They started with dogs, but trainers shunned the new method, claiming that people had been successfully training for centuries and no new approaches were needed. Rebuffed on the canine front, the Brelands turned to other species. For 47 years, ABE trained animals for its own theme park, the IQ Zoo, in Hot Springs, Ark., as well as for shows across the country. At ABE’s height, the Brelands could have up to 1,000 animals in training at any given time, many for companies such as General Mills, who used them in commercials and at sales conferences. They also worked on animal behavior and training projects for the U.S. Navy and Purina, as well as for Marineland of Florida and Parrot Jungle, where they developed the first of the now-traditional dolphin and parrot shows. When they started, there was only one trained dolphin, whom it had taken trainers two years to get ready to perform. In six weeks, Keller trained two new dolphins to perform the same behaviors.
Bob Bailey met the Brelands when he was hired as director of dolphin training for the navy and Keller and Marian were contracted to help. “I spent six months at ABE learning to train many animals, including chickens.”
Three years later, the same year Keller passed away, Bailey joined ABE as assistant technical director and head of government programs. Later, he became research director too and then executive vice president and general manager. Eventually, he and Marian married.
Over the course of their career, the Baileys trained more than 140 species (or about 16,000 individual animals). In 1990, they retired and closed ABE. Then, in 1996, they received a series of calls from Simon Prins.
Inspired by Dolphins
“I’d spent a year traveling internationally and searching for training methods. I saw a dolphin show, and the girls were training the dolphins to perform incredible behaviors without shock collars or punishment devices. I did more research, and it all led back to Marian and Bob Bailey, so I contacted them,” Prins recalls. It took 20 emails and 10 phone calls before the couple agreed to help. “Bob was quite rude … he hung up on me many times.”
“We didn’t want to deal with police or military because in our experience, they are punishment-based,” says Bob. In the U.S., the Baileys had come to feel that force-based trainers could not make the change to operant technology because eventually, they fell back on the method with which they were most comfortable. “These trainers take what we say and modify it. They take good operant-conditioning principles and modify them, and then say they won’t work.”
Eventually, as Prins continued to meet Bob’s increasing demands, Bob agreed to help. Prins came with a few other trainers as well as his superiors to the Baileys’ Hot Springs headquarters to learn by training chickens.
Animal Behavior Enterprises had tested many animals for learning purposes and found that chickens provide by far the best training model (find out why). Prins and his bosses quickly learned that training is a technical skill rather than a mystical, inborn ability. A science, not a craft. They trained chickens to selectively peck just one type of object among a group of objects, and to perform tasks only on cue. They learned to train behaviors as a series of many little shaping steps, and to keep track of the outcome of each trial in order to determine whether they were having success or needed to fix their technique or plan. They did this all with positive reinforcement — without physically manipulating the chickens.
“Bob and Marian changed my whole perspective on animal training,” says Prins. As a result, he met all of the 1996 goals, and more. At first it was difficult. ABE had developed remote-guidance systems for cats, dogs and dolphins by 1967. In months, they could train dolphins to perform many behaviors, including traveling 12 hours on a circuitous eight-mile route with no reinforcement. It took Prins three years to work out the methods.
