The Advantage Of Opposable Thumbs

Walking through a parking lot to lunch on Monday, I noticed a crow peering intently into a translucent plastic container that had been dropped on the pavement. It occurred to me the crow could see food in the container, but couldn't open it. So, I walked up and unlatched the sealed container. There wasn't much - the chicken bone had been picked clean by some human - but there were a few grains of rice that might make a good crow snack.
