It's the same with the three other season themed animals, which is rather cool. I only wish there was more of this, as seasons don't have enough effect on the game in my eyes. Yes, there is the scale and event changes but there should also be changes to supplies (extreme in mountain terrain) etc. Then you REALLY would have to plan your army campaigns carefully, maybe putting them of over winter, waiting for spring and so on.
If season had more impact things like forest, mountain, waste survival would be much more valuable and interesting and summons like these a little bit more valuable.
