University of Washington Scientists have shown that crows recognize individual human faces and can distinguish scary faces from neutral faces. The scientists wore dangerous masks and neutral masks and walked around the campus with these on. The dangerous masked scientists got scolded by the crows and the neutral masked scientists got no reaction from the crows. Months following the study, the masks were donned again by the scientists and the crows remembered the individuals with the scary masks on. I did not know crows had this ability to recognize human faces. If a crow scolds me, I need to reconsider that new beauty product.
