Figure 1.

Average interactions per hour initiated toward each type of human. The figure shows the average number of interactions per hour initiated by each elephant toward three specific categories of humans: tourists, volunteers, and guides. This graph adjusts for the amount of time each individual elephant was visible in the focal group. Individual elephants differed significantly in the overall number of behaviors exhibited toward any human (p < 0.0001). Guide total was significantly greater than volunteer or tourist total (p < 0.0001 in both cases), volunteer and tourist totals did not differ significantly (p = 0.997).
