Elk are members of the deer family which comprises ( from largest to smallest ) moose, elk, caribou and deer. The bulls weigh from six hundred to eight hundred pounds or more. Elk have eyes on the sides of their head which lets them see in about any direction except behind them. Elk are large ungulates found in Europe, North America, New Zealand, and the Far East. They are highly flexible, prospering in a large range of environments. Elk now live as far east as Pennsylvania, where they were reintroduced in the early 1900s, and now more than seven hundred elk wander thru forests in the north-central part of the state. Elk populations are also growing in other states where they had virtually vanished.
Elk can be pale grey, tan, or brownish to reddish in color, depending on the species. Bulls have a tendency to be lighter colored than cows. The pale rumped American elk called "wapiti", which is Shawnee for "white rump", are found in the woods, mountain meadows, foothills, plains, swamps, and coniferous forests of western North America. Elk are powerful and muscular. Bulls are some twenty five percent bigger than cows at maturity. Elk are one of the largest land animals in North America, and are the most common larger mammal found in Yellowstone National Park. They are herbivorous animals who can find lots of food in places where deer typically can't. They consume an average of 20 pounds of food every day. Elk are ruminant animals, similar to cows, and therefore regurgitate their food and remasticate to help in digestion.
Elk grow antlers that provide a method of defense, as does a powerful front-leg kick, which is performed by either sex if incited. Antlers are made from bone which can grow up to one inch each day. Antlers that are in the growing stage are soft and workable and covered with hairy skin, which is called velvet. Elk shed their antlers starting in late February for the largest males, extending to late April and even early May for the younger ones. Every year they start growing new antlers again in summer. These antlers can weight up to 40 pounds and be up to 5 feet wide.
Elk also lose and replace their hair twice yearly, once in the spring and again in the autumn. They often roll in mud wallows to loosen their dead winter coats and help dislodge annoying parasites. Elk are best viewed at a distance, using binoculars or a spotting scope for close-up viewing.
Elk are primarily crepuscular, most active early in the morning and late in the afternoon. They are timber-oriented animals, preferring to be in the cool shade. Elk are social creatures. They live in summer herds with as many as four hundred others. Elk can live twenty years or longer in captivity, but average 10 to 14 years in natural habitats. Bulls often don't live as long as cows, seldom exceeding twelve years.
