At CIA, we find inspiration in all kinds of places. From robotic catfish to real-life spy birds, animals and their look-alikes have helped Agency officers perform a variety of critical duties, including eavesdropping, intelligence gathering, security, covert communications, and photo surveillance. During the Cold War ... CIA's Office of Research and Development created a camera so tiny and lightweight that a pigeon could carry it. The camera was strapped to the bird's chest with a little harness, and the bird would be released over a secret area ... that we wanted to know more about. The camera would snap pictures as the bird flew back home to us. During the Vietnam War ... CIA scientists invented what is known as the seismic intruder detection device. It could be strategically placed to monitor movements up to 300 meters away. However, our scientists had to disguise the technology. Since tigers are native to Vietnam ... they provided the ideal cover. The detection device was designed to look like tiger droppings. In the 1970s, CIA's Office of Research and Development created "Insectothopter," the first insect-sized unmanned aerial vehicle (UAV) of its kind! It was disguised as an everyday dragon fly. CIA's Office of Technical Services thought rats would be a great way to conceal things during the Cold War. They treated the rat's carcass with a preservation agent, cut it open, and created a hollow cavity where our officers could hide things like money, notes, or even film. The rat would then be sewn back up, placed at a pre-determined dead drop location, and then left for the asset to retrieve. During testing phases, the rats went missing because stray cats had stolen them.
