动物。这只郊狼不是食腐动物，而是竞争对手，因为它一直在干预苍狼团队的捕猎进程。所以，苍狼队再次通过合作守住了自己的地盘，驱赶走了入侵者。
