The dataset contains records of the main avian prey species of Bonelli’s Eagle (Aquila fasciata) and other large birds of prey: Red-legged Partridge (Alectoris rufa), Rock Pigeon (Columba livia) and Wood Pigeon (Columba palumbus) (Aves, Galliformes and Columbiformes), collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of point counts performed each season (winter, spring, summer and autumn), in the known territories of the Bonelli's Eagle in the lower Sabor river valley, from February 2010 to September 2014. Data consists of observations of individuals per sampling point.

The dataset contains records of Iberian Wolf (Canis lupus), Wild Boar (Sus scrofa) and Roe Deer (Capreolus capreolus) collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of surveys made in and around the area affected by the dams, from March 2011 to August 2014. Sampling was performed by camera-traps distributed along the lower Sabor river valley (and some tributaries) and in rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species were assessed by observing the photos taken with the cameras. A total of 3879 photos of the target species were obtained (2892 of Sus scrofa, 982 of Capreolus capreolus, and 5 of Canis lupus). These numbers do not necessarily refer to different individuals.

The dataset contains records of the Roe Deer (Capreolus capreolus), a major wild prey of the Iberian Wolf, collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of surveys made in and around the area affected by the dam, from June 2010 to April 2014. Sampling was performed in transects distributed along the lower Sabor river valley (and some tributaries), and in rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence of the target species was assessed through faecal pellet surveys, due to difficulties in directly observing the species.

The dataset contains records of a key prey species of Bonelli’s Eagle (Aquila fasciata) and other large birds of prey, the Rabbit (Oryctolagus cuniculus) (Mammalia, Lagomorpha), collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of line transects performed each season (winter, spring, summer and autumn), in the known territories of the Bonelli's Eagle in the lower Sabor river valley, from February 2010 to September 2014. Data consists of presence signs (scats, latrines) recorded per transect surveyed.

The dataset contains records of the Wild Boar (Sus scrofa), a main natural prey of the Iberian Wolf collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of surveys made in and around the area affected by the dam, from June 2010 to September 2014.
