i was picking rhubarb on sunday at my parents' farm, and we heard the most awful noises. it sounded like an animal in the throes of death. we hurried to see - and saw, in the back field, these two sandhill cranes. i think they were killing a snake. they kept flying up about 3 feet, one at a time, and making those noises. i need a better telephoto lens! it was so exciting.
