Additional file 3 of The spatial and temporal exploitation of anthropogenic food sources by common ravens (Corvus corax) in the Alps

Additional file 3. Information on the 45 anthropogenic food sources. Broader resource type groupings (refuse, hut, game park) were based on similarities in sites that were verified (Y) and described from the field surveys. Buffers were estimated based on revisitation analysis, at the distance where revisitations no longer increased with increasing radius size or at the maximum of 150 metres (Additional file 4). The number of different individuals (No. Ind) that were recorded at a site across the tracking period is also reported.
