It is one of the species in most danger of extinction. Its decline is due not only to the impact of man but to its apparent inability to extend its range into areas where rhinos have not formerly existed. which will only survive in sanctuaries where its interests are paramount. Warning is given of the urgent need for strict measures to concerve the species.

Poaching of the species in Kenya is carried out largely by means of poisoned arrows or leg snares. Instances have been recorded of black rhinoceroses being killed by elephants ( Loxodonta africana Blumenbach) and by lions ( Panther a leo Linnaeus).Īn account is given of the structure of the horns and the way in which they are used. The disposition of individual animals is considered to be related to the degree to which they have been persecuted by man in different areas, inhabited by hunting or pastoral tribes, a marked difference in behaviour is apparent. Mating may take place at any time during the year. A constant behaviour pattern during defaecation and urination is described.Ī group or herd is usually composed of one, two or three individuals. In order to feed it may move 5–15 miles from the watering place along regular paths feeding takes place in the early morning and evening and the remainder of the day is spent resting in shaue.

somaliensis Potocki.ĭaily activity and home range of the black rhinoceroy are largely related to its water requirements. It is described in detail with comments on the validity of the two subspecies D. This species, which is adapted to a wide range of habitats, is now absent from or scarce in many parts of Africa where it was common only 50 or 100 years ago. The two African genera of rhinoceroses are briefly compared and an account given of the distribution of the black rhinoceros ( Diceros bicornis L.).
