### A close-knit family pack life

Wolves form a thoroughly cooperative society.

- They usually form a family pack of 6–10, made up of an alpha male and female pair and their offspring.
- Living in a pack is far more advantageous for hunting and survival than living alone.
- Within the pack, they share strong bonds, boasting a tight-knit unity.

### Body language spoken through ears and tail

They can express mood and rank without making a sound.

- An alpha wolf shows confidence through an intense gaze and slow, deliberate movements.
- When scared or submissive, it tucks its tail down between its legs.
- Flattening its ears back is also a signal of submission to another wolf.

### A forest chorus that carries 16km away

A wolf's mysterious howl carries a great deal of information.

- A wolf's howl travels across plains and forests, reaching as far as 16km away.
- It lets a pack member out on a distant hunt know its location and guides the way.
- It's also a powerful warning to neighboring wolf packs to stay out of their territory.

### How wolves revived a forest: 'the miracle of Yellowstone'

The restoration of a single animal changed the entire ecosystem.

- When wolves returned to Yellowstone National Park in the U.S. in 1995, the overpopulated herbivores (elk) were brought back into balance.
- As herbivore numbers dropped, aspen saplings that had been on the brink of disappearing surged by as much as 152 times, and the forest grew lush again.
- Thanks to the healthier forest, beavers and various other animals that had vanished returned to the woods once more.
