Badak (Rhinocerus)
Rhinos live in home ranges that sometimes overlap with each other. Feeding grounds, water holes and wallows may be shared. The black rhino is usually solitary. The white rhino tends to be much more gregarious. Rhinos are also rather ill-tempered and have become more so in areas where they have been constantly disturbed. While their eyesight is poor, which is probably why they will sometimes charge without apparent reason, their sense of smell and hearing are very good. They have an extended "vocabulary" of growls, grunts, squeaks, snorts and bellows. When attacking, the rhino lowers its head, snorts, breaks into a gallop reaching speeds of 30 miles an hour, and gores or strikes powerful blows with its horns. Still, for all its bulk, the rhino is very agile and can quickly turn in a small space. The rhino has a symbiotic relationship with oxpeckers, also called tick birds. In Swahili the tick bird is named "askari wa kifaru," meaning "the rhino's guard." The bird eats ticks it finds on the rhino and noisily warns of danger. Although the birds also eat blood from sores on the rhino's skin and thus obstruct healing, they are still tolerated.

The closest rhino relationship is between a female and her calf, lasting from 2 to 4 years. As the older calves mature, they leave their mothers and may join other females and their young, where they are tolerated for some time before living completely on their own.
