Axis axis
chital


By Barbara Lundrigan and Carry Gardner

Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Artiodactyla
Family: Cervidae
Genus: Axis
Species: Axis axis

Geographic Range

The axis deer occurs historically in India and Ceylon. They have been introduced to Texas and Hawaii.

Biogeographic Regions
nearctic (Introduced ); oriental (Native )

Habitat

In their native lands, the deer occupy grasslands and very rarely move into areas of dense jungle that may occur adjacent to them. Short grasslands are an important area for them due to a lack of cover for predators such as the tiger (Moe and Wegge, 1994). Riverine forests within the Bardia National Park in lowland Nepal are highly utilized by the deer for shade and cover during the dry season. The forest also provides good foraging with regard to fallen fruit and leaves that are high in nutrients needed by the deer. Therefore, the deer require open areas as well as forested areas within their home ranges for optimum habitat. Their total range incorporates a core area of about 32 hectares(ha) surrounded by foraging and cover areas of about 140 ha for females and 195 ha for males (Moe and Wegge, 1994). Some variation in range size occurs depending on the season as well as the sex.

Habitat Regions
tropical ; terrestrial

Terrestrial Biomes
savanna or grassland

Other Habitat Features

Physical Description

Range mass

(59.47 to 99.12 lb)

The Axis deer stands 0.6 to 1 m tall at the shoulder and has a body length of about 1.5 m (Walker, 1964). The body color is reddish with white on the belly, inner legs, and underneath their short tail. The males tend to be darker and to have black facial markings. They also have antlers composed of three tines which can reach lengths of almost a meter. Characteristic white spots occur in both sexes and run longitudinally in rows throughout the duration of the animal's life (Ables,1977). A dark dorsal stripe runs the length of the animal's back. (Albes, 1977; Walker, 1964)

Other Physical Features
endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism
sexes colored or patterned differently; ornamentation

Reproduction

Males tend to bellow during the mating season which may be a good indicator of when breeding begins. (Walker, 1964)

Breeding interval
Axis deer breed once yearly.

Breeding season
Breeding occurs in April and May.

Axis deer breed in April or May and have a gestation of about 7.5 months. They usually have two fawns but one or three is not uncommon(Walker, 1964). The number of fawns produced as well as the mating season may vary for deer in captivity; only one fawn is usually produced and mating may take place from May to August (Ables, 1977). First pregnancies usually occur between the ages of 14 to 17 months. The female usually maintains nursing until the fawn can safely roam with the herd (Walker, 1964).

Key Reproductive Features
iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); fertilization (Internal ); viviparous

Behavior

Axis deer occur in several different kinds of herds depending on their age and sex. Matriarchal herds are common and composed of adult females and their young from the present and previous year. Sexually active males follow these groups during the mating season while less active males form bachelor herds. One other type of herd that occurs frequently are called nursery herds which include females with fawns less than 8 weeks old. The males participate in a dominance-based hierarchial system where older and larger males dominate younger and smaller males. There are four different aggressive displays among males; head-down or scare threat, present threat, head-up, and antler threat. Females also partake in aggressive behavior but it is mostly associated with over-crowding at feeding sites. Biting, striking, and chasing are the behaviors most commonly seen among females and occasionally between females and other sexes and age classes (Ables, 1977). (Albes, 1977)

Key Behaviors
terricolous; diurnal ; nomadic ; social ; dominance hierarchies

Communication and Perception

Axis deer have several vocalizations besides the bellowing that occurs during the mating season. They have a bark that is used during times of alarm or when an unusual object has been observed. This usually occurs among females and juveniles and is repeated back and forth. Another kind is squealing which is used by fawns when they get separated from their mothers. Moaning is associated with males during aggressive displays or when resting (Ables, 1977).

Communication Channels
visual ; tactile ; acoustic ; chemical

Perception Channels
visual ; acoustic

Food Habits

The main foods utilized by these deer are grasses as well as flowers and fruits which fall from the forest trees. They will occasionally browse when it is necessary. During the monsoon season, grass and sedge species in a sal forest are an important food source. Another source of nutrition may come from mushrooms which are high in proteins and nutrients and are also found in sal forests (Moe and Wegge, 1994). (Moe and Wegge, 1994)

Plant Foods
leaves; wood, bark, or stems; fruit

Economic Importance for Humans: Positive

Axis deer have become an important resource for hunting in the United States.

Conservation Status

IUCN Red List [Link]
Lower Risk - Least Concern

US Federal List [Link]
No special status

CITES [Link]
No special status

The axis deer has been introduced into Texas and Hawaii with good results. They do very well in captivity and can be seen at Zoos in the United States. Most are on private lands in the U.S., however, some are free-ranging.
