Autumn at Merced National Wildlife Refuge

The graveled road made a slight turn, and the first flock of lesser Sandhill cranes — a gorgeous waterfowl that stands 3 to 5 feet tall and weighs about 6 to 7 pounds — gathered together in a wet, golden field of marsh grasses and plants. The superstars of Merced NWR performed an opera of chortling, honking, and bugling songs in the field. Other waterfowl appeared to be their silent, floating audience.
