The Indian hog deer or Indochinese hog deer (Axis porcinus), is a small cervid native to the region of the Indian subcontinent and Indo-Gangetic Plain. Introduced populations exist and are established in Australia, [2] [3] as well as the United States (in Texas, Hawaii and Florida), and Sri Lanka. [1]
Its name derives from the hog-like manner in which it runs through forests (with its head hung low), to ease ducking under obstacles instead of leaping over them, like most other deer.
Cervus porcinus was the scientific name used by Eberhard August Wilhelm von Zimmermann in 1777 and 1780, based on an earlier description of Indian hog deer brought to England from India. [4] [5] It was placed in the genus Axis by William Jardine in 1835 and by Brian Houghton Hodgson in 1847. [6] [7] In 2004, it was proposed to be placed in the genus Hyelaphus . [8] [9] The proposal has not been accepted, with most authors keeping it under Axis. [10] [1] [11] A subspecies, A. p. annamiticus, was once considered its own species, but is now generally considered the same species as A. porcinus. [1]

A mature hog deer stag stands about 70 centimetres (28 in) at the shoulder, and weighs approximately 50 kilograms (110 lb); hinds are much smaller, standing about 61 centimetres (24 in) and weighing around 30 kilograms (66 lb). They are very solidly built, with a long body and relatively short legs; the line of the back slopes upward from the shoulders to a high rump. The ears are rounded; older animals tend to become light coloured in the face and neck. The Indian hog deer's coat is quite thick, and generally a uniform dark-brown in winter, except for the underparts of the body and legs, which are lighter in colour. During late spring, the change to a summer coat of rich reddish-brown commences, although this may vary between individuals. Many hog deer show a dark dorsal stripe extending from the head down the back of the neck, and along the spine. In summer, there is usually a uniform row of light-coloured spots along either side of the dorsal stripe from the shoulders to the rump. The tail is fairly short and brown, but tipped with white. The underside of the tail is white, and the deer can fan the white hairs out in a distinctive alarm display.
Indian hog deer have preorbital glands on the face just below the eyes and metatarsal glands located high on the side of the rear legs. Pedal glands are located between the cleaves or toes of the hind hooves.
The antlers of a mature hog deer stag are typically three tined, having a brow tine and a solid main beam terminating in inner and outer top tines. However, antlers with more points are not uncommon. [12] The distinctive features of typical hog deer antlers are the acute angle between the brow tine and main beam, and the fact that the inner tops tend to be short and angle back from the main beam and across towards the opposite antler.
The Indian hog deer's status in Pakistan is uncertain; it occurs in northern India, Nepal, southern Bhutan, Bangladesh, Myanmar and China's Yunnan Province, has been reintroduced to Thailand but is locally extinct in Laos and Vietnam. [1] A small, isolated population lives in Cambodia’s Prek Prasab Wildlife Sanctuary. [13]
The Indian hog deer is gregarious only when conditions are favorable and do not form a "unit" at these times, fleeing in different directions rather than in a herd. When alarmed, it makes a whistling vocalization or a warning bark. Home ranges vary widely in size, but average about 0.70 km2 (0.27 sq mi). Males are aggressive, and may become territorial at low population densities, marking its territory with glandular secretions. During the rut, males gather in open meadows, pawing the ground during antagonistic encounters. Harems are not created, with males courting and defending a single female at any given time. Population densities may be as low as 0.1 animals per square kilometer in riverine valleys, rising to over 19 individuals per square kilometer in grassy flood plains.[ citation needed ]
The tiger, leopard and clouded leopard are known predators of the Indian hog deer. [14] Other known predators include the Burmese python and dhole, [15]
Deer or true deer are hoofed ruminant mammals forming 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).
Antlers are extensions of an animal's skull found in members of the Cervidae (deer) family. Antlers are a single structure composed of bone, cartilage, fibrous tissue, skin, nerves, and blood vessels. They are generally found only on males, with the exception of reindeer/caribou. Antlers are shed and regrown each year and function primarily as objects of sexual attraction and as weapons.
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 now uncommon except in Japan, where the species is overabundant.
Eld's deer, also known as the thamin or brow-antlered deer, is an endangered species of deer endemic to South Asia 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 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.
The chital or cheetal, also known as the spotted deer, chital deer and axis deer, is a deer species native to the Indian subcontinent. It was first described and given a binomial name by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach 90 cm (35 in) and females 70 cm (28 in) at the shoulder. While males weigh 70–90 kg (150–200 lb), females weigh around 40–60 kg (88–132 lb). It is sexually dimorphic; males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly 1 m long.
The Southern red muntjac is a deer species native to Southeast Asia. It was formerly known as the Indian muntjac or the common muntjac before the species was taxonomically revised to represent only populations of Sunda and perhaps Malaysia. The other populations being attributed to this species are now attributed to Muntiacus vaginalis. Muntjacs are also referred to as barking deer. It is listed as Least Concern on the IUCN Red List.
Thorold's deer is a threatened species of deer found in grassland, shrubland, and forest at high altitudes in the eastern Tibetan Plateau. It is also known as the white-lipped deer for the white patches around its muzzle.
The barasingha, also known as the swamp deer, is a deer species distributed in the Indian subcontinent. Populations in northern and central India are fragmented, and two isolated populations occur in southwestern Nepal. It has been extirpated in Pakistan and Bangladesh, and its presence is uncertain in Bhutan.
The Kashmir stag, also called hangul, is a subspecies of Central Asian red deer endemic to Kashmir and surrounding areas. It is found in dense riverine forests in the high valleys and mountains of Jammu and Kashmir and northern Himachal Pradesh. In Kashmir, it is found primarily in the Dachigam National Park where it receives protection, and elsewhere it is more at risk. In the 1941s, the population was between 3000 and 5000 individuals, but since then habitat destruction, over-grazing by domestic livestock and poaching have reduced population dramatically. Earlier believed to be a subspecies of red deer, a number of mitochondrial DNA genetic studies later had the hangul as a part of the Asian clade of the elk. The IUCN and American Society of Mammalogists, however, include it in the new grouping of Central Asian red deer, with the Kashmir stag being the type subspecies. According to the census in 2019, there were only 237 hanguls.
The Philippine deer, also known as the Philippine sambar or Philippine brown deer, is a vulnerable deer species endemic to the Philippines. It was first described from introduced populations in the Mariana Islands, hence the specific name.
The Calamian deer, also known as Calamian hog deer, is an endangered species of deer found only in the Calamian Islands of Palawan province in the Philippines. It is one of three species of deer native to the Philippines, the other being the Philippine sambar and the Visayan spotted deer.
The taruca, also known as the Peruvian guemal, north Andean deer, north Andean huemul, northern huemul or northern guemal, is a mid sized deer species that inhabits the high regions of the Andes mountains in South America. The common name taruca means "deer" in both the Quechua and Aymara languages, though these are not interrelated. The taruca is closely related to the southern guemal, the only other member of the Hippocamelus genus.
The Bawean deer, also known as Kuhl's hog deer or Bawean hog deer, is a highly threatened species of deer endemic to the island of Bawean in Indonesia. Due to ongoing habitat loss, small population size and limited range, the Bawean deer is evaluated as critically endangered on the IUCN Red List of Threatened Species. It is listed on Appendix I of CITES. It has few natural enemies except for birds of prey and large snakes such as pythons.
Rucervus is a genus of deer from India, Nepal, Indochina, and the Chinese island of Hainan. The only extant representatives, the barasingha or swamp deer and Eld's deer, are threatened by habitat loss and hunting; another species, Schomburgk’s deer, went extinct in 1938. Deer species found within the genus Rucervus are characterized by a specific antler structure, where the basal ramification is often supplemented with an additional small prong, and the middle tine is never present. The crown tines are inserted on the posterior side of the beam and may be bifurcated or fused into a small palmation.
The Barandabhar forest covers an area of 87.9 km2 and bisects the Chitwan District in east and west Chitwan. Barandabhar, a 29 km long forest patch, is bisected by the Mahendra Highway, resulting in a 56.9 km2 area in the buffer zone of RCNP and 31 km2 is under the district forest office.
Australia has a population of about 25 million, with recent survey estimating between 200,000 and 350,000 recreational hunters in the country. There are around 5.8 million legally owned guns in Australia, ranging from airguns to single-shot, bolt-action, pump-action, lever-action or semi-automatic firearms.
