Crows in country will wait for a newborn deer to be left alone in a field by their mothers shortly after birth to peck the baby's eyes out so it dies and the crow can eat it later. My neighbor had told me about this happening, and maybe a month later I saw a fawn with its eyes pecked out shortly after it had died. The doe just sat at the edge of the field by it all night. So sad, but really smart of the crows.

Crows have also been known to alert predators like wolves to easy prey so they can pick the remains.

They also do this to lambs, they're smart but evil
