Behaviour and reproduction
Wolverines live in the boreal coniferous forest zone. They are largely scavengers, but will also hunt small mammals, and forage for berries and easily digestible plants. Wolverines are not very agile, but in suitable snow conditions they can hunt down reindeer, and like other mustelids they may store their prey, and return later to feed on the same carcass.
Wolverines seem to be in perpetual motion. They are tireless wanderers and skilled climbers. Wolverines mainly move around during the twilight hours, and take care to stay away from human settlements. Males particularly rove over very wide areas.
Reproduction
Wolverines mate in the summer, but foetal development is delayed, and the cubs are not born until the late winter, in a cave, a den among the rocks, or a lair dug into the snow. Cubs typically stay with their mother until the autumn.
