advertisement. They trained animals for many other venues including circuses, motion pictures, museums, stores, and zoos. Earlier animal trainers had historically relied primarily on punishment when teaching animals. Bailey and Breland instead followed Skinner's emphasis on the use of positive reinforcement to train animals, using rewards for desired behavior. Although other students of Skinner's later entered commercial animal training as well, the pair's techniques dominated the field because they found ways to simplify the training of complex behaviors. The couple did not just train the animals. They also trained other animal trainers, establishing in 1947 "the first school and instruction manual for teaching animal trainers the applied technology of behavior analysis." Marlin Perkins of Wild Kingdom and Walt Disney were among those who learned from them. Bailey led ABE's government research, some of which remains classified to this day. Known projects included the development of an avian ambush detection system. In 1950, Bailey and Breland relocated ABE to a farm near Hot Springs, Arkansas. In 1955, they opened the "I.Q. Zoo" in Hot Springs as both a training facility and a showcase of trained animals. "Popular acts included chickens that walked tightropes, dispensed souvenirs and fortune cards, danced to music from jukeboxes, played baseball and ran the bases; rabbits that kissed their (plastic) girlfriends, rode fire trucks and sounded sirens, and rolled wheels of fortune; ducks that played pianos and drums; and raccoons that played basketball." Bailey and Breland were also "the first to introduce the public to the applied technology of behavior analysis via numerous personal appearances at fairs, exhibitions, and theme parks across the country". They appeared on well known television shows such as The Today Show, The Tonight Show, Wild Kingdom, and You Asked For It. Publications including Colliers, Life, Popular Mechanics, Reader's Digest, Saturday Evening Post, Time, and even The Wall Street Journal featured them and their work. Although Breland was often the public face of ABE with some ads referring to "Keller Breland's I.Q. Zoo," both of them collaborated equally in ABE's endeavors. The couple stirred controversy among behaviorists with their 1961 article, "The misbehavior of organisms"the title of which involved a play on words referring to Skinner's The Behavior of Organisms. Bailey and Breland outlined training difficulties in which instinct or instinctive drift might occur as tendencies biologically inherent in a species intrude into the behaviors a trainer was attempting to teach an animal.
