Motorways and roads affect foraging movements of diurnal raptors at different spatial scales: General and species-specific responses

Little is known about the reaction of raptors toward roads. Here, we analyze the response of diurnal birds of prey to motorways and mid-size roads during their daily foraging movements. We hypothesize that human tolerant raptors will select main roads and motorways rather than control sites due to the availability of carrion and the potential abundance of live prey in the verges. Besides, we predict that the abundance of foraging raptors will be higher close to roads and we expect a higher abundance of raptors near mid-sized roads, as the disturbance by traffic will be less intensive than in motorways. For species selecting road zones, we further hypothesize a preference for places close to the asphalt because of access to carcasses.
