Research sites

We partner with several parks, sanctuaries, and research centers in the US, Europe, and Africa. This allows us to study primates living in socially and ecologically-rich environments, and understand their cognition and behavior in natural contexts.


Ngamba Island
  • Population: ~50 wild-born chimpanzees (Pan troglodytes)
  • Location: In Lake Victoria near Entebbe, Uganda
  • Setting: Ngamba Island Chimpanzee Sanctuary cares for wild-born orphans of the bush-meat and pet trade. During the day, chimpanzees free-range on an island of over 90 acres of primary tropical rain forest located in Lake Victoria. We conduct research in the apes’ sleeping dormitory.

Tchimpounga
  • Population: ~140 wild-born chimpanzees (Pan troglodytes)
  • Location: near Pointe Noire, Republic of Congo
  • Setting: Tchimpounga, overseen by the Jane Goodall Institute, cares for wild-born orphans of the bush-meat and pet trade. Chimpanzees live in several mixed-age and -sex groups that free-range in tropic rinforest enclosures or islands. We conduct research in the apes’ sleeping dormitories.

Trentham Monkey Forest
  • Population: ~140 Barbary macaques (Macaca sylvanus)
  • Location: near Stoke-on-Trent, UK
  • Setting: Barbary macaques at Trentham comprise two mixed-sex groups that semi-free-range in a 60 acre forested park. The monkeys are a cold-adapted species and can live outside comfortably year-round. We approach calmly-sitting monkeys as they move about the forest to conduct cognitive studies and do behavioral observations.

Cayo Santiago Field Station
  • Population: ~1700 rhesus macaques (Macaca mulatta)
  • Location: Near Punta Santiago, Puerto Rico
  • Setting: This population of monkeys was introduced to Cayo Santiago in the 1930s. The Cayo Santiago Field Station is now one section of the Caribbean Primate Research Center. Monkeys free-range through the island’s 38 acres, living in natural multi-male multi-female social groups. We approach calmly-sitting monkeys to conduct our studies.

Duke Lemur Center
  • Population: ~250 lemurs from 20+ species, including Coquerel’s sifaka (Propithecus coquereli), ruffed lemurs (Varecia sp.), ringtailed lemurs (Lemur catta),and mongoose lemurs (Eulemur mongoz).
  • Location: Durham, NC USA
  • Setting: This is the largest collection of these highly-endangered primates in the world. Lemurs live in species-appropriate social groups, and many free-range in 80 acres of Duke forest during the warmer months.

Lola ya Bonobo
  • Population: ~65 wild-born bonobos (Pan paniscus)
  • Location: Outside Kinshasa, Democratic Republic of Congo
  • Setting: Lola ya Bonobo Sanctuary cares for wild-born orphans of the bush-meat and pet trade. During the day, bonobos free-range in large forested enclosures in their social groups. We conduct research in the apes’ sleeping dormitories.
