What is a gorilla thinking?
Could end this in a second. Has decided, once again, not to.
A silverback is several times stronger than a person and almost never uses it. Gorilla conflict is overwhelmingly display - chest-beating, charging that stops short, tearing up vegetation - because an actual fight risks injury on both sides.
The chest-beat carries information. The sound is lower in bigger males, so other gorillas can judge size from the beat alone and settle the matter without anyone testing it.
