EDP Foz-Tua: Terrestrial Birds (point counts) Complementary Studies [2010]

Study Extent

The data were collected within a 5-km buffer around the lower Tua River valley (Northeast Portugal), up to 50 km from the mouth in the municipalities of Carrazeda de Ansiães, Vila Flor, Alijó, Murça and Mirandela.

Sampling

Sampling was designed to cover the main habitat types for terrestrial birds in and around the lower River Tua valley affected by the Foz Tua dam. Each sampling point was visited once in spring (April-May of 2010) and a 10-minute census was performed in each point (limited distance method). Birds were counted and recorded up to a fixed distance (50m) and beyond the distance (up to 100m) separately. Species identification and assessment of age and sex (when possible) were made locally, with the help of appropriate field guides.

Quality Control

All identifications were performed by qualified technicians
