EDP Baixo Sabor: Construction and Reservoir Filling Phases – Kingfisher (Alcedo atthis and Dipper (Cinclus cinclus) - [2010-2014]

Study Extent

The data were collected in a single transect near the river in each 1x1 km square, along the valley of the lower Sabor river, some of its tributaries, and in rivers Maçãs and Angueira, fom the river mouth up to 42 km upstream, in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro e Macedo de Cavaleiros.

Sampling

Sampling was designed to cover the whole valley of the lower Sabor river, its tributaries and rivers Maçãs and Angueira, in habitats suitable for the Kingfisher and the Dipper (riparian galleries, stream pools). A total of 66 transects distributed in a grid of 1x1 km squares was set. Each transect of around 100 meters, was walked by one observer during 10 minutes. All birds detected by sight or sound, as well as nest sites observed or potential, were recorded. The identification was made "in loco" by experienced observers, with the support of appropriate field guides.

Quality Control

All individual identifications were performed by qualified technicians
