The Golden Eagle is the most powerful avian predator in North America but is facing many new challenges. These challenges are especially serious in the sagebrush-steppe environments of the American West.

Not much was known about the birds of the Bighorn Basin in Wyoming until Dr. Charles Preston began a study in 2009 to determine what the birds were eating. His discoveries are crucial to understanding what the Golden Eagles will need to survive amid the landscape changes sweeping the region.
