    Females probably first mate when about two years old and thus have their first calf at three years old 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, The gaur (ɡaʊər, Bos gaurus), also called Indian bison, is the largest extant bovine and is native to South Asia and Southeast Asia. The species is listed as vulnerable on the IUCN Red List since 1986,The gaur is a strong and massively built species with a high convex ridge on the forehead between the horns, 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 grey, or occasionally dirty white; the muzzle is pale coloured, and the lower part of the legs are pure white or tan.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 (28 to 41 in) long tail, and is 165 to 220 cm (5.41 to 7.2 ft) high at the shoulder. The average weight is 650 to 1,000 kg. Gaur historically occurred throughout mainland South and Southeast Asia, including Vietnam, Cambodia, Laos, China, Thailand, Peninsular Malaysia, Myanmar, India,Bangladesh, Bhutan, and Nepal.Where gaur have not been disturbed, they are basically diurnal. In other areas, they have become largely nocturnal due to forest molestation caused by people. In central India, they are most active at night,Wild gaur graze and browse on a wider variety of plants than any other ungulate species of India, with a preference for the upper portions of plants, such as leaf blades, stems, seeds and flowers of grass species, including kadam.In India, three major (Western Ghats, Central India and North-East) and two minor (Bihar and West Bengal) “Gaur conservation areas” have been identified, reflecting the remaining distribution (Sankar et al. 2000; Choudhury 2002). The Western Ghats and their outflanking hills in south India constitute one of the most extensive extant strongholds of Gaur, with good numbers in Wynaad — Nagarahole — Mudumalai — Bandipur complex (Ranjitsinh 1997).
