Geese and swans census results in the Danube region of Ukraine (2011-2019)

Study Extent

The dataset includes census results of 5 species of Anatidae species on the territory of the Ukrainian Danube region during the period of migration and wintering in 2011-2019.

Sampling

The data was collected during route records of birds during migration and wintering. The territory was surveyed by car. During the survey of the territory, all birds of the target species on the route were recorded. Birds were identified using 10x binoculars and a telescope (20-60 X). If possible, the birds were photographed using an SLR camera and a telephoto lens (70-300 and 100-500 mm). Control counting of individuals in the flock and control identification of species in the flock was carried out based on photographs. A drone was also sometimes used to count the number of birds. The results were recorded in the field diary, and later in the database. In most cases, a GPS navigator or a mobile phone with a GPS receiver was used to obtain geographic coordinates. Part of the coordinates was restored with the help of Google Earth based on the entries in the field diary.

Quality Control

The collection of scientific material and its processing was carried out by qualified ornithologists who worked in the region for a long time.
