Spanish Researchers use UAS to Study Raptor Nests
A team from Doñana Biological Station (CSIC) has used an Unmanned Aircraft System (UAS) to test whether nest decorations increased nest-site visibility to conspecifics in black kites (Milvus migrans) in Doñana National Park (Southwestern Spain). Avian nests are frequently concealed or camouflaged, but some species, such as the black kite,
