Once I was in a wooded area up by Isanti, MN. A big bird jumped onto a high branch in a tree Cackling all the way. To me it was a dark big bird, I Screamed and as it left the branch I shot. It turn out to be a big old hen. I buried it on the spot. Moral of the story don't go by the cackling. You may get a bigger surprise than I did.---Bob
