I had the opportunity to spend a day tracking mountain gorillas in the Bwindi Impenetrable Forest in western Uganda. Amazing experience. The gorillas are wild, although the groups that allow humans to approach are acclimated you human presence.

No gorilla fights. However a blackback male gorilla did approach our group (we are supposed to maintain a substantial distance but if the gorillas approach you, you are supposed to freeze and not meet their eyes). He ended up giving a playful shove to one member of our party who went flying into the brush. The gorilla chuffed a laugh and continued on his way. Damn funny video.
