Habitat: Urban & gardens, deciduous woodland

Description: A small, hump-backed deer (a bit larger than a fox), with a small tail and not as much of a white “target” as with sika or fallow deer. Ginger pelage with dark stripes on the face. Males have short slightly hooked antlers born on long pedicels, sloping strongly backwards, and long protruding canines.

Size: 77-91 cm; tail length 13-18 cm; shoulder height 45-52 cm.

Weight: Males 12-17 kg; females 10-16 kg

Lifespan: Up to 16 years for males in captivity and female >20 years. Wild males 10 years and 13 years for a female.

Origin & Distribution: Reeves’ muntjac are native to SE China, including Taiwan and Hainan. Introduced to Woburn Park, Bedfordshire, in 1894, they were deliberately released into surrounding woodlands from 1901 onward. Releases, translocations and escapes from the 1930s onwards resulted in wide establishment in SE England, and they are still spreading. They are susceptible to severe winters, but their small size and preference for thick cover enables them to adapt to suburban habitats. In some parts of SE England, they are very abundant, reaching 100/km² in prime habitat. Muntjac prefer deciduous woodland with a good understorey. Hedgerows, gardens, conifer plantations and railway embankments are also used, and in woods of conservation interest, they can do serious damage to important wild flowers (bluebells, primroses, oxslips, honeysuckle, orchids).

Diet: They feed on shoots of shrubs, woodland herbs and garden plants, but bramble and raspberry are their most important foods.

General Ecology: Bucks are territorial, marking prominent tree trunks and boughs with scent from glands on their forehead. Their territories overlap the home ranges of several does. Does are slightly more tolerant of each other, but maintain an exclusive core area. Muntjac do not form herds, but are seen either solitary or in family groups of a doe with her fawn. Oddly for a deer in Britain, but reflecting their subtropical homelands, muntjac breed all year round.

Breeding: The female has just one fawn (rarely twins), after a gestation of 210 days. Fawns are born throughout the year, and the doe has an immediate oestrus. She can therefore be almost continuously pregnant, and produces around 3 fawns every 2 years. The young bucks start to develop antlers at around 25 weeks, whatever the month, and shed the velvet at 46-76 weeks. The first antlers are shed in late May (when the young buck may be anything from 52-112 weeks old) but then regularly each year at that time.

Conservation Status: Reeves’ muntjac can be a serious pest in gardens, conservation woodlands and sometimes in forestry. Regular coppicing of deciduous woodland, either to produce a crop of firewood or for conservation of other plants and animals, can be severely compromised. Because they breed all year, it is difficult to suggest a sensible humane culling season; and because they are so small, and often in suburban habitats, shooting is difficult. Bucks can be shot at any time, as can young does, before they have reached sexual maturity. In late pregnancy, when the previous fawn should be independent, it may again be acceptable to shoot does. Muntjac are strong, and push through quite dense barriers and under fences. Strong wire fences will stop them, especially if dug into the ground at the foot. Many muntjac are killed in vehicle collisions.

Identification

Small dog sized deer. Red/brown coat in summer, darker brown in winter. Only one or two are seen together. Dark rump with conspicuous white underside of tail that is seen when held vertical when alarmed. Antlers of mature male small single spikes pointing backwards. Males have distinctive tusks (upper canine teeth) that protrude just below the lip.

Footprints: Muntjac have the smallest footprints of all deer species. They are 2cm in width and 3-4cm in length.

Droppings: Deer droppings do not have obvious coloration or smell. The droppings tend to be of a similar shape across all species, although muntjac droppings are the smallest of all species.

Tail: The muntjac has a dark rump with a short tail with no stripes. It holds its tail up when alarmed, showing a white underside.

Confusion species

Chinese water deer (Hydropotes inermis)
Tail stumpy, never held upright as in muntjac (which holds it up to show the white underside when alarmed). No antlers in male, only long curved ‘tusks’ (upper canine teeth) protruding to around 7cm below lip. Muntjac male will also have protruding canine tusks, but are much shorter (around 2cm below lip) and will also usually have short, single spike, backward-pointing antlers. It is often said that the chinese water deer face looks like a teddy bear. Muntjac has two vertical stripes down the face, on the inside of each eye.

Roe deer (Capreolus capreolus)
Cream/white rump (oval shaped in males and upside down heart shape in females). No visible tail. Muntjac’s rump is same colour as rest of coat, but underside of tail is white, which is held upright when alarmed. Roe does not have any tusks (protruding upper canine teeth) whilst muntjac does. Roe has small pointed antlers, with no more than 3 points. Muntjac has single-spiked, backwards-pointing antlers which are not branched. Roe has distinctive black nose and white chin. Muntjac has two vertical stripes down the face, on the inside of each eye.
