Baixo Sabor: Land Birds - Construction and Reservoir Filling Phases: Maçãs and Angueira river valleys [2010-2014]

The dataset contains records of land birds (Aves) 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 the upper Sabor sub-basin, outside the area of influence of the dams, from February 2010 to September 2014. These points were thus used as controls to assess the impact of the Sabor Dams. Sampling was performed in selected points distributed along the Maçãs and Angueira river valleys. 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 or genus levels.
