It began when a runner duck was noted missing...then I found her head. Nothing else. The nest containing the eggs, all intact, that she had been brooding, was nearby. Couple weeks later and we realize 4 eggs have disappeared from a well hidden nest in the oregano patch. Then 2 from another nest. What predator can carry off a duck carcass and jump with it over a high boundary? Our property is pretty securely walled and fenced though trees overhang. Is this decapitation a hall mark of a particular critter? Am planning to set a trap of some kind but need to know what I’m dealing with.
