a bobble head turkey decoy is a turkey decoy that is made to look like a feeding turkey with a movable head and neck that moves up down and sideways as the wind blows, works great on turkeys, sometimes when there is a gentle breeze it really looks lifelike, and to me, at a distance kind of looks like a big red tail hawk tearing into a rabbit. they also are now marketing a mojo (whirling wing) hawk decoy. You can buy the turkey decoy for about $19.
I thought of it because I was a falconer and flew redtails at rabbits. It was great fun, except when hawk caught a rabbit, they really screamed, it was awfull. Preditors know too.
We used to joke that we would wish that on one of our reincarnated enemies, to be a rabbit with a hawk on it slow dying in the snow. They just stand on screeming rabbit for a long time with that vise grip. Gruesome.
