Tail bushy and straight, not curled like most dogs. Has tremendous stamina, often spending eight to 10 hours a day on the move. Territory usually ranges from 42 to 100 square miles around the upper Great Lakes. Can hear each other's howls 4 to 6 miles away. Mates in February, digs den in March, gives birth in mid- to late April.
Litters usually number four to six pups.
Primary food source is white-tailed deer. Also eats beaver and other small mammals. Now the wolf is making what biologists consider a remarkably strong recovery, thanks to migration and strict protection laws. They were almost hunted and hounded out of existence, and now they've come back of their own accord. And people are allowing them to survive.
