Four Sandhill Cranes (Grus canadensis) fly in formation over a farmer's field near Othello, Washington. Hundreds of cranes make a brief stop-over in Eastern Washington on their way to summer on the Arctic tundra. The giant birds - they stand as much as four feet tall and have a wingspan of more than six feet - have plumage that often appears rusty because of iron stains from the water in the tundra ponds.
