Golden Eagles are only partially migratory. In fact, many western specimens remain close to their breeding areas for life. Much of what appears to be migratory behavior is actually the dispersal of juvenile birds that live a fairly nomadic existence before returning to the vicinity of their birthplaces. The only fully migratory populations are those that breed in Alaska, Western Canada, and parts of northeastern Canada. Northern birds travel to the southern plains where they can hunt for Jackrabbits and ground squirrels during the winter. The greatest population densities occur during winter in the Great Basin and surrounding areas, where resident Golden Eagles mix with migrants from the north.
