We are here in Yellowstone National Park to follow some grey wolves and observe the deadly brilliance 1 of the pack. They’ve learned to cooperate, hunting their prey 2 with many acting 3 as one pack.
This mother grizzly 4 knows how to protect its cub 5 and itself. Stand your ground. Don’t be intimidated 6. Don’t let the grey wolves run you down. 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 7 of elk 8. 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 9 his time, directing his troops. And eventually, one elk stumbles.
The hungry wolves quickly surround their faltering 10 victim. They swarm 11 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 12 and help scavengers survive but providing leftovers 14 from their hunts. This coyote however is not a scavenger 13 but also a competitor, who's been interfering 15 with the kills of the pack.
So once again, the wolves use cooperation to guard their turf and drive out the intruder.
