The Big 5 of africa

Rhino black

Diceros bicornis

Also known as the hook-lipped rhino due to its prehensile upper lip there is in fact no difference in colour to the white rhino. It is considered the more aggressive of the two species and is the original member of the big five among the rhino's.

Distribution Once found throughout southern, central and East Africa black rhino numbers have shrunk dramatically since the 1960s (mainly due to poaching). The only black rhino populations in existence can be found in conservation areas and national parks in Kenya, Tanzania, South Africa, Zimbabwe and Namibia.

Social structure Solitary creatures but individuals may gather at waterholes; bulls and cows will only come together to mate. A calf will accompany the mother until her next birth. They do establish home ranges that overlap with each other. The sizes of the home ranges depend on the availability of food and water.

Range differentiation Differences between areas of occurrence have been nullified with the trans-location of individual animals from area to area.

Habitat Found in arid and wet regions where shrubs and smaller trees provide food and shade. They need to drink water, however in drier areas they may only slake their thirst every five days.

Feeding Generally browsers although they are known to graze new grass. In the Ngorongoro Crater grass forms a large part of their diet. The prehensile upper lip is used to grasp leaves and twigs. The horns are used to break off branches and twigs out of reach of the mouth.

Breeding Calves are born throughout the year after a gestation period of about eighteen months. The calf can walk and suckle within hours of birth. When on the move, the calf walks behind the mother or at times alongside her.

Black rhino - more agressive than the white rhino

Black rhino are considered more aggressive than the white rhino.

Rhino enjoy a good mud wallow as it cools them down.

Rhinos have poor eyesight but a good sense of hearing. When they hear a sound they often trot closer to inspect. It is because of this that they have the reputation for charging at every sound. Mere inquisitiveness has often been mistaken for a charge.

Rhinos communicate by means of bellows, squeaks and snorts depending on the occasion.

In the Far East, rhino horn is believed to have aphrodisiac properties. This may stem from the fact that a male will stay mounted on a female for extended periods. The horn is made up of compressed hair. In Yemen, rhino horn is prized as a dagger handle where it is a sign of manhood and virility.
