Samenvatting

Unmanned aircraft systems or drones are becoming increasingly more popular, as well amongst hobbyists as for scientific research. They provide new ways for artists to creatively express themselves and make certain studies in fields as wildlife ecology much easier to execute. However, the effect of drones on wildlife is barely described in the literature available today. There are multiple disturbing agents of which the effect on wildlife has been researched and published. These disturbing agents differentiate themselves from other with specific disturbing characteristics. There are some studies that researched the effect of drones on different animal groups, but there have been no studies that have researched the effect of drones on predatory bird species. This study aims to compare the effect of the already researched disturbing agents on predatory bird species with the effect of drones, using available literature.
