The conditioning of dolphins to human‐interaction behaviors has been documented in several areas worldwide. However, the metrics used to report human‐interaction behaviors vary among studies, making comparison across study areas difficult. The purpose of this study was to develop standard metrics for reporting human‐interaction behaviors and utilize these metrics to quantify the prevalence of human‐interaction behaviors by common bottlenose dolphins ( Tursiops truncatus ) near Savannah, Georgia. The four metrics used were percentage of days with human‐interaction behaviors, percentage of sightings with human‐interaction behaviors, percentage of the catalog that interacted with humans, and spatial extent of human‐interaction behaviors. Human‐interaction behaviors were observed on 69.6% of days and 23.5% of sightings near Savannah. In addition, 20.1% of the animals in the catalog were observed interacting with humans. These rates are much higher than those found in other areas with known issues with human‐interaction behaviors. These behaviors were observed across an area of 272.6 km 2 , which is larger than other reported areas. The four metrics used in this study proved to be a valuable way to report human‐interaction behaviors, and their use is recommended for future studies to allow for comparison among areas.
