Diet, Hunting and Feeding Behaviours

Prey animals in India include chital, sambar, muntjac, mouse deer, swamp deer, wild boar, gaur, water buffalo, banteng, cattle, nilgai, goats, Indian hares, Himalayan field rats and langurs. There is one record of a pack bringing down an Indian elephant calf in Assam, despite desperate defense of the mother resulting in numerous losses to the pack. In Kashmir, they may hunt markhor, and thamin in Burma. Javan rusas are hunted in Java. In the Tien Shan and Tarbagatai Mountains, dholes prey on Siberian ibexes, arkhar, roe deer, maral and wild boar. In the Altai and Sayan Mountains, they prey on musk deer and reindeer. In eastern Siberia, they prey on roe deer, Manchurian wapiti, wild boar, musk deer, and reindeer, while in Primorye they feed on sika deer and goral, too. In Mongolia, they prey on argali and rarely Siberian ibex. Like African wild dogs, but unlike wolves, dholes are not known to attack people. Dholes eat fruit and vegetable matter more readily than other canids. In captivity, they eat various kinds of grasses, herbs and leaves, seemingly for pleasure rather than just when ill. In summertime in the Tien Shan Mountains, dholes eat large quantities of mountain rhubarb. Bael fruits are also eaten. Although opportunistic, dholes have a seeming aversion to hunting cattle and their calves. Livestock predation by dholes has been a problem in Bhutan since the late 1990s, as domestic animals are often left outside to graze in the forest, sometimes for weeks at a time. Livestock stall-fed at night and grazed near homes are never attacked. Oxen are killed more often than cows are, probably because they are given less protection.

Before embarking on a hunt, clans go through elaborate prehunt social rituals involving nuzzling, body rubbing and homo- and heterosexual mounting. Dholes are primarily diurnal hunters, hunting in the early hours of the morning. They rarely hunt nocturnally, except on moonlit nights, indicating they greatly rely on sight when hunting. Though not as fast as jackals and foxes, they can chase their prey for many hours. During a pursuit, one or more dholes may take over chasing their prey, while the rest of the pack keeps up at a steadier pace behind, taking over once the other group tires. Most chases are short, lasting only 500 m. When chasing fleet-footed prey, they run at a pace of 30 mph. Dholes frequently drive their prey into water bodies, where the targeted animal's movements are hindered.

Once large prey is caught, one dhole will grab the prey's nose, while the rest of the pack pulls the animal down by the flanks and hindquarters. They do not use a killing bite to the throat. They occasionally blind their prey by attacking the eyes. Serows are among the only ungulate species capable of effectively defending themselves against dhole attacks, due to their thick, protective coats and short, sharp horns capable of easily impaling dholes. They will tear open their prey's flanks and disembowel it, eating the heart, liver, lungs and some sections of the intestines. The stomach and rumen are usually left untouched. Prey weighing less than 50 kg is usually killed within two minutes, while large stags may take 15 minutes to die. Once prey is secured, dholes will tear off pieces of the carcass and eat in seclusion. Unlike wolf packs, in which the breeding pair monopolises food, dholes give priority to the pups when feeding at a kill, allowing them to eat first. They are generally tolerant of scavengers at their kills.

Famous quotes containing the words hunting and/or feeding:

    Escape
    from the power of the hunting pack,
    and to know that wisdom is best
    and beauty
    sheer holiness.
    Hilda Doolittle (1886–1961)

    I am still a learner, not a teacher, feeding somewhat omnivorously, browsing both stalk and leaves; but I shall perhaps be enabled to speak with more precision and authority by and by,—if philosophy and sentiment are not buried under a multitude of details.
    Henry David Thoreau (1817–1862)
