" The crow had something in its mouth. It perched on the edge of the blanket, giving Maggie Rose one of those twisting-head looks that it must have learned from Casey. “Did you bring that for me?” my girl asked. Maggie Rose very carefully and slowly reached into her basket and brought out one of Casey’s peanuts. “That’s a metal washer. My dad has some in the garage. I’m sure he’d like another one. Would you like a reward for bringing it to me?” The crow dropped the metal thing from its mouth and bounced forward a few hops and very cautiously removed the peanut from Maggie Rose’s fingers. I followed the crow’s flight as it rose up into the trees and realized that all of its crow friends were up there watching this whole thing. “It’s a murder of crows, Lily,” Maggie Rose breathed. “And look how many of them are carrying something in their beaks!
