I would really love there to be more variation to animal aggression! I'm really new to the game, but just from the get-go it seems really weird that all the predators are SO on sight with you. Black bears are nowhere near as aggressive as brown bears, for example!
It would make a lot of sense for bears to be REALLY AGGRESSIVE in the Spring (just woke up, cranky, hungry), mostly ignore the player unless provoked in the Summer, and get focus heavily on foraging in the Fall. Maybe even a mechanic where the bears try to get into player food storage, if it's not in a cellar or stored properly? I also heavily agree with the berries comment - bears are definitely omnivores, they have a very diverse diet.
This might tie into larger animal overhaul, but I think it would be very cool for wolves and other creatures to have clear "dens," where they sleep and the pups spawn. Their aggression could be toned down towards the player unless they stumbled within range of a den. And again, seasonal variation would be good too - in the winter, wolves tend to be more well fed, so maybe they'd be less aggressive towards the player? Wolves go hungry in the summer, so maybe they could be more willing to take the chance? Since I'm new to this game, I'm not sure if this is a mechanic yet, but - are wolves willing to attack players alone? It would make sense to me for them to only attack a player in a group, too.
