Sika deer grow to about 2. Males usually weigh about 90 pounds, while females usually weigh about 70 pounds. Sike deer have a varied diet, which they adapt to their environment. A sika deer’s diet can include marsh grasses, fallen leaves, trees, brushy vegetation, herbs, fungi, myrtle bushes, ground ferns, poison ivy, soybeans and corn. They typically feed at night.
The sika deer has no natural predators in the Chesapeake Bay watershed, but humans will often hunt them for their meat. Its native predators include tigers and wolves. Sika deer primarily use vigilance to protect themselves from predators, often fleeing when threatened. However, their antlers and sharp hooves can also be used in defense. Sika deer Cervus nippon are similar to invasive Axis deer Axis axis in appearance with white spots present on the back through adulthood.
However, sika deer have a black stripe down the back where the spine would be and a white patch on the posterior end surrounded by black hair. The overall body color of sika deer is tan to brown that becomes gray in the winter. Adult male sika deer have antlers with horns pointing forward anteriorly instead of inwards or towards the ears.
Sika deer are aggressive foragers that are known to cause significant damage to vegetation in natural and commercial areas. Farmers often suffer losses of crops and surrounding woodland areas. Sika deer are known to feed most frequently on trees, shrubs, grasses, sedges, holly, conifers, fungi, acorns, bark, heather, and ivy. The ecological niche occupied by sika deer is similar to whitetail deer and red deer allowing for chances to hybridize. Several instances of hybridization between sika deer and red deer have been observed.
Hybridization is detrimental to native deer species that suffer losses in the gene pool leading to reduced species diversity. Unlike native whitetail deer, sika deer are active 24 hours a day with the exception of disturbed areas that are highly populated by humans.
In these habitats sika deer are only active during dark hours of the night. Sika deer are known to live in small to large herds or individually. Herds form and become larger in the fall and winter months creating dense populations.
Breeding season is identified by characterisitc rut behavior exhibited by male sika deer from late August to October. Males will compete with other males for females by selecting a mating territory and defending it by parallel walking, screaming, and eventually fighting. Male-male competitions are very aggressive and can often result in the death of the losing stag.
Sika deer feed on grasses, leaves, twigs, and tender shoots of woody plants, depending on seasonal availability.
In Texas, the spring preference is for grasses, although browse also may be consumed regularly, and browse use increases after the flush of spring growth has passed. The most important food for sika in Texas is live oak, with hackberry, wild plum, mustang grape, Texas sotol, and greenbrier also serving as important browse species.
Favored grasses include Texas wintergrass, fall witchgrass, and meadow dropseed. Forb use generally increases in summer and is lowest in winter. Sika males are territorial and keep harems of females during the rut, which peaks from early September through October but may last well into the winter months. Territory size varies with type of habitat and size of the buck; strong, prime bucks may hold up to 2 ha 5 acres.
Territories are marked with a series of shallow pits, called scrapes, into which the males urinate and from which emanates a strong, musky odor. Fights between rival males are sometimes fierce, long, and may even be fatal. The time of fawning is primarily May through August. After a 7. Zoo longevity records typically range from 15 to 18 years, although an exceptionally long life span of 25 years, 5 months is known for one animal.

This species is small to medium sized with a chestnut brown to reddish-olive coat with numerous white spots occurring in rows on the upper sides. The mid-dorsal area is darker and forms a line from the head to the rump. A white rump patch ringed with a dark stripe is present. The chin, throat, and belly are cream to light gray, and both sexes have a dark neck mane in the winter.
The males have antlers which are narrow and stand erect with points per antler. The rut begins in late September, with the peak of activity in October with calving occurring in May and June. One calf per female is generally produced each year. Sika deer are polygamous with up to 1 male to 12 females.
When alarmed, sika display the large white rump patch and vocalize a series of chirp-like sounds. During the breeding season, males utter a sound similar to a human scream usually at night. In Maryland, the population is expanding at about 0. This is an introduced species from Asia and the only population in Virginia is on Assateague Island. Sika deer are most often seen near marshes at forest edges or in the marsh, however, they are also found in the extensive stands of loblolly pine on the island.
