If I could go on a tangent... Wolf, have you ever known these birds to become fascinated with odd objects as playthings? A few years ago, we had a troupe of five that took up residence here around our building/parking lot. Simultaneously, a seemingly random, but daily occurrence of vandalism began happening to our vehicles. It was finally discovered, one, and just one of the crows had a thing for the rubber wiper-blades on our vehicles. He/She would perch on the hood, and yank each end of each windshield wiper until the bead was pulled off. Often they'd be left on the hood, or dangling. Sometimes ten cars a day were hit. Sometimes several days in a row. It took a long time, and finally some sharp eyes on surveillance cameras to figure out it was a BIRD! The only thing we could figure was, it was fun for the Crow... and bonus money for the auto parts stores. Finally, they moved on. I've got a picture somewhere...
