EDP Foz-Tua: Black Wheatear (Oenanthe leucura) (transects) - Ecological Monitoring Program [2011-12]

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 24 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Temporal Coverage

Project Data

The dataset contains records of the Black Wheatear (Oenanthe leucura, Aves) and other terrestrial birds collected in an area with suitable habitat for the species in the lower Tua valley and included in the Ecological Monitoring Program (2011-12) of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in the winter of 2011 and in the spring of 2012, during field visits to seven transects distributed in the sampling area. All observations were made with binoculars and/or telescopes

Sampling Methods

Sampling was designed to cover the main known or potential habitats for the Black Wheatear along the lower Tua valley affected by the Foz-Tua dam (the mouth) and upstream. A total of seven line transects was established in the selected area, covering the most important habitats for the species (vineyards and traditional olive-orchards). All transects were sampled once in the winter and 1-2 times in the reproductive period (spring), in the early morning or late afternoon. Each transect was walked on foot at a constant speed of 1-2 km/h and lasted no less than 30 minutes. Playback songs were used to locate the territorial (and vagrant) birds. Species identification and assessment of age and sex (when possible) were made “in loco”.
