B. F. Skinner's Dippy Bird

Origins
Skinner was a psychologist who believed that free will was not real, but an illusion. He did research and wrote on the idea of reinforcement. Actions that ended badly were not repeated, while good ones were reinforced.

During WWII, B. F. Skinner tried to train pigeons to operate bombs. The pigeon would be inserted into a missile with a lens in it. The bird would peck at the target through a screen, thereby guiding the missile. The program was eventually cancelled. This artifact came about as the result of his training and possibly his reinforcement psychology.

Effects
Makes pigeons line dance in time with the birds bobbing. Agents are unsure if it works on other birds or only pigeons.
