I have seen coyotes many times ignore adult turkeys. I have pictures and video of this. In all instances the turkeys never flew and the the coyote barley acknowledged the fact that the turkeys were even there and this was only 30 to 40 yards away. Not to say that a coyote won't kill an adult turkey. Lets face the facts, you all know how keen a turkeys eyesite is, not to mention turkeys can fly and coyotes can't. Coyotes are always hungry so this bird would have been about cleaned up (excepet for feathers and legs) and coyotes LOVE the guts. Its not often coyotes kill adult turkeys
