Behavioral Research
Understanding chimpanzee behavior to improve captive care and conservation
Our research partnerships advance evidence-based chimpanzee welfare and conservation.
Facilitating Global Research
Ngamba Island Chimpanzee Sanctuary serves as a globally recognized hub for non-invasive behavioral studies. The unique semi-natural environment of our island forest allows researchers to observe primate social dynamics, tool-use, conflict resolution, and cognition exactly as they occur in complex societies.
Strictly Non-Invasive
We strictly enforce a non-invasive protocol. All research is purely observational. The psychological and physical welfare of the 53 rescued chimpanzees is paramount — studies never create stress or disrupt daily routines.
International Partnerships
The Trust partners with renowned universities and researchers worldwide, contributing to groundbreaking peer-reviewed journals and expanding collective understanding of our closest relatives.
Research Areas
Cognition & Problem Solving
Studies on tool use, spatial reasoning, and cognitive flexibility in semi-natural environments.
Social Dynamics
Hierarchy formation, alliance building, conflict resolution, and grooming networks within the troop.
Behavioral Ecology
Foraging strategies, nest construction, communication, and daily activity budgets in island forest habitat.
Welfare Science
Indicators of wellbeing, stress response research, enrichment effectiveness, and rehabilitation outcomes.
2025 Publications & Research Outputs
Ngamba Island Chimpanzee Sanctuary is a globally recognized research station for non-invasive behavioral and cognitive studies. In 2025 alone, studies conducted with our resident chimpanzees yielded groundbreaking discoveries published in Science, Proceedings of the Royal Society B, and major academic dissertations.
Chimpanzees rationally revise their beliefs
This landmark study conducted at Ngamba Island Sanctuary proved that chimpanzees can rationally update their choices based on the quality and strength of new evidence — demonstrating cognitive flexibility once thought to be unique to human thought.

This landmark study showed that chimpanzees can rationally revise their beliefs based on the quantity and quality of new evidence — a hallmark of rational thought once considered uniquely human. In experiments with two boxes (one containing food), chimps received an initial hint about the reward location, then a stronger contradictory clue; many flexibly switched their choice. Computational modeling ruled out simpler explanations like recency bias.
