說明
The dataset contains information on the results of bird counts conducted at 32 stationary Vantage Points (VP), as well as counts at 9 Point Counts (PC) and birds surveys along 27 car routes from December 2019 to March 2020 (research methods are detailed in the "Sampling" and "methodStep" sections). Data collection took place along the valleys of the Molochna and Malyi Utliuk rivers, as well as on the shores of the Molochna and Utliuk estuaries. Surveys were conducted over 65 days: December 9–22 (14 days), January 12–27 (16 days), February 6–25 (20 days), and March 8–22 (15 days). The dataset includes 7,170 records resulting from quantitative bird counts, encompassing 128 species and 18 taxa identified at the genus level. Field studies were conducted under individual civil law contracts for the development of scientific and technical products titled "Monitoring of the ornithofauna in the area of the proposed Azov Wind Power Plant aimed at assessing potential threats to birds from its operation", commissioned by "ENBITI UKRAINE LTD" (Kyiv) (ТОВ «ЕНБІТІ Україна» (Київ)).

地理涵蓋範圍
The geography of the conducted studies covers Northwestern Azov Sea Subregion – a submeridional strip up to 100 km long along the valley of the Molochna River, including the Molochna and Utliuk Limans (Melitopol district, Zaporizhzhia region). Landscapes: predominantly agricultural fields bordered by shelterbelts, with small river valleys added to the north and the slopes of marine limans valleys with remnants of natural habitats to the south.

計畫資料
With the help of the project two more publishers from Ukraine were registered. This means that despite rocket attacks, close to the front line, lack of light... Lviv, Kharkiv, Odesa and Melitopol continue to work on publication of scientific archives of the West-Ukrainian Ornithological Society and Azov-Black Sea Ornithological Working Group. Both organizations registered with GBIF and our operators have already handed over the first sets data for publication. And this means that more than 10,000 verified records of bird registrations will appear with open access.

取樣方法
The bird surveys were conducted according to the methodology recommended by Scottish Natural Heritage (Recommended Bird Survey Methods, 2017). Most surveys were carried out using point counts at a network of observation points (VP and PC), with coordinates specified in the fields decimalLatitude and decimalLongitude. Absolute bird counts were conducted from a stationary point within a 2000-meter survey radius over a specific time period (indicated in the sampleSizeValue field). At VP sites, species composition and bird numbers were recorded, along with flight data for target species — their altitudes, directions, duration, intensity, and more. At PC sites, species composition and bird numbers along the shores of the Molochnyi and Utlyuk estuaries were surveyed weekly. Route-based surveys were conducted along vehicle routes of varying lengths (from 3 to 11.8 km). Due to the complex configuration of the routes, the centroid, its coordinates, and the spatial uncertainty value for route-based surveys (coordinateUncertaintyInMeters) were determined as follows. In the QGIS environment, two-kilometre buffer polygons were created around the route lines, and centroids of these polygons were generated. The coordinates of these centroids were calculated and recorded in the fields decimalLatitude and decimalLongitude for the respective routes. The coordinateUncertaintyInMeters parameter was determined as the maximum distance from the centroid to the boundary of the buffer polygon, rounded to the nearest hundred metres. All observations across survey types were conducted using binoculars (8-12x magnification) and spotting scopes (30-60x magnification).

| 研究範圍 | Counts were conducted at a network of designated sites in December 2019 and January–March 2020 on a daily basis during the following periods: December 9–22, January 12–27, February 6–25, and March 8–22. Counts at Vantage Points (VP) lasted for 3 hours, while Point Counts (PC) lasted from 5 to 50 minutes. The time of observations at each point varied from day to day to obtain data on bird activity at different times of the day. Car-based surveys were conducted along routes ranging from 3 to 11.8 kilometres in length. |

方法步驟描述:
- Conducting censuses at specified points or along routes, recording the data in field data sheets and on corresponding maps (noting flight directions of target species and locations of large bird aggregations on the maps).
- Transferring collected survey data into electronic spreadsheets.
- Creating a summary table with the survey data.
- Creating route maps in QGIS software, measuring the lengths of the routes, creating two-kilometre buffers around the routes, identifying the centroids of the buffers, and calculating the maximum distances from the centroids to the boundaries of the respective buffers.
- Importing the summary spreadsheet into OpenRefine to identify and correct errors, standardizing species names according to the nomenclature used by GBIF, and converting the data to the DarwinCore standard.
- Importing data into MS Access database and generating events and occurrence tables.
