Cover Story: Drone use has significantly grown in recent years, but there is a knowledge gap regarding how the noise produced by these systems may affect animals. We investigated how 18 species of megafauna reacted to drone sound pressure levels at different frequencies in an ex situ environment. We found that the sound pressure level on the low frequency did not change the studied species’ behavior except for the Asian elephant. All other species showed higher noise sensitivity at medium and high frequencies. Our results suggest that drone sound pressure levels in different frequencies cause behavioral changes that differ among species, which is relevant to assessing drone disturbances. These findings can help to reduce drone impact for target species and serve as an experimental study for future drone use guidelines. View this paper
