You missed my favorite one. B.F. Skinner had a WWII weapons program that trained pigeons for use as the guidance system of bombs ( http://en.wikipedia.org/wiki/Project_Pigeon http://en.wikipedia.org/wiki/Project_Pigeon ). From a video I saw (but now cannot find) the pigeons were trained to peck at the shape of a warship. Then they would peck at video of a ship which worked to keep the bomb centered on the warship as it fell by directing the fins to where the pigeon pecked.
