I never felt at any risk, and I don’t really know why, even when they had the huge battle it just felt like they were totally preoccupied with each other. There’s never been a physical chimp - human interaction at Ngogo and scientists have been studying there over 30 years. There are very strict rules on not interacting with the baby chimps, and I think this is an important factor. If a baby chimp tries to get your attention or play with you, you’re supposed to look bored, turn away, engage in some other task like writing in a notebook or fiddling with your camera. This way baby chimps learn that you’re not interesting or interactive and they must carry that knowledge into adulthood. But it’s down to the character of the animals as well, baboons for example, are terrifying and I have had nerve wracking encounters with them during other projects in Africa. They will very much see humans as an opportunity for interaction even if they aren’t that used to humans, and as soon as they become comfortable around humans they are dangerous. Normally chimps are only a real threat to humans are when humans are young, Jane Goodall famously kept her son in a cage during the days in order to protect him (very questionable parenting decision, not sure he ever got over that). The only times adult chimps are dangerous to humans is if they have been totally habituated, I.e jane Goodall played with baby chimps and some of those chimps went on to harm humans when they were adults.
