onto plains only if there is a large abundance of bushes, but normally avoid such open areas to avoid becoming an easy target for their predators. Their diet consists of leaves, grass, shoots and occasionally tubers, roots and fruit (they are especially fond of oranges and tangerines). During the day, greater kudus normally cease to be active and instead seek cover under woodland, especially during hot days. They feed and drink in the early morning and late afternoon, acquiring water from waterholes or roots and bulbs that have a high water content. Although they tend to stay in one area, the greater kudu may search over a large distance for water in times of drought, in southern Namibia where water is relatively scarce they have been known to cover extensive distances in very short periods of time. Predation Predators of the greater kudu generally consist of lions, spotted hyenas, and African wild dogs. Although cheetahs and leopards also prey on greater kudus, they usually target cows and calves rather than fully grown bulls. There are several instances reported where Nile crocodiles have preyed on greater kudus, although based on records, the larger mammalian carnivores statistically are much more dangerous to the kudu and comparable large ungulates, or at least those with a preference for dry, upland habitats over riparian or swamp areas. When a herd is threatened by predators, an adult (usually a female) will issue a bark to alert the rest of the herd. Despite being very nimble over rocky hillsides and mountains, the greater kudu is not fast enough (nor does it have enough endurance) to escape its main predators over open terrain, so it tends to rely on leaping over shrubs and small trees to shake off pursuers. Greater kudus have excellent hearing and acute eyesight, which helps to alert them to approaching predators.Their colouring and markings protect kudus by camouflaging them. If alarmed, they usually stand still, making them very difficult to spot. Behavior and social organization Greater kudus have a lifespan of 7 to 8 years in the wild, and up to 23 years in captivity. They may be active throughout the 24-hour day. Herds disperse during the rainy season when food is plentiful. During the dry season, there are only a few concentrated areas of food so the herds will congregate. Greater kudu are not territorial; they have home areas instead. Maternal herds have
