For one of several military
contracts with the U.S. military, ABE developed a training program for
birds that taught them to search for downed pilots. These birds were
trained to search at a minimum distance of one mile and in most cases much
farther. They did not fly away, although it would have been possible for
them to do so. They also worked many hours in conditions that ranged from
fair to stormy. Their training began when they were mere fledglings - ABE
recognized in the 1950s the importance of incorporating the field of
ethology into its work. Therefore, these birds had been imprinted onto
humans at an early age, which might explain their reluctance to fly away
and their dedication to the task.
Trained birds would search the
ocean for downed pilots. The flyers had small wooden rings attached to
their life vests. Upon locating a downed flyer, the bird would return
with the ring, indicating that it had found someone in the water. Much of
this work was conducted in Lake Hamilton at Hot Springs, Arkansas,
although some of the pictures indicate that the project was demonstrated
to the military at San Diego Bay. Some of this work is described in the
American Psychologist article by the Bailey's, "Outside the Skinner Box."
