Deer
Odocoileus hemionus
Small cloven-foot animal. We have both Mule Deer and Black Tail Deer.
Mule Deer: large white rump patch of narrow black-tipped tail, and large ears (about two-thirds length of the head) are very distinctive. Reddish brown coat that changes from tawny brown in summer to dark or grizzled brown in winter. They have a dark brown forehead, a whitish face with a black muzzle, and a white throat patch.
Black Tail Deer are slightly smaller and slightly darker in color, with a small rump patch and a tail that is dark brown or black for most of its length, rather than just at the tip.
During most of the year Black-tailed and Mule deer travel alone or in small groups, but Mule Deer sometimes form larger groups. The social system consists of clans of females that are related to each other by maternal descent and bucks that are not related.
Bucks assert their dominance by taking various threat postures and flailing their front hooves. Also, bucks of unequal size often engage in protracted sparring matches during which they push their antlers together and twist their heads.
They communicate with the aid of scent and pheromones from several glands located on the lower legs. The outside of lower leg produces an alarm scent, the inside of hock serves for recognition and the between the toes leave a scent trail. Deer have excellent sight and smell. Their large ears can move independently of each other and pick up any unusual sounds that may signal danger. Most active at dawn and dusk or moonlit nights.
Cougars are their natural enemy. A full grown deer can run 36 miles per hour and leap obstacles 8’ high.
Food: ranges seasonally in search of food. It is a twig eater, browsing on Douglas fir, salal, blackberries, western red cedar, yew, huckleberries, leafy ferns and grasses and most things we don’t want them to browse on in our yard. A full grown deer can nip off and quickly swallow up to 8 quarts of un-chewed vegetation each feeding and then chews and digests it later. When you see a deer chewing its cud you know it is feeling safe and secure.
Mating or 'rutting' season - November and early December. After the rut, the bucks tend to hide and rest, often nursing wounds. They suffer broken antlers, and have lost weight. They drop their antlers between January and March. Bucks regrow their antlers beginning in April through to August.
Gestation - 6 to 7 months, fawns are born in late May and into June. Twins are the rule, although young does often have only single fawns. Triplets can also occur. Fawns weigh 6 to 8.8 lb. and have no scent for the first week or so. This enables the mother to leave the fawn hidden while she goes off to browse and replenish her body to produce enough milk to feed her fawns. Does are excellent mothers and are very protective of their young.
