Bearger doesnt spawn

Check that you did not possibly set him to "none" when you  were generating the world as a start point.

He would've/should've spawned in your second Autumn (day 71) unless you were in the caves at the time. Maybe you didn't hear him for some reason & he's in your world in some remote part that you don't frequent. Remember that he does not despawn at the end of Autumn, but just goes into hibernation till the next Autumn & there's no warning sound he makes when coming out off that. This will make you think that he's not spawning every Autumn.

Setting is on default, i really cant find him anyware

I found him.. problem solved 

Too bad i dont have tall birds on my world
