Animals have a wide varieties of behaviors, many of which can be difficult to analyze. To make animal behavior research easier, scientists use ethograms – tables of possible behaviors that they can check off as the observation goes on. The ethogram used by zoo employees to study their elephants is discussed, and ways of making use of and presenting that data investigated. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.
