This winter we added six adult Golden Eagles (cooler colors) to our telemetry study. Four eagles (warmer colors) captured in previous years have transmitters that are still functioning.

Two adult male eagles outfitted this winter, Petey (green) and Demetrious (blue), stayed in the Missoula and Bitterroot Valleys long after the adult Golden Eagle migration was over.
