The 2010 article "Smoky Mountain Elk" in AT Journeys magazine says:
Adult male elk weigh an average of 600-700 pounds. Cows average 500 pounds. Adults are seven to ten feet long from nose to tail and stand four-and-a-half to five feet tall at the shoulder. Adult males have antlers that may reach a width of five feet. Their main diet consists of grasses, forbs, acorns, bark, leaves, and buds from shrubs and trees. Cows usually give birth to only one calf per year, and newborns weigh about 35 pounds. They can stand within minutes of birth, and calf and cow usually rejoin the herd within a couple of weeks. Calves nurse for one to seven months. Females are ready to breed in the second autumn of their lives. Coyotes, bobcats, and black bears may kill young, sick or injured elk. Gray wolves and mountain lions, both of which have been extirpated from the Great Smoky Mountains, are also successful predators of elk elsewhere. Elk can live as long as 15 years.
Most elk shed their antlers in March. The antlers, which are rich in calcium, are quickly eaten by rodents and other animals. After they have shed their antlers, elk immediately begin growing new ones. In late spring, elk shed their winter coats and start growing sleek, copper-colored, one-layer summer coats. Most calves are born in early June. Male elk roll in mud wallows to keep cool and avoid insect pests. By August, elk antlers are full grown and have shed their "velvet." Calves have lost their spots by summer's end. Male elk make their legendary bugling calls to challenge other bulls and attract cows. Their calls may be heard a mile or more away. Large bulls use their antlers to intimidate and spar with other males. Most encounters are ritualistic and involve little physical contact; only occasionally do conflicts result in serious injuries to one or more combatants. During the "rut in September and early October, dominant bulls gather and breed with harems of up to 20 cows. Elk wear a two-layer coat during the colder months. Long guard hairs on the top repel water and a soft, wooly under fur keeps them warm. (Elk, AT Journeys)Charles P. ForbesDecember 6, 2010
