In the meantime, Buzzard took out his ornithopters. These were hollow-boned winged flying drones with clever foamed-metal joints and a hide of individual black plastic "feathers." The three ornithopters could easily pass for actual buzzards at a distance. Provided, that is, that one failed to notice their thin extrudable antennas and their naked, stripped-metal heads, which were binocular video-cams spaced at the width of human eyes.
