I didn't see the new male tiger yesterday, as I only had time for a quick(ish) drive, but it did look like they were mixing the male wolf with one of the girls (Morena, I think). Plenty of researchers and staff on hand watching. The lion drive was also fully closed which I haven't seen happen very often. It's usually open even if they're all inside.
The wildebeest calves looked to be doing well to my untrained eye, and Froja the moose was indeed still in with the bison who are currently moulting everywhere and looking a bit of a mess.
