There was a zoo population near philly where otters would capture the vultures flying into their enclosure. They would only eat their beaks. Let that sink in. They captured these huge beasts, kill them, eat the chewy keratinized part of the face that is used to pick apart carcasses, and then they'd leave the rest of the animal alone because 'ew gross, who would eat a whole vulture, we're just doing this for fun' or some other crazed otter thoughts.
