Mountain gorilla gesture action example videos

These are example videos of mountain gorilla (Gorilla beringei beringei) gesture actions. Gesture actions observed on at least 3 occasions are considered as part of the mountain gorilla repertoire (n = 63 gesture actions). An additional n = 12 actions (examples with (?) after the name) are included for reference - these were observed on fewer than three occasions and are currently not incorporated into the mountain gorilla gesture action repertoire.
