LINUM, GERMANY - OCTOBER 04:  Cranes returning from a day's feeding on local farmland fly past a setting sun on October 4, 2010 near Linum, Germany. The marshland near Linum becomes host to up to 80,000 cranes every year on their migratory route from Scandinavia to southern France and Spain. The cranes spend four to six weeks feeding on local, cultivated fields and sleeping in the nearby wetlands before continuing their journey south.  (Photo by Sean Gallup/Getty Images)
