Any theories on why the buffalo/cattle blizzard arrangement? During the April, 1973 blizzard we had in Iowa, our cows rode out the storm in a circle, obviously seen the day after. The blizzard the better part of 2 days. All 5 calves were curled up in a ball around the outside of the circle. When we approached the vacant circle, with the exception of the 5 white lumps around the outside, we were certain the calves were dead. All 5 got up and ran, though, as we got close. Perhaps the bison wedge shape diverts the wind from most of their body to help keep them warmer. I've been told turkeys (domesticated) lift their heads during rain to see what's hitting them.....and drown. So much for survival of the fittest.
