A critically endangered black rhinoceros calf named Ajubu tried out his legs at the San Diego Zoo's Wild Animal Park, August 26, 2004. The 9-day-old male kept up with his first-time mother as she dashed around their habitat. An adult male, Jambia, which was the last black rhino to be born at the Wild Animal Park seven years ago, sired the rambunctious calf. To date, 10 black rhinos have been born at the Park. Black rhinoceros are now only found in small pockets of eastern and southern Africa, numbering at a mere 3,600. In 1970, there were 65,000 black rhinos throughout larger areas of Africa, but poaching and loss of habitat have caused a devastating decline in the population of all five rhino species.

Kenya Wildlife Service rangers dehorn a black rhino using a chainsaw in the Nairobi National Park June 24, 1996. The rhino was dehorned so it wouldn't injure itself while traveling in a crate. The horn will grow back at a rate of 2 inches a year. Park rangers moved four rhinos on June 20 and four more on June 24 from Nairobi, where the population is booming to Tsavo National Park to rebuild a herd that was nearly wiped out by poachers in the 1980s.
