For years, Burmese pythons have invaded Florida's Everglades National Park, preying on indigenous species. Tracking them down has proven time consuming and difficult, so Park wardens have begun testing a new hunting method imported straight from the front lines of the War on Terror: unmanned aerial vehicles (UAVs) and thermal imaging technology.
David Hallac of The National Park Service already uses manned, fixed-wing aircraft to search the Everglades for birds, and he said moving to UAVs to cut down on costs is the natural next step.
