Darlene Taylor was standing on West Main Street in Crisfield the other day and shouted a greeting to a woman she knew coming out of the Crisfield Discount Pharmacy. Seeing Taylor, the woman bolted across the street, to say hello and ask a question. “What’s going on with the pigeons?” she wondered. Taylor is not an ornithologist. Nor is she a hobbyist who keeps homing pigeons on her roof.
