Reeves's muntjac (Muntiacus reevesi), also known as the Chinese muntjac, [2] is a species of muntjac found widely in south-eastern China (from Gansu to Yunnan) and Taiwan. [3] It has also been introduced in the United Kingdom, Ireland, the Netherlands, Belgium, and Japan. It takes its name from John Reeves, [4] a naturalist employed by the British East India Company in the 19th century.
Reeves's muntjac grows to 0.5 m (1 ft 8 in) high at the shoulder [5] and 0.95 m (3 ft 1 in) in length, plus a short tail up to 4 in (10 cm) long. It weighs between 10 and 18 kg (22 and 40 lb) when fully grown. It is reddish-brown in appearance with striped markings on its face. [5] The belly is creamy-white, with lighter fur extending to the neck, chin, and the underside of the tail. The males have short antlers, [5] usually 4 in (10 cm) or less, and long upper canines (tusks), usually about 2 in (5.1 cm) long. Females have bony lumps on their foreheads and localized black spots. The Taiwanese subspecies (M. r. micrurus), commonly known as the Formosan Reeves's muntjac, is darker than other subspecies.
Reeves's muntjac feeds on herbs, blossoms, succulent shoots, fungi, berries, grasses, and nuts, and has also been reported to eat tree bark. Eggs and carrion are eaten opportunistically. [6] It is also called the barking deer due to its distinctive barking sound, [7] though this name is also used for other species of muntjacs. The barking sound is common during mating or when provoked. Its preferred habitats are forest and shrubland. It is a solitary and crepuscular animal. Both males and females defend small territories that they mark with preorbital gland secretions that are thought to be pheromonal in nature. [8] When fighting, males first use their antlers to push enemies off balance so they can wound them with their 2 in (5.1 cm) upper canine teeth.
Female muntjacs (known as "does" [7] ) become sexually mature within the first year of life. [9] Mating occurs throughout the year. Their gestation period lasts from 209 to 220 days. [10] Females limit the number of mating bouts, though time between successive bouts is determined by males [11] (known as "bucks" [7] ).
It is widely found in south-eastern China (from Gansu to Yunnan) and Taiwan. [3] It has also been introduced in several other regions.
It has been introduced in Belgium and seen in the Netherlands. [12]
In Europe, this species is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). [13] This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union. [14]
Reeves's muntjacs were first introduced to the UK in the early 19th century. [15]
In the late 19th century, the then Duke of Bedford brought some to Woburn Abbey in Bedfordshire, then in 1901 released them into the surrounding woods. [15] : 96 A few more probably escaped from the nearby Whipsnade Zoo. During the mid-20th century, Woburn conducted several deliberate releases in distant locations throughout England. [15] : 97 It is suspected that there were also other unrecorded releases or escapes from private collections. These releases later caused misperception that muntjacs spread very rapidly. [15] : 98 The estimated population of Reeves's muntjacs in England was 52,000 in 1995, [2] and 104,000 in 2008. [15] : 100
Under the Wildlife and Countryside Act 1981 it was illegal to release the species except where already established, and the Invasive Alien Species (Enforcement and Permitting) Order 2019 has subsequently prohibited the capture and re-release of muntjac in all cases. [16] As of 2017 [update] , colonies exist throughout England south of the Humber, and the population continues to grow. [17]
It has been introduced in the Republic of Ireland. [18]
Sightings in 2008 caused the government, concerned at the risk of the species becoming established, to quickly introduce a year-round hunting season. [19]
Sometime before the 1980s, several specimens escaped from an exhibition zoo in Chiba Prefecture in eastern Japan. [20] By 2023, their numbers had grown to 71,500. [20] It is considered a harmful invasive species. [21] Also, Reeves's muntjac escaped a zoo on Izu Ōshima in 1970 when a fence fell due to a typhoon. They have inflicted severe damage to the local ashitaba plantations. [22] A muntjac eradication effort on Izu Ōshima was undertaken in 2007–2014 but failed, and as of 2014, at least 11,000 individuals exist and have a yearly population growth rate of 15%. This failure has been blamed on inadequate survey methods. [22]
In Hong Kong, Reeve's muntjac is a protected species under the Wild Animals Protection Ordinance Cap 170. It is listed as least concern by the IUCN due to being generally common and widespread. [1]
The tanned skin of Reeves's muntjac is notable for its softness and is occasionally used in beauty-care products, musical instruments, lenses, and antique items packaging. Low-fat muntjac meat is also noted for its culinary qualities. [23]
A deer or true deer is a hoofed ruminant ungulate of the family Cervidae. Cervidae is divided into subfamilies Cervinae and Capreolinae. Male deer of almost all species, as well as female reindeer, grow and shed new antlers each year. These antlers are bony extensions of the skull and are often used for combat between males.
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.
Muntjacs, also known as the barking deer or rib-faced deer, are small deer of the genus Muntiacus native to South Asia and Southeast Asia. Muntjacs are thought to have begun appearing 15–35 million years ago, with remains found in Miocene deposits in France, Germany and Poland. Most are listed as least-concern species or Data Deficient by the International Union for Conservation of Nature (IUCN), although others such as the black muntjac, Bornean yellow muntjac, and giant muntjac are vulnerable, near threatened, and critically endangered, respectively.
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 leaf muntjac, leaf deer or Putao muntjac is a small species of muntjac. It was documented in 1997 by biologist Alan Rabinowitz during his field study in the isolated Nogmung Township in Myanmar. Rabinowitz discovered the species by examining the small carcass of a deer that he initially believed was the juvenile of another species; however, it proved to be the carcass of an adult female. He managed to obtain specimens, from which DNA analysis revealed a new cervid species. Local hunters knew of the species and called it the leaf deer because its body could be completely wrapped by a single large leaf. It is found in Myanmar and India.
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.
The water deer is a small deer species native to Korea and China. Its prominent tusks, similar to those of musk deer, have led to both subspecies being colloquially named vampire deer in English-speaking areas to which they have been imported. It was first described to the Western world by Robert Swinhoe in 1870.
The tufted deer is a small species of deer characterized by a prominent tuft of black hair on its forehead and fang-like canines for the males. It is a close relative of the muntjac, living somewhat further north over a wide area of central China and northeastern Myanmar. Suffering from overhunting and habitat loss, this deer is considered near-threatened. It is the only member of the genus Elaphodus.
The Gongshan muntjac is a species of muntjac living in the Gongshan mountains in northwestern Yunnan, southeast Tibet, Northeast India and northern Myanmar.
The Bornean yellow muntjac is a muntjac deer species, endemic to the moist forests of the island of Borneo.
The Javan rusa or Sunda sambar is a large deer species native to Indonesia and East Timor. Introduced populations exist in a wide variety of locations in the Southern Hemisphere.
Thorold's deer is a threatened species of deer found in the grassland, shrubland, and forest habitats, at high altitudes, of the eastern Tibetan Plateau, as well as some fragmented areas further north in central Western China. It is also known as the white-lipped deer for the white fur around its snout.
The Cervinae or the Old World deer, are a subfamily of deer. Alternatively, they are known as the plesiometacarpal deer, due to having lost the parts of the second and fifth metacarpal bones closest to the foot, distinct from the telemetacarpal deer of the Capreolinae.
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 preorbital gland is a paired exocrine gland found in many species of artiodactyls, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye. They are lined by a combination of sebaceous and sudoriferous glands, and they produce secretions which contain pheromones and other semiochemical compounds. Ungulates frequently deposit these secretions on twigs and grass as a means of communication with other animals.
Clapgate Pits is a disused quarry near Broughton, Lincolnshire. This 1.0 ha site has been managed by Lincolnshire Wildlife Trust since 1996. It provides an environment for several plants which are rare in Lincolnshire: pale St John's-Wort, Squinancywort and Wall Germander. Until 1969 it was the most northerly site in Britain for Pasqueflower but these plants were apparently dug up by vandals.
