Gangly, tawny moose calves are born about nine months after the autumn rut [mating season]. Born at 25-35 pounds, the average adult moose weighs close to 1,000 pounds and stand six feet tall. Calves can walk and swim at one week of age and remain with their mother for 12-18 months. If you’re lucky, you will see a cow with her twins, which are somewhat common.
