Newborn baby weasels are born in a nest. The nest is in the burrow. The mother lays in the nest with small pieces of fur from animals she has killed. Baby weasels start to hunt with its mother at the age of two months old. Baby weasels are almost full grown at the age of four.
Weasels are mostly nocturnal.
They hunt at night. In fact, summertime brings almost twenty-four hours of daylight to the weasel in the far north. They can also climb and swim through almost any hole or cranny. Weasels are very good predators. They try to bite their prey in the back of the neck and they can successfully kill prey that is bigger than themselves.
