The Leopard (Panthera pardus) is the other large cat found in Corbett. Compared to the tiger leopards are smaller, more graceful and have a long agile body that has rosettes instead of stripes. It also has the ability to limb trees. Leopards are quite versatile, adaptable to a variety of terrains as well as to a broad range of prey that includes everything from insects and rodents up to large ungulates. Leopards mostly hunt during twilight hours and at night. They also ambush their prey by jumping down from trees.
The leopard’s call is termed as ‘saw’. Sawing can be described as a short rasping vocalisation.
When living near populated areas leopards will attack and kill livestock and domestic dogs. Sometimes, they also attack humans.
In spite of leopards being highly adaptable, they face many problems in survival. This includes habitat destruction, poaching for their skins, and persecution as killers.
There are two species of primates found in Corbett. The Rhesus Macaque (Macaca mulatta) is the commonest monkey of the Indian subcontinent. It lives in a wide range of habitats – from plains to the Himalayas at elevations up to 3000 m – and is quite adaptable to humans. Its body is earthy brown in colour and buttocks are reddish. The Rhesus is quite a lively and vocal animal. It lives in large troupes of up to two hundred individuals. Large dominant males (called alpha males) lead these groups. It is omnivorous, and often eats roots, herbs, fruits, insects, crops, and small animals.
Hanuman or Common Langur (Semnopithecus entellus) has an unmistakable appearance - a light body, dark face and a very long tail. It is considered to be sacred in many parts of India and is found in many environments, from desert edge to forests.
Langurs are vegetarian and feed mainly on leaves, buds, flowers, fruit, and seeds. Feeding activity is generally in the early morning and late afternoon.
Like monkeys, langurs too live in troupes led by dominant males. In the trees, they are remarkably agile and can make horizontal leaps of 3-5 m.
Himalayan Goral or Ghural (Nemorhaedus goral) is a goat-like animal that occurs in the Himalayas between 1,000 to 4,000 m. It lives in small groups on sparse mountainous slopes and cliff faces with crevices. It is remarkably sure footed and can move at high speeds even over near vertical terrain. Goral are active at dawn and dusk when they come to feed on grasses, leaves, twigs, nuts and fruit.
Mostly grey to brown in colour, the goral has a lighter coloured ‘bib’ at the base of the neck and sports short, conical, backward-curving horns having irregular ridges. Goral are well camouflaged, and thus are very difficult to spot, especially when they are still.
Wild boar (Sus scrofa) is the ancestor of the domesticated pig that lives in moist forests and scrub. It has long, curved canine teeth (called tusks) that are used for digging food and as weapons. Wild boar feed on roots, tubers, fruits, shrubs, bird eggs, insects, mice, snakes, frogs and carrion. They usually move in groups both at day and night.
The Asiatic Jackal (Canis aureus) is a member of the dog family. It is found in open country, short grasslands and has also adapted to living near human settlements.
It comes out during the night to forage for food. Its omnivorous diet consists of deer fawns, rodents, hares, birds, eggs, reptiles and amphibians and various fruits especially ber and jamun. The jackal is also an opportunistic scavenger, readily raiding garbage bins.
Corbett is one of the few places in India where three species of otter are found existing together. Otters are an important component in the ecology of the Park, especially the Ramganga and its tributaries. Otters are indicators of a healthy river ecosystem. These small carnivores are a part the aquatic food chain and live mostly along riverbanks, spending a lot of their time in water. They make dens among rocks and boulders along perennial streams and rivers.
The species of otters occurring in Jim Corbett National Park are Eurasian or Common otter (Lutra lutra monticola), Smooth-coated otter (Lutra perspicillata) and Small-clawed otter (Aonyx cinerea). Fish forms the majority of the otters’ diet, except in case of Small-clawed otter, which primarily feeds on insects and other invertebrates.
Otters face threat of elimination of habitat due to construction of dams, intensive fishing, quarrying in rivers for stone and gravel and land use changes for agriculture or prawn cultivation. Poaching in the hilly regions of India for otter skins is also a threat.
