Day One He watched, and waited, and waited and watched. There were no carcasses in the valley.
Day Two He flew, and soared, watched and waited. But there were no carcasses in the valley.
Day Three He watched, waited, flew, and soared. He imagined he was a military drone, although his big beak and feathers were a dead giveaway that he wasn't. Not a carcass in sight.
Day Four He flew, watched, soared, waited, shuffled, scratched, farted and pondered. Not one carcass - zero, zilch, nada.
Day Five There was a carcass in the valley! Unfortunately it was the vulture's.
