English: “Adult female-infant wild chimpanzees feeding on Ficus sur fruits in Kibale National Park, Uganda. The infant was one-year old, and he was still breast feeding. However, he has been seen to taste the flesh of red (very ripe) fruits. The picture was taken during my postdoctoral fellowship at Harvard University, during which I studied the relationship between contest competition and the nutritional quality of wild fruits. I made the very first detailed study on chimpanzees’ nutritional ecology with descriptions of behaviors never seen before. Most of my observations were collected directly in the canopy with wild chimpanzees all around. Needless to say that this was the project of my life. Picture taken at 25 m above the ground.”
