Eastern gorilla
The eastern gorilla ("Gorilla beringei") is a critically endangered species of the genus "Gorilla" and the largest living primate. At present, the species is subdivided into two subspecies. Grauer's gorilla, formerly known as the eastern lowland gorilla ("G. b. graueri") is more populous, at about 3,800 individuals. The mountain gorilla ("G. b. beringei") has only about 1000 individuals. The International Union for the Conservation of Nature mentioned illegal hunting in its assessment of threats to the species.
Bronx Zoo
Baboon Reserve, opened in 1990, is a two-acre recreation of the Ethiopian highlands which, at the time of its opening, was the largest primate exhibit in the United States. The exhibit's main features revolve around the zoo's troop of geladas such as artificial rocks and earthbanks, and displays about life in the highlands and the side-by-side evolution of humans and geladas. Visitors can watch the geladas from multiple viewpoints along with Nubian ibex and rock hyrax, all of which are mixed together in the hilly enclosure. An African village-styled café overlooks the exhibit. Baboon Reserve won the AZA Exhibit Award in 1991. In the fall of 2014, a male gelada was born at the zoo, the first in over 13 years.
