Yearling White-tailed Deer
(Odocoileus virginianus)

Yearling bucks (males) separate from the sibling group in September as the rut approaches. Yearling bucks tend to disperse from the mother's home range at this time.
The most common social group in white-tails is an adult doe, her fawns and her yearling female offspring.
Male White-tails are called "bucks" and females are called "does" and young White-tails are called "fawns".


An average adult White-tailed buck weighs between 100 and 150 pounds live weight and stands 32 to 34 inches at the shoulder. Size and weight vary greatly in the White-tailed Deer depending on the the region where it is found. Some whitetail deer from the northern United States and Canada may weigh as much as 350 pounds.

The white-tail was so named because the underside of its tail is covered with white hair and is displayed (Flag) when the deer is running. The belly, throat, areas around the eyes and insides of the ears are white all year long. Hair color is alike in both sexes. The summer coat consists of short, thin hairs that are reddish-brown in color and the the heavy winter coat is longer, grayish brown hairs over a short wooly undercoat.
Sexual Dimorphism: Male are about 20% larger than the female. Males grow and shed a set of antlers each year.

BEHAVIOR White-tail deer are generally considered solitary animals. They are the most nervous and shy of the deer family. The most common sounds heard are whistles or snorts of disturbed White-tails. They are extremely agile and are great runners (up to 30 MPH), swimmers and jumpers. White-tails generally live in a range of only about one square mile, although linear ranges can be much longer. Buck deer do not associate with the females except during the breeding season (the rut), when they actively seek out does for breeding. White-tails communicate with vocalizations and scents. They have an unusual social grouping.
RANGE Scientists have identified 30 subspecies of whitetails in Central and North America. Whitetails occur from southern Canada south through the lower 48 States and Mexico to Panama.
PREDATORS The main predator of adult deer is man. Many are taken as game during hunting season, while thousands more are killed by motor vehicles each year. Sometimes roving wild dog packs (even domesticated dogs in packs) will kill deer. More natural predators are the coyote, bobcat and cougar.
HABITAT White-tailed deer can adapt and survive in a wide variety of terrestrial habitats from the big woods of the northeast to the swamps of Florida. Most woodland deer prefer a habitat of mixed woods, open areas and dense brush thickets to provide food and help conceal them from predators. 
DIET The White-tails are  herbivores. Some foods white-tails may like to eat includes young leaves and stems, grass, berries, bark and nuts. In agriculture areas, they will eat crops such as corn and alfalfa.

Siblings tend to remain together throughout most of the summer.

Yearling does (females) remain in the mother's home range (usually less the a square mile)  and generally rejoin their mother and her new fawns between September and October. Yearling does average about 120 pounds.

Yearling bucks (males) separate from the sibling group in September as the rut approaches. Yearling bucks tend to disperse from the mother's home range at this time. Yearling males home range is much larger than a female and will move many miles. Yearling bucks weigh an average about 135 pounds.
