Two travel companies that offer gorilla trekking in Rwanda, Select Adventure Safaris and Arc Earth Travel, recently captured a rare sight during a trekking, of a silverback mountain gorilla beating its chest.

“When the rain finally passed, all the gorillas started to come out of their hiding places and the males were trying to keep warm by chest beating. While watching another gorilla, the silverback came marching in from behind us and put on a show that won’t be forgotten in a hurry by our cool, calm, and collected guest who handled the moment perfectly. She then moved out to ensure we kept a safe distance from the gorillas,” the trekking companies said.

They said that, in theory, they always tried to maintain a good distance, but that it did not always work out that way.

“Masks help us minimise any passing of our diseases to them and distance is maintained as best as possible. We are also limited to one hour with the family as this is the point at which the chance of sharing our diseases with them exponentially increases,” the companies concluded.
