Just a random WI deer story. I have a few but here’s one.
I was driving on a two-lane highway and saw a deer up ahead on the side of the road so I started slowing down. The deer saw me, panicked and ran into the brush/woods, then changed direction and ran out and back toward the highway. I kept slowing. It changed direction and ran back toward the woods, changed direction again and ran back toward the highway. By now I was at a full stop and parallel to the deer. It ran head first into the side of my truck, fell down, got up and sort of stumbled back into the woods…
Was there a game fence preventing it from entering the woods maybe? Not sure how you do in WI but here in Sweden highways are always lined with game fences.
The sad thing is when an animal somehow gets over it, under it, however, and is then trapped on the highway side.
This is common, deer are incredibly stupid. For those postulating the existence of a fence, no. They do this when there is no fence, both at night and also in broad daylight when there are no headlights to dazzle them either.
My guess: https://en.wikipedia.org/wiki/Chronic_wasting_disease
And based on the USGS map, it is very common in WI.
During the rut, I've seen muleys here in Montana act absolutely bonkers. I once saw a young but large buck darting in and out of traffic, playing chicken with oncoming 50 mph vehicles, to impress a group of does. He'd run across the road right in front of a car, then pronk around proudly while the does stared at him.
