Moose

Moose Facts

Growth patterns, age at sexual maturity, and production of offspring are closely tied to range conditions. A female moose, or “cow,” typically breeds at about 28 months, although breeding has been known to occur as early as 16 months. After a gestation period of about 230 days, cows give birth to calves in the spring. At the time of birth, these babies can weigh in at a mere 28 pounds, but within the first 5 months, calves grow to about 10 times that size. Calves are generally weaned in the fall at the time the mother is breeding again, and they are chased off just before she gives birth in the spring.

Adult males engage in the “rut” in late September and early October. During the rut, the males joust by bringing their antlers together and pushing. Serious battles are rare, with most injuries being minor. Occasionally, however, some individuals die from their wounds. The winner typically mates with several females.
