Wolves live in family groups called 'packs'. A pack usually has a mum, a dad, and their pups from the last few years. They hunt together, look after each other and travel as a group. Pups stay with their parents until they are old enough to help raise the next set of pups.
The famous howl of a wolf is not a scary noise - it is a phone call. Wolves use howls to tell their family where they are, to call them home, or to warn other packs to stay away. Each wolf has its own slightly different voice, so a pack can tell exactly who is howling.
A wolf has an incredible sense of smell, hundreds of times better than ours. They can pick up the smell of a deer from over a kilometre away on a still night. They can also hear very high sounds - much higher than humans can hear.
Wolves try very hard to avoid people. In areas where wolves live, people who work in the forest say they almost never see one. The wolf usually hears or smells them first and slips quietly away. Most Ukrainians have never seen a wild wolf, even though they live in the same country.
