Golden Eagles 4

Golden Eagles 4

Starting in late winter, Trish Miller and her team set up camera traps baited with deer carcasses. When an eagle lands and takes the bait, it is netted, blood-tested for lead and mercury, and fitted with a small telemetry unit designed by Miller's husband, Michael Lanzone, before being released. Here Miller and Lanzone measure an eagle's wings with a yardstick.
