The results of synchronous surveys of birds in the wetlands of the Azov-Black Sea region of Ukraine in August 2018

Study Extent

The data is given in total for the entire wetland. The coordinates of the centroid of the wetland or the area of ​​the wetland are indicated as standard coordinates in the dataset table. In the coordinateUncertaintyInMeters field, the largest distance from the center of the plot to its borders is indicated.

Sampling

The basic method was the absolute recording of birds in well-observed areas (sectors) of wetlands and adjacent land. The water areas of small reservoirs were completely surveyed from the shore, large ones - from water transport. All birds associated with these wetlands, including those flying over it, were taken into account. Counting was carried out from an optimal distance that did not allow birds to be alarmed and, at the same time, allowed the observer to accurately determine their species and number. Linear accounting transects were carried out only in solid reed thickets, swampy floodplain forests, floodplain meadows overgrown with shrubs and other areas where a survey of the entire water area or territory was impossible. Observations were carried out with the help of 10-12x binoculars and 30-60x telescopes, photography was carried out whenever possible. Some authors used drones in hard-to-reach places, which is indicated in the samplingProtocol field. In case of an incomplete survey of the entire wetland, the authors of the observations displayed the surveyed territory on the map. Detailed information about methods is on https://www.izan.kiev.ua/rom/methods.htm The coordinates of the plot center were determined in the free software QGIS, version 3.4. Only the numbers and coordinates for large clusters in Central Syvash and Molochnyj Lyman are indicated separately. The nomenclature follows the Catalog of Life.

Quality Control

The authors of the dataset are fully responsible for the quality of the published data.

Method steps

1. Conducting of a field survey within the previousely chosen plot/wetland/land area according to the standard method.
2. Counting of the birds with simultaneous identification of species.
3. Creating maps of the records made.
4. Georeferencing and creating of the lists of registered species and specimens.
5. Organizing of the dataset according to the DarwinCore standards.

The dataset is made of records of birds (class: Aves) inhabiting wetlands in the southern part of Ukraine.

1. Animalia
   rank: kingdom
2. Chordata
   rank: phylum
3. Aves
   rank: class

The dataset covers the area of the Ukrainian part of the coast of Black and Azov Seas: southern districts of Odes'ka, Mykolaivs'ka, Khersons'ka, Zaporiz'ka, Donets'ka regionas (Oblast's) and Autonomous Republic of Crimea, Ukraine.
