Today's useless fact - Do deer antlers fall completely off each season and then grow back the next spring?

Yes, deer antlers fall off every year. This generally happens in the springtime and the antlers begin to grow back almost immediately. The only variation comes from the age of the deer. In North America, younger deer sometimes keep their antlers until May; older deer begin shedding in February and March. Growth and hardening of the antlers is completed in late July or August, and the reduced daylight of winter diminishes testosterone production, which causes the shedding of antlers. Deer antlers can grow an astonishing .39 inches per day. Elk antlers can grow more than 1.05 inches per day! Check out the links in our Antlers category and Deer category for more.
