We may never listen to NPR Morning Edition again. In a recent installment of “Brain Candy,” we learned that crows can not only recognize human facial characteristics, they can hold a serious grudge. University of Washington researcher John Marzluff ran an experiment asking various people — bald, hairy, young, old, attractive — to take a stroll while wearing the same caveman mask he had previously worn to bother the cranky birds. Even when participants wore the mask upside down, crows screamed, squawked, and scolded en masse at the wearers. Surprisingly, a Dick Cheney mask attracted little attention, except from the students on campus.
Listen to all the gory details here (we’re convinced this is why producers recently scrapped plans for The Birds remake — too much for audiences) and be very, very scared.
