I saw that a couple of days ago. Who knows why turkeys do anything? They're dumber than cows and a lot less tasty.
Alvin York claimed that the habit of turkeys following each other single file was the thing that gave him the advantage in his Great German Turkey Shoot on the Western Front in WWI. He'd shoot the one in the rear coming down the trenches then the next one up the line. With all the noise the Germans couldn't figure out where the shooting was coming from. Alvin kept plugging them until they gave up.
I once came up on three young turkey hens sitting on a log while squirrel hunting in early November. As the season wasn't open, I wasn't interested in them, figuring they would scatter when they spotted me coming down the ridge. I kept getting closer, they didn't move. I can't figure out what's up. When I get about 7 yards away I notice those turkeys are rocking back and forth on the log. There was big bunch of wild grapes growing in the trees above them. Those turkeys were lit on the ferment grapes. I can tell you with God, or anyone else as my witness, those turkeys couldn't fly. They barely hopped off the log when I kicked it.
Crows and ravens hold a grudge. They live a long time, are incredibly intelligent, and have form of communication that lets them clue their offspring into the specific individual humans and animals in their range that are danger to the flock. They'll remember you for decades, something I've actually experienced after a misspent youth of being a groundhog bounty hunter and crow killer.
The last time I was on the old farm where did most of my crow patrol, there was a crow sitting in the top of a dead poplar overlooking the cornfield where I done much of my damage decades before. All I had was a bucket, I was heading down the hill to pick blackberries for my Mom, as she loved the things.
I was barely through the fence and turning down the hill. That old crow in the tree let out that same warning "caw" I'd last heard at fourteen in the same field. That cornfield exploded with crows beating to the pines on the ridge. My guess is that caw meant, "Beat it! It's that murderous kid grown up and these days he doesn't need a gun."
