Black Rhino

There are five species of rhinos—all of which are endangered. Here at the Caldwell Zoo, we have black rhinos. Black rhinos are primarily solitary while other species, such as white rhinos live in herds. These rhinos possess a prehensile lip, which allows them to pluck leaves off of bushes and shrubs of their choice.

Black rhinos rely on their sense of hearing and smell. Since they have poor vision they rely on warning calls from other animals and are sometimes seen charging trees and termite mounds. Their special horns are made of keratin, which is the material found in human fingernails and hair. Rhinos are heavily poached for their horns, which are used in traditional medicine in Asian countries and as a status symbol.

Kizuri, whose name means “beauty,” came to the Caldwell Zoo from the Brookfield Zoo in Chicago, IL. She was born May 15, 1998. Although Kizuri seems to be the shyest of our rhinos, she gets rather jealous when the zookeepers are feeding or working with other rhinos. She will snort to make sure she gets her share of attention.


Christa, one of Caldwell Zoo’s female black rhinoceros, was born at the San Antonio Zoo on February 1, 1986. While at Caldwell Zoo, she has been mom to four youngsters—Ebony, born in 1993; Tatu, born in 1997; Jumbe, born in 2003; and Pnineus, born in 2007. Although Christa does not like rainy days she does love to drink from a water hose. Her favorite treat is sweet potato. The zookeepers who care for Christa affectionately call her “The Princess” since she is rather particular about her environment.
