The dataset contains records of Common Kingfisher (Alcedo atthis) and Dipper (Cinclus cinclus) (Aves) collected in the lower catchment 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 August 2010 to September 2014. Sampling was performed in transects distributed along the lower Sabor river valley (and some tributaries) and in rivers Maçãs and Angueira, from the Sabor mouth up to 42 km upstream. The presence and identity of bird species were assessed by visual and/or acoustic observation, with binoculars. The records include taxa identified at the species level.
