The dataset contains records of riparian bird species (Aves) of high conservation priority, 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 February 2010 to September 2014. Data consists of observations of the target species (the Kingfisher and the Dipper) performed in fixed sampling points or transects directed to riparian birds, as well as additional observations. Observations came from all the study area around the Sabor river, from its mouth up to 42 km upstream. The presence and identity of bird species were assessed by visual and/or acoustic observation, with the support of binoculars. The records include taxa identified at the species level.
