with each other in the wild. Along with lemurs, the Madagascar Forest exhibit houses the lemurs' main predator the fossa as well as the honey badger. Ethiopian Highlands The Ethiopian Highlands exhibit houses two primate species: the gelada and the Hamadryas baboon. The San Diego Zoo is only the second zoo in North America to house geladas, the other facility being the Bronx Zoo in New York City. Alpha male Juma leads the all-male members including Mahbub, Saburi, Abasi, Diwani, and Valentino. the group arrived at the Zoo on September 7, 2016, from the Wilhelma Zoo in Stuttgart, Germany where they lived with 44 other geladas. This move was based by the European Association of Zoos and Aquariums' (EAZA) European Endangered Species Programme (EEP) for geladas—the European equivalent of an Association of Zoos and Aquariums' (AZA) Species Survival Plan (SSP) program. The bachelor group will be introduced to females later on. The Ethiopian Highlands exhibit is also home to a troop of Nubian ibex. Kopje Woodland The word kopje in Dutch means "small head" which describes the rock formations that seem to pop out in the savanna. Kopjes are homes for well adapted animals. The San Diego Zoo's Kopje Woodland in Africa Rocks is home to animals including klipspringers, rock hyraxes, and the dwarf mongoose. Each animal has well adapted feet that allow them to cling to the rocks. The exhibit also includes southern ground hornbills and bateleur eagles, as well as meerkats, servals, trumpeter hornbills and the red-leaved rock fig, a tree species that manages to grow wherever its seeds disperse including the rocky kopje. West African Forest The West African Forest exhibits the dwarf crocodile. They are one of the smallest crocodile species, only measuring about in length. Behind the crocodile exhibit features Rady Falls, a tall waterfall, the largest man-made waterfall in San Diego. The west African exhibit also features Madagascan big-headed turtles, West African mud turtles, and the floating fig tree. All the exhibits house many rare and endangered species.
