Tundra prey question

I just recently moved my pack to the tundra and I've noticed that all the prey is critters, and I was just wondering if there is something like a migration season where larger prey appears, or if the pack level threshold for finding small - large prey is higher in a challenging biome?

Yes what type of trails your hunters can pick seem to be based on their stats/levels, and the threshold increase with biome difficulty. :)

It's incredibly difficult to hunt in harder biomes. I'm in the forest and my 650-790 are catching small trails at less than 10% of the time. I'm still on mostly critter trails.

At what level does my main wolf have to be in order to basically Run  around in glacier I have it unlocked but unfortunately I can’t get to it it says that my mouth is it high enough what needs to be higher I mean I’m at a loss here I can’t I can’t get into the last two because it says that my wolf is in higher Up I’m a little confused can somebody help me

@Kacey, your question is kind of muddled, but I assume you mean you can't send scouts into the glacier and the rainforest because their stats aren't good enough? Scouts need 100 Wisdom to scout the Glacier and 100 Strength to scout the Rainforest. 

@HollowWorld7 thank u
