or mithun.

The Malayan gaur is called seladang, and the Burmese gaur is called pyoung.


The gaur has a head-and-body length of 250 to 330 cm (8.2 to 10.8 ft) with a 70 to 105 cm (27.6 to 41.3 in) long tail, and is 165 to 220 cm (5.4 to 7.2 ft) high at the shoulder. Weight is 650 to 1000 kg (1,433 to 2,204.6 lb). Males are about one-fourth larger and heavier than females. Body weight may reach 1500 kg (3,306.9 lb).

The gaur has a high convex ridge on the forehead between the horn

s, which bends forward, causing a deep hollow in the profile of the upper part of the head. There is a prominent ridge on the back. The ears are very large; the tail only just reaches the hocks, and in old bulls the hair becomes very thin on the back. In colour, the adult male gaur is dark brown, approaching black in very old individuals; the upper part of the head, from above the eyes to the nape of the neck, is, however, ashy gray, or occasionally dirty white; the muzzle is pale coloured, and the lower part of the legs are pure white or tan. The cows and young bulls are paler, and in some instances have a rufous tinge, which is most marked in individuals inhabiting dry and open districts.

The tail is shorter than in the typical oxen, reaching only to the hocks. The animals have a distinct ridge running from the shoulders to the middle of the back; the shoulders may be as much as 12 centimetres (4.7 in) higher than the rump. This ridge is caused by the great length of the spinous processes of the vertebrae of the fore-part of the trunk as compared with those of the loins. The hair is short, fine and glossy, and the hooves are narrow and pointed.

Horns grow to a length of 60 to 115 cm (23.6 to 45.3 in). Both sexes carry horns, which grow from the sides of the head, curving upwards. They are regularly curved throughout their length, and are bent inward and slightly backward at their tips. The colour of the horns is some shade of pale green or yellow throughout the greater part of their length, but the tips are black. A bulging grey-tan ridge connects the horns on the forehead. The horns are flattened to a greater or less degree from front to back, more especially at their bases, where they present an elliptical cross-section; this characteristic is more strongly marked in the bulls than in the cows.

Gaur have highly muscular bodies, with distinctive dorsal ridges and large dewlap

They are largely confined to evergreen forests or semi-evergreen and moist deciduous forests, but also occur in dry deciduous forest areas at the periphery of their range. Gaur habitat is characterized by large, relatively undisturbed forest tracts, hilly terrain below an altitude of 5000 to 6000 ft (1,524 to 1,828.8 m), availability of water, and an abundance of forage in the form of grasses, bamboo

, shrubs, and trees. Their apparent preference for hilly terrain may be partly due to the earlier conversion of most of the plains and other low-lying areas to croplands and pastures. They occur from sea level up to at least 2800 m (9,186.4 ft) altitude. Low-lying areas seem to comprise optimal habitat.

Ecology and behaviour

Where gaur have not been disturbed, they are basically diurnal

Diurnality is a plant or animal behavior characterized by activity during the day and sleeping at night.-In animals:Animals that are not diurnal might be nocturnal or crepuscular . Many animal species are diurnal, including many mammals, insects, reptiles and birds...

. In other areas, they have become largely nocturnal due to molestation by people. In central India, they are most active at night, and are rarely seen in the open after 8 o'clock in the morning. During the dry season, herds congregate and remain in small areas, dispersing into the hills with the arrival of the monsoon
Monsoon is traditionally defined as a seasonal reversing wind accompanied by corresponding changes in precipitation, but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea...

. While gaur depend on water for drinking, they do not seem to bathe or wallow.

In January and February, gaur live in small herds of eight to 11 individuals, one of which is a bull. In April or May, more bulls may join the herd for mating, and individual bulls may move from herd to herd, each mating with many cows. In May or June, they leave the herd and may form herds of bulls only or live alone. Herds wander 2–5 km (1.2–3.1 mi) each day. Each herd has a nonexclusive home range, and sometimes herds may join in groups of 50 or more. The average population density is about 0.6 animals per square kilometre (1.5 animals per square mile), with herds having home ranges of around 80 square kilometres (30.9 sq mi).

Gaur herds are led by an old adult female (the matriarch). Adult males may be solitary. During the peak of the breeding season, unattached males wander widely in search of receptive females. No serious fighting between males has been recorded, with size being the major factor in determining dominance. Males make a mating call of clear, resonant tones which may carry for more than 1.6 kilometre (0.994196378639691 mi). Gaur have also been known to make a whistling snort as an alarm call, and a low, cow-like moo.

In some regions in India where human disturbance is minor, the gaur is very timid and shy. When alarmed, gaur crash into the jungle at a surprising speed. However, in Southeast Asia

 and South India, where they are used to the presence of humans, gaur are said by locals to be very bold and aggressive. They are frequently known to go into fields and graze alongside domestic cattle, sometimes killing them in fights. Gaur bulls may charge unprovoked, especially during summer, when the heat and parasitic insects make them more short-tempered than usual. To warn other members of its herd of approaching danger, the gaur lets out a high whistle for help.

Due to their formidable size and power, gaur have few natural enemies. Leopard

A herd of gaur in Malaysia encircled a calf killed by a tiger and prevented it from approaching the carcass. In Nagarahole National Park, upon sensing a stalking tiger, a herd of gaur walked as a menacing phalanx towards it, forcing the tiger to retreat and abandon the hunt. Gaur are not as aggressive toward humans as wild Asian water buffalo

There are several cases of tigers being killed by gaur. In one instance, a tiger was repeatedly gored and trampled to death by a gaur during a prolonged battle. A large male tiger carcass was found beside a small, broken tree in Nagarahole National Park, having been fatally struck against the tree by a large bull gaur a few days earlier.

. In summer, they also feed on bark of teak, on fruit of golden shower tree, and on the bark and fruit of cashew. Gaur spent most of their daily time feeding. Peak feeding activity was observed between 6:30 and 8:30 am and between 5:30 and 6:45 pm. During the hottest hours of the day, 1:30 to 3:30 pm, they rest in the shade of big trees.

They may debark trees due to shortages of preferred food, and of minerals and trace elements needed for their nutrition, or for maintaining an optimum fiber/protein ratio for proper digestion of food and better assimilation of nutrients. They may turn to available browse species and fibrous teak bark in summer as green grass and herbaceous resources dry up. High concentrations of calcium (22400 ppm) and phosphorus (400 ppm) have been reported in teak bark, so consumption of teak bark may help animals to satisfy both mineral and other food needs. Long-term survival and conservation of these herbivores depend on the availability of preferred plant species for food. Hence, protection of the historically preferred habitats used by gaur is a significant factor in conservation biology

Gaur have one calf (or occasionally two) after a gestation period of about 275 days, about nine months, a few days less than domestic cattle. Calves are typically weaned after seven to 12 months. Sexual maturity occurs in the gaur's second or third year. Breeding takes place year-round, but typically peaks between December and June. The lifespan of a gaur in captivity is up to 30 years.
