About Southern Black Rhinoceros
Fossil Rim participates in the International Rhino Foundation’s Southern Black Rhino Sustainability Program, which is a coordinated international effort to establish and maintain a viable population in captivity to save the species.
In addition to breeding, Fossil Rim is participating in research that will hopefully help increase the world’s dwindling population. While strict laws prohibit hunting to protect black rhinos, poaching continues to be a problem. Even in national parks and reserves, enforcement of those laws is difficult given the availability of automatic weapons in the region and ever-higher prices for rhino horn.
The black rhino horn is not a true horn, and it is made of dense fibers similar to material in fingernails. It can range from to 1.5-4 feet in length. The horn is not attached to the skull, but rather grows from the skin.
Rhinos are poached for their horns, which in powdered form is a popular ingredient in traditional Asian medicines. More recently, the horn has become a status symbol of the wealthy. There is no scientific evidence of rhino horn’s medicinal value, but the poaching continues.
A dehorning program was attempted in the hopes of making the rhino worthless to poachers. Unfortunately, poachers continued killing rhinos in the hopes of increasing the value of the horns they already had in possession and to prevent them from tracking those rhinos again.
The word “rhinoceros” is derived from the Greek rhino (nose) and ceros (horn). Like the white rhino, the black rhino is actually gray and has two horns. However, the black rhino has a pointed, prehensile upper lip, which distinguishes it from the white rhino.
One of the largest land animals, black rhinos are extremely agile for their size and can reach speeds of 30 mph when charging. Although they have poor eyesight, their hearing is acute. Black rhinos have long, tube-shaped ears that act as funnels for sound. They can swivel their ears in all directions, picking up noises from great distances.
Their sense of smell is superb and is their primary method of detecting danger. Black rhino calves weigh 55-90 pounds at birth and stay with their mothers for up to three years.
Extremely possessive, their home territory always includes at least one water hole and a mud wallow. The boundaries are defined by urine sprayed on bushes and middens (dung heaps) left by the male at regular intervals.
The males scatter the dung with their horns and hind feet to form middens about 72 inches wide. The probable reason for this is to warn other males they are trespassing and also to advertise their own presence to single females who may thus be encouraged to enter their territory.
The black rhino is not as solitary as it is often thought to be. Males may tolerate other males, as long as they remain submissive, and females sometimes allow an unrelated juvenile to accompany her and a calf.
There were approximately 5,000 black rhinos in Africa as of 2019, which includes the eastern, south central, and southwestern subspecies. The black rhinos at Fossil Rim can be viewed on the Behind-the-Scenes Tour.
