Wildlife of Sierra Leone
Sierra Leone has 15 identified species of primates that include bushbaby, monkeys and a great ape, the common chimpanzee which is Sierra Leone's largest primate. Chimpanzees are found across the country with the 2010 chimpanzee census estimated a wild population in excess of 5500 more than double the number previously thought to live in the country. This is the second largest population of the endangered subspecies of western chimpanzee, after Guinea,
with the largest density in the Loma area, 2.69 individuals per km2, and the Outamba, with 1.21 individuals per km2.
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.
