Adam Kohler, a Wildlife Biologist with the United States Department of Agriculture Wildlife Services at Altus Air Force Base, Okla., handles a recently caught predatory bird Altus AFB. When a raptor is within a close enough range of the airfield to become a hazard, Kohler will set out harmless, simple traps near the bird in order to capture it. Once the raptor is caught, Kohler will place a tracking band on the foot of the bird and relocate it to a safer environment. (Courtesy photo by Adam Kohler)
