Results of bird surveys in the North-Western Azov region in 1988-2000

Study Extent

Research was carried out during regular field expeditions of employees of the Azov-Black Sea Ornithological Station to the wetlands of the North-Western Azov region in all seasons of the year in the North-Western Azov region within Zaporizhzhia and Kherson administrative regions of Ukraine.

Sampling

Bird counts were carried out using 10-12x binoculars on walking or driving routes along the shores of the studied water bodies. Birds were counted from vantage points that were selected to include all birds in the wetland and avoid duplication of data. All birds were counted regardless of whether they were on the reservoir or adjacent land. In some cases, a 30x optical tube was used. During the nesting period, nests and broods were also taken into account. On the Molochnyi Estuary, if necessary, surveys from boats were also used. During the surveys, all birds were assigned to a specific control area of arbitrary shape, the boundaries of which were determined by natural landmarks. The coordinates for bird registration are the coordinates of the center of such a site, which were determined using the QGIS program. The accuracy of coordinate estimation was determined as the maximum distance from the center to the boundary of the site.
