Voles scent mark their territories with urine and faeces that are visible in ultraviolet (UV) light. Rough-legged Buzzards Buteo lagopus feed mainly on voles. We performed a field experiment in northern Finland to test whether buzzards are attracted to UV-visible vole scent marks. The buzzards hunted more often on plots with vole scent marks than on control plots. Our results indicate that Rough-legged Buzzards may be able to use vole scent marks as a cue when searching for profitable hunting and breeding areas.
