EDIA – Global Bird Monitoring Program of the Alqueva Dam (EFMA) Secondary Irrigation Network, Irrigation Block Alvito-Pisão and Cuba IBA: Large steppe species: Great and Little Bustard and Eurasian Stone Curlew [2016-2022]

The dataset contains records of the large steppe birds - Great bustard (Otis tarda), Little Bustard (Tetrax tetrax) and Eurasian Stone Curlew (Burhinus oedicnemus) collected in the Secondary Irrigation Network of the Alqueva Dam (Block A: Alvito-Pisão) and in the Important Bird Area (IBA) of Cuba, in the framework of a “Bird Atlas” performed within the General Bird Monitoring Plan of the area, promoted by EDIA. Data were collected in the springs and winters of 2016-2018.

An ad-hoc number of road transects was performed to detect the target species (in the surrounding fields) using the 500 km road net of the study area. A total of 684 contacts was obtained, all from the Great Bustard.
