EDP Foz Tua: Black Wheatear (Oenanthe leucura) (Aves) - Ecological Monitoring Program [2012-2017]

Study Extent

The data were collected within a 5-km buffer around the Tua lower valley (Northeast Portugal), up to 22 km from the mouth, in the municipalities of Alijó, Carrazeda de Ansiães and Murça

Sampling

Sampling was designed to cover the main area of reproduction of the Black Wheatear along the lower Tua River valley affected by the Foz-Tua dam, particularly in the last 7 km of the river, where most couples have their territories.
The area was intensively searched, and all known or potential territories were visited once (winter and summer/autumn) or twice (spring). Singing playbacks (five minutes each) were performed to enhance the response of the birds. Species identification and assessment of age and sex (when possible) were made “in loco”, with the help of appropriate field guides.

Quality Control

All identifications were performed by qualified technicians
