Deer

deer
Deer are the ruminant mammals forming the family Cervidae . A number of broadly similar animals from related families within the order Artiodactyla (even-toed ungulates) are often also called deer. Male deer of all species (except the Chinese water deer) grow and shed new antlers each year – in this they differ from permanently horned animals such as antelope – these are in the same order as deer and may bear a superficial resemblance. The Musk deer of Asia and Water Chevrotain (or Mouse Deer) of tropical African and Asian forests are not true deer and form their own families, Moschidae and Tragulidae, respectively. All other animals in Africa resembling deer are antelope.
Deer usually inhabit a relatively small home range, until harsh weather conditions force them to temporarily move elsewhere. Thus, deer in northern states have larger home ranges, since the winters are often long and brutal. Some northern deer travel 50 miles or more to suitable winter ranger. Weather is not the only factor that impacts on a herd's home range. For example, most whitetails in Colorado or Kansas have larger home ranges than deer in Virginia or Alabama. Out West, the habitat is more sprawling and open and the doe densities are not as high as in the Southeastern states. Thus, western deer are forced to move longer distances to feed, bed and breed.

The lifespan of a whitetail is 11 to 12 years (17 to 20 years in captivity). But most free-roaming deer never live that long; they are hit by cars, succumb to disease, killed by predators or shot by hunters. In heavily hunted areas, many bucks live only 1½ or 2 ½ years. Deer grow to about 6 feet long and stand 3 to 4 feet high. They are reddish or grayish in color, depending on their habitat and the time of year. The weight of whitetails varies, from 100 to more than 300 pounds.
