School playgrounds offer ample opportunity to observe the unstructured free-play of school-aged children; however, obtaining valid observations can be difficult to accomplish. Recent technological advances in commercially available aerial drones have the potential to contribute to behavior observation work conducted on playground settings. This study compared video recordings from an aerial drone and a tripod-mounted video camera. Behavior observations coded from the videos showed practical equivalence when analyzed using a Bayesian statistic. Results of the study are discussed and practical ethical issues are considered for future research using aerial drones to observe behavior.
