A deer or true deer is a hoofed ruminant mammal of the family Cervidae. The two main groups of deer are the Cervinae, including muntjac, elk (wapiti), red deer, and fallow deer; and the Capreolinae, including reindeer (caribou), white-tailed deer, roe deer, and moose. Male deer of all species, as well as female reindeer, grow and shed new antlers each year. In this, they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla).
The sika deer, also known as the Northernspotted deer or the Japanese deer, is a species of deer native to much of East Asia and introduced to other parts of the world. Previously found from northern Vietnam in the south to the Russian Far East in the north, it is an uncommon species that has been extirpated in most areas of its native range, except in Japan, where it is overabundant and present in very large numbers.
Eld's deer, also known as the thamin or brow-antlered deer, is an endangered species of deer endemic to South and Southeast Asia.
The red deer is one of the largest deer species. A male red deer is called a stag or hart, and a female is called a hind. The red deer inhabits most of Europe, the Caucasus Mountains region, Anatolia, Iran, and parts of western Asia. It also inhabits the Atlas Mountains of Northern Africa; being the only living species of deer to inhabit Africa. Red deer have been introduced to other areas, including Australia, New Zealand, the United States, Canada, Peru, Uruguay, Chile and Argentina. In many parts of the world, the meat (venison) from red deer is used as a food source.
The Sitka deer or Sitka black-tailed deer is a subspecies of mule deer, similar to the Columbian black-tailed subspecies. Their name originates from Sitka, Alaska, and it is not to be confused with the similarly named sika deer. Weighing in on average between 48 and 90 kg, Sitka deer are characteristically smaller than other subspecies of mule deer. Reddish-brown in the summer, their coats darken to a gray-brown in mid- to late August. They are also good swimmers, and can occasionally be seen crossing deep channels between islands. Their average lifespan is about 10 years, but a few are known to have attained an age of 15.
The sambar is a large deer native to the Indian subcontinent, South China and Southeast Asia that is listed as a vulnerable species on the IUCN Red List since 2008. Populations have declined substantially due to severe hunting, local insurgency, and industrial exploitation of habitat.
Cervus is a genus of deer that primarily are native to Eurasia, although one species occurs in northern Africa and another in North America. In addition to the species presently placed in this genus, it has included a whole range of other species now commonly placed in other genera. Additionally, the species-level taxonomy is in a state of flux.
The elk, or wapiti, is one of the largest species within the deer family, Cervidae, and one of the largest terrestrial mammals in its native range of North America and Central and East Asia. The word "elk" originally referred to the European variety of the moose, Alces alces, but was transferred to Cervus canadensis by North American colonists. The name "wapiti" derives from a Shawnee and Cree word meaning "white rump" for the distinctive light fur in the rear region.
Six species of deer are living wild in Great Britain: Scottish red deer, roe deer, fallow deer, sika deer, Reeves's muntjac, and Chinese water deer. Of those, Scottish red and roe deer are native and have lived in the isles throughout the Holocene. Fallow deer have been reintroduced twice, by the Romans and the Normans, after dying out in the last ice age. The other three are escaped or released alien species.
The Shanxi sika deer is a possibly extinct subspecies of the sika deer. It is also one of its largest, being 105–110 cm tall at the shoulders and weighing 100 kg. The color is tawny or grayish dark, and is brown on the back of the leg. The spots are nearly invisible. It is previously found in two populations in the upland forests of Lüliang Mountains in western Shanxi, while its range might be much larger in historical times, encompassing the entire loess plateau. There has been no sightings of the subspecies for decades and it is now believed to be extinct, though no actual investigations have been done. Although pure bred individuals remain in farms as a breed, there is not enough suitable habitat nor government effort for reintroduction to take place.
The South China sika deer is one of many subspecies of sika deer. Standing 85 cm or 33 in tall at the shoulders, it is a small subspecies that is only a little larger than its Japanese counterpart. The back is brown with a long dark vertebral strip flanked from indistinct white spots, the belly is snowy white. It has previously ranged from Yangtze River Basin all the way east to the coast, going as far south as the border with Vietnam. Today its small population of 300 is widely scattered along its former range, in remote mountains isolated by heavily populated lowlands. About 30 exists in the Tianmu Mountains in northern Zhejiang, 70 to 100 in southern Anhui, and 150 in northern Jiangxi. The population size in southern Guangxi is unknown, and a tiny population might exist in northern Guangdong as well. The population continues to decline due to poaching, and inbreeding is a matter of concern for the quality of its future population.
The Formosan sika deer is a subspecies of sika deer endemic to the island of Taiwan. Formosan sika, like most of the terrestrial fauna and flora of Taiwan, arrived on the island during Pleistocene glacial periods when lower sea levels connected Taiwan to the Asian mainland.
The Sichuan sika deer is one of the many subspecies of sika deer. It was discovered in 1978 and was proven to be a distinct subspecies. It is found in the mountains of northern Sichuan and southern Gansu, which holds the largest population of Sika Deer in China. There are currently 500 individuals left in the wild, and the numbers currently seems to be stable.
The Vietnamese sika deer also known as the indochinese sika deer is one of the many subspecies of the sika deer. It is one of the smaller subspecies, due to the tropical environment they live in. They were previously found in northern Vietnam and possibly southwestern China, but may now be extinct in the wild. There are plans for reintroducing this subspecies in the future.
The Manchurian sika deer or Dybowski's sika deer is a subspecies of deer, the largest of the 14 subspecies of sika deer. It was first described by Robert Swinhoe in 1864.
The Amur leopard is a leopard subspecies native to the Primorye region of southeastern Russia and northern China. It is listed as Critically Endangered on the IUCN Red List, as in 2007, only 19–26 wild leopards were estimated to survive in southeastern Russia and northeastern China.
The Yezo sika deer is a subspecies of sika deer that inhabits the northern Japanese island of Hokkaido. The Hokkaido sika are endemic, although it is not known whether they originated there or migrated from Honshū or areas further south. It is thought that they may have traveled across the Tsugaru Strait between the islands. Genetic study has shown that the separation of the sika population occurred less than half a million years ago. It is possible that northern sika deer may be more closely related to yezo sika deer than to other sika deer. The indigenous Ainu people of Hokkaido have hunted them for centuries and relied on them as a major food source.
The Kerama deer is an endangered subspecies of the Sika deer native to the Kerama Islands.
