Okay, I could narrate this whole set of pictures, but I know you aren't going to read anything. You're just going to jump ahead to the pictures of the beasts. What you can't tell from the photos is that I was a) not using telephoto most of the time and b) not photographing the gorillas when they were closest to me, that is, right beside me. One even gave me an incredibly gentle push as it ran by me.
North part of Rwanda (where the gorillas are, in a protected park, sadly where Dianne Fossey is buried)
BTW, a sliverback is an older male Mountain gorilla. The adolescents are black backs. This tribe had three silverbacks and a blackback. The only tension was between the beta and gamma silverbacks. There were four or so females and seven juvenilles. This is the alpha silverback being groomed.
Two silverbacks and a blackback.
