Eastern Black Rhinoceros
Estimated Wild Population
Eastern black rhinoceroses stand up to five feet high at the shoulder, span 12 feet in length, weigh up to 3,000 pounds, and have two fibrous keratin horns. As a herbivorous browser, black rhinos primarily eat leafy plants, branches, shoots, thorny wood bushes, and fruit. Their skin harbors many external parasites, which are eaten by tickbirds and egrets that from a symbiotic relationship with the rhinos. Mating is non-seasonal and gestation lasts 15–16 months, after which a single calf is born. Newborns weigh about 75 pounds and are active soon after birth.
Interesting Fact 1
Despite their name, black rhinoceroses are closer to gray. They were named "black" as a juxtaposition to white rhinoceroses.
Interesting Fact 2
Their horn is used to make daggers and traditional medicine, which has led to rampant overhunting and a sharp decline in the wild population. In order to protect the species, the trade of their horns is now prohibited by international law.
Interesting Fact 3
Rhinos are notoriously difficult to breed at zoos, but a hormone-monitoring technique developed by Lincoln Park Zoo scientists has led to the birth of two calves since 2013.
