When do beaver have babies?

Beavers typically have their babies, called kits, in the spring, usually between late April and early June. The gestation period for beavers is about 105 to 107 days, so mating occurs in late winter. A female beaver usually gives birth to a litter of one to six kits, which are born fully furred and able to swim shortly after birth. The kits stay with their parents for about a year before becoming independent.
