Geographic Range
White-lipped deer are native to the Tibetan Plateau region of west central China.
- Biogeographic Regions
- palearctic
Habitat
Cervus albirostris
inhabit the high altitude rhododendron and coniferous forests and alpine meadows
of the Tibetan Plateau. Rough terrain and areas of high hunting pressure result in
a patchy distribution of these deer throughout their preferred habitats.
- Habitat Regions
- temperate
- terrestrial
Physical Description
White-lipped deer, as their name implies, have a characteristic pure white marking around their mouth and on the underside of the throat. The inner side of the legs and the underside of the body is also a whitish color. The overall coloration is dark brown during the summer and lightens during the winter. The fur, which lacks the typical undercoat hairs, is thick and course. A saddle-like appearance is created on the center of the deer's back, which is caused by the hair lying in the opposite direction. The fur coat is twice as long in the winter as it is during the summer.
Cervus albirostris
are one of the largest members of the deer family. Unlike other members of the family,
C. albirostris
have broad rounded hooves much like those of a cow. These hooves are specialized
for climbing on steep, rough terrain. Females have a tuft of hair between their narrow,
lance shaped ears. The 5 to 6 pointed antler rack of males protrudes forward and is
flattened, like those of caribou. The white colored (rarely light brown) rack can
weigh up to 7 kilograms and reach l.3 meters.

Reproduction
Most of the year, males and females travel in separate herds. During the breeding season, or rut, around October through November, males intermingle with female herds. Mixed herds at the peak of the mating season have been reported to range between 50 and 300 deer. Males expend large amounts of energy during the breeding season in mating and in male-male aggressive encounters. Most males lose weight during this period. Males compete amongst themselves for access to females.
- Mating System
- polygynous
White-lipped deer are born from May through late June. The well developed baby stays with its mother and is not weaned for at least 10 months.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- viviparous
Young white-lipped deer, which are able to stand only a half hour after birth, stay
and travel with their mothers in female herds. Two to three days after birth, the
mother will take her fawn into a more sheltered area away from the birth place. The
baby is left to rest at times but is never out of the mother's sight. If she sees
that something is near the baby, the mother will attempt to cause a distraction by
running in the opposite direction. After the fawn is weaned at about 10 months of
age, it joins the sex-segregated herds. Young males move to the male herd, young females
stay in the herd in which they were raised and travel with their mothers, though they
are no longer dependent upon them.

Lifespan/Longevity
White-lipped deer have been recorded living 19 years in captivity. Many people in
China are raising these deer on farms and they are kept in zoos for public display.
Those in the wild may for 16 to 18 years.
Behavior
Cervus albirostris
are most active during the day. They are most often found in high, remote areas where
human influence is minimal. They travel in herds, in groups separated by gender and
age much like red deer (
Cervus elaphus
). Juvenile males travel as one small group. Females who are pregnant, those still
nursing their young, and pre-adult females travel in another group. Older males travel
alone. During the mating season mixed-sex groups occur.
- Key Behaviors
- cursorial
- terricolous
- diurnal
- motile
- social
- dominance hierarchies
Communication and Perception
Food Habits
White-lipped deer are exclusively herbivorous. They graze mainly on grasses but will
also eat other foliage.
Foods eaten include: grasses mainly
Stipa
,
Kobresia
, and
Carex
spp., sedges and herbs.
- Plant Foods
- leaves
- wood, bark, or stems
Predation
White-lipped deer are herd animals and, therefore, rely upon the vigilance of every
herd member in detecting predators. They are fast and agile runners and can defend
themselves with their sharp hooves. Female white-lipped deer will attempt to distract
predators from their young by causing a disturbance and running away from where the
fawn is hidden.
Ecosystem Roles
White-lipped deer play an important role as prey animals for large predators. They
also limit vegetation growth and determine vegetative structure through their grazing.
Economic Importance for Humans: Positive
Aside from being hunted as a food source by Chinese and Tibetan peoples,
Cervus albirostris
are poached for their enormous antlers. The antlers and other body parts are used
as a source of oriental medicine.
- Positive Impacts
- food
- source of medicine or drug
Economic Importance for Humans: Negative
There are no known negative effects of white-lipped deer.
Conservation Status
According to a team studying in the Tibetan Plateau, numbers of
Cervus albirostris
may be increasing. This team assessed population sizes during the periods of 1990-1992
and 1997. They observed 80-89 deer during September of 1997, compared to only 16
(no more than 50) in early 1990's. This species is otherwise thought to be extremely
endangered and rare.
Other Comments
Cervus albirostris
is known as "shor" by the Tibetan people. The species was discovered and named by
Przewalski during the later 1870's. W. G. Thorold later described the same deer,
not knowing that it had already been described, he named it Thorold's deer,
Cervus thoroldi
, in 1891.
