The local crows screamed, dove, and followed anyone wearing a mask of Scott.Two days later, John left the Cheney mask in the lab and morphed once again into the caveman. He stepped outside his office building at 11:07, eager to learn whether the crows would remember the face of the man who had captured them earlier in the week. At 11:15, he found a crow near the student union building and began to approach. Immediately the bird flew into a tree and gave a series of harsh calls, flicked its tail, and stared directly down at him. This scolding behavior, identical to how these rowdy birds typically address their natural predators, quickly attracted a second bird. The pair now cautiously eyed John and issued a real tongue lashing. The first scolding bird was unbanded—John had never even handled this aggressive beast. But the second bird wore bands, signaling that it had personally met the caveman a few days earlier. This bird had good reason to scold—the caveman was a proven threat. But the first bird could have known only secondhand about the dangerous caveman. Perhaps she had seen us catch and band her colleague. John continued his walk and in total encountered thirty-one crows, three of whom scolded him.
