Turkeys have to be amoungst the dumbest birds out there.
A couple of weeks ago, I encountered a flock of turkeys on a narrow country road. They saw the car and the group went frantically running down the road. On one side was a forrest, on the other side a corn field. They didn’t have the sense to turn off the road. A less patient driver would have mowed them down.
I have also seen turkeys exhibit similar behavior. Any bird that can drown by looking up into rainfall with its mouth open is definitely stupid. I don't know about wild turkeys, but I have heard of 'farmed turkeys' doing this...
I'm surprised that @BadExample isn't in on this!
