Something to say to a man whose presence you don't enjoy is "I will feed your corpse to starlings!" No one wants to be eaten by birds. Something has gone horrible wrong if birds are nourishing their energy-hogging bodies on your skin and muscle.
I knew one person who liked to mix her dead skin, dried blood, and hair with the bird food she gave to whatever birds frequented her yard. She was fond of knowing that the pieces of herself she discarded were borne away by various species of passerine birds. She failed to realize that the songbirds who consumed her materials were the sport of cruel accipiters.
