Advice from a Congolese park ranger in a Christian Science Monitor article:
Don’t eat or drink in front of gorillas.
Don’t point at them with your finger.
Don’t use a camera flash.
Don’t touch.
Don’t run if a silverback charges. Instead, scooch down and follow your guide’s lead.
Don’t go to the bathroom facing a gorilla; always turn away.
Don’t look a gorilla in the eye.
