The white-tailed deer (Odocoileus virginianus), also known as the whitetail, is a medium-sized deer native to both the Nearctic and Neotropical regions.
They inhabit most of southern Canada and all of the mainland United States except portions of the west central states to the California coast. Their range extends throughout Central America to Bolivia.
The lifespan of a white-tailed deer can be from 6 to 14 years in captivity. In the wild, the majority of deer don’t make it to that age because of disease, hunting and automobile collisions. The average life span for wild white-tailed deer is 4.5 years.
White-tailed deer length ranges from 95 to 220 cm (37 to 87 in), including a tail of 10 to 36.5 cm (3.9 to 14.4 in), and the shoulder height is 53 to 120 cm (21 to 47 in). The average summer weight of adult males is 68 kg (150 lb) and is 45.3 kg (100 lb) in adult females.
White-tailed deer have different colors depending on the season and their location. Usually they have greyish fur in winter and reddish-brown fur in summer. They have white patches of fur on their face, throat and lower legs. The tail is brownish-red above and white below.
Males regrow their antlers every year. They begin to grow in the early spring (usually March or April). By late summer a whitetail’s antlers are fully-grown.
A white-tailed deer’s home range is usually less the a square mile. White-tailed deer collect in family groups of a mother and her fawns. When a doe has no fawns, she is usually solitary. Male bucks may live in groups consisting of 3 to 5 individuals, except in mating season, when they are solitary.
White-tailed deer produce several types of vocalizations such as grunts, wheezes, and bleats. These vocalizations, along with other sounds, postures, and scent are used for communication.
White-tailed deer are very nervous and shy; they wave their tails from side to side when they are startled and fleeing.
White-tailed deer have good eyesight and acute hearing, but depend mainly on their sense of smell to detect danger and their ability to run and bound quickly through dense vegetation to escape danger.
They are extremely agile, sprinting up to 48 kilometers (30 miles per) hour and leaping as high as 3 meters (10 feet) and as far as 9 meters (30 feet) in a single bound.
Whitetail deer are crepuscular animals, meaning they are most active during dawn and dusk.
White-tailed deer are herbivores, leisurely grazing on most available plant foods. Their stomachs allow them to digest a varied diet, including leaves, twigs, fruits and nuts, grass, corn, alfalfa, and even lichens and other fungi.
During the mating season, also called the rut, bucks fight over territory by using their antlers in sparring matches.
White-tailed deer mate in late October or early November in the northern parts of their range and in January or February in the southern parts of their range.
Females are pregnant for 6 and 1/2 months and give birth to one to three spotted young, known as fawns. Fawns are able to walk at birth. They are nursed several times a day until they are 8 weeks old, after which they begin to add vegetation to their diet. Fawns are weaned by 10 weeks old.Female fawns may stay with their mother for two years, males usually leave after a year.
Although they were in danger of extinction due to overhunting, they have recently reached their highest numbers.
White-tailed deer are the smallest members of the North American deer family.
Texas is home to the most white-tailed deer of any U.S. state or Canadian province, with an estimated population of over four million.
In the U.S., the species is the state animal of Arkansas, Illinois, Michigan, Mississippi, Nebraska, New Hampshire, Ohio, Pennsylvania, and South Carolina, the wildlife symbol of Wisconsin, and game animal of Oklahoma.
