A long relationship between elephant and its handler improves their cooperation during working tasks

An international team of researchers has studied a timber elephant population in Myanmar and discovered that Asian elephants perform better at a task when they are commanded by a handler they have known for a longer time.


Working animals, such as horses, military, sheep, dogs, or logging and tourism elephants, spend hours each day in close contact with humans and require training to understand commands and fulfill specific tasks. Training can last from several months to years depending on the species, the training methods, and the tasks required. The ability to work in different situations is important for the safety of working animals and humans alike.


The research team consisted of researchers from the University of Turku, Finland, the University Sorbonne Paris Nord, France, the University of Tours, France, and from the Myanma Timber Enterprise, Myanmar. The researchers studied 52 elephants from a semi-captive population of Asian elephants employed in the logging industry by the Myanma Timber Enterprise.


The Doctoral Candidate and the lead author of the study Océane Liehrmann from the Department of Biology at the University of Turku said, we found that when novelty is involved in a working context, the elephant's familiarity with its handler can affect their willingness to co-operate: elephants who had worked with their mahout, or elephant handler, for over a year performed better in a new work task than those elephants who had a shorter relationship with their handler. This difference does not appear when there was no novelty involved.


Previously relationships lasted a lifetime is facing frequent changes of handlers stressful to elephants?


The researchers asked the elephant-mahout dyads to perform two simple tasks. The first task was a control test: the elephant was standing 8 meters away from the mahout and had to join the mahout when he called his elephant. The researchers were evaluating if the elephant was responding to the call of the mahout or not. The second task was similar but this time there was a long white plastic sheet on the ground and the elephant had to cross the sheet to join the mahout. Here the researcher noted if the elephant agreed to walk on the sheet or not. The sheet was chosen because it is a surface the elephants have never walked on before. Therefore, the sheet represented a novelty to them, which is known to induce stress and is commonly used as a fearful stimulus in behavioral studies.


Doctoral Candidate Jennie Crawley, who participated in the study said, The elephant and his mahout (the elephant handler) develop a working relationship that traditionally lasted for a lifetime. However, the mahout profession and culture are threatened nowadays with many mahouts leaving for more profitable and less demanding jobs in city industries.


Working animals usually have daily routines. However, animals' handlers must be able to anticipate their animals' reactions to unusual circumstances (e.g. novelty or scary situations). By gaining an understanding of their behavior and developing strong bonds over time, handler-animal relationships can improve. Today, elephants often face frequent changes of mahouts, and mahouts are younger and lack experience. Therefore, it is important to understand the mechanisms governing the mahout-elephant relationship and to investigate how the frequent mahout changes affect the quality of their interactions.


Timber elephants begin training at the age of five and enter the workforce at eighteen. The researchers found that during the control test, elephants responded to the call of their mahout and joined them easily when they were 18 years or older and had finished their training. However, when the novel surface was added to the task, they observed that older elephants actually tended to be more reluctant to cross the novel surface. This finding corroborates several other studies suggesting a decrease in curiosity with age.


Océane Liehrmann said, further investigation is needed to gain a better understanding of the mechanisms underlying human-animal comprehension. This information should be integrated into management to adjust animal training methods and working habits, reduce stress and conflicts, and ultimately improve working animal's welfare and performance, as well as the security of both handlers and animals.
