At 5 months old, Yola’s physical strength and self-confidence continues to develop in leaps and bounds, influencing the steps we take to ensure a smooth transition into her gorilla family. We’ve come a long way from the initial visits during Yola’s first months , which consisted of a mostly sleeping infant, to the current youngster in perpetual motion.

Yola’s burgeoning confidence and expanding knowledge of complex gorilla social cues is evident in the way she interacts with her mother and responds to the activities within her group. She watches closely as the gorillas communicate vocally and physically throughout the day. Yola has observed rambunctious play sessions, common displays of dominance and subordination, nest building, foraging and occasional disputes peacefully settled.
