Birdlife Biodiversity Surveys, Aguada Pichana Este, Añelo, Neuquén, Argentina – 2023 – TotalEnergies E&P Austral B.V.

Study Extent

The survey was developed in three environmental units already detailed in the geographic coverage section.

Sampling

In the three environmental units described, 10 transects were defined, 5 in the QYC area, 4 in the PA area and one in the BA area. The transect of each observation is specified in the column "Location ID" where this information is summarised. e.g: RCZA-MD-4. This code specifies, firstly the site in which the observation was made (RCZA), then the environmental unit within the site (MD) and finally the transect number (4)

Method steps

1. The proposed transects were traversed on foot by two observers, georeferencing the findings and specifying, as far as possible, the life stage of the individuals (juveniles, adults, and sex). Ornithological binoculars, cameras with interchangeable telephoto lenses and semi-reflex were used, and recordings or ‘playbacks’ with songs and vocalizations of the species of interest were executed in each of them.

The surveys were made in areas which are part of Aguada Pichana Este, an operational site of the oil and gas company, Total Austral. The site was studied within three environmental units called: Quebradas y Cañadones (QyC), which means ravines and canyons, Planicie Arbustiva (PA) which means bushy plain and Bajada Aluvial (BA), which means alluvial floodslope.
