I tried to find him from every angle possible but no such luck. Tricky guy was likely tucked away somewhere I couldn't see. Ngozi and Nneka were in an impossible spot to photograph them. Thanks to the light off the window none of the 20 attempts I had to get a good photo of Nassir worked though he was visible. Didn't look like Sadiki was out in the day room but I know he also gets access to the bedrooms and keepers will be doing anything they can to provide him with additional attention while he adjusts to alone time.
The one thing I dislike about the indoor Gorilla exhibit is that it's pretty hard to get decent shots of them, although the outdoor exhibit poses the same problems.
I've noticed that Sadiki has access to the day room and bedrooms as well. The couple times I've seen him in the day room, there was a Keeper or two attending to him.
