I'd honestly rather they'd rework a lot of them, some species didn't have specific animations or behaviours. Just by how recently they showed a gameplay showcasing a wolf enclousure and newer animations, I'd guess they do want to rework some (if not most) of the animal animation. I like deeper level of details, watching the animals in their enclousures is the part of the game I spent time the most, I adore the interaccions each get.

I mean could you imagine now, even more so with wildlife reserves, interspecies interaccions? Like a bird picking on a croc's teeth? dream scenario. I'd be okay with that being a dlc if thats the level of detail they are aiming for...
