From a distance, I figured this was a flock of turkeys in an Ohio hayfield outside Mount Vernon last Saturday.
Nope. Vultures. Since I could not see any red on their heads, and because of their apparent sociable habit, they might have been Black Vultures. Or Maybe Turkey Vultures assembling around a corpse. Did not have my binoculars.
Not sure whether Black Vultures are regular in central Ohio.
