Couverture géographique

This dataset contains standardized bird occurrence records collected during long-term monitoring in south-eastern Ukraine (1987–2017), covering breeding, migration and winter seasons. Methods included fixed-route transects, point counts and colony counts. Coordinates are in WGS84 (decimal degrees); spatial extent: W 35.242006; E 36.265864; S 46.41837; N 47.0796. The current release provides ~28,179 records mostly identified to species. Quality control involved taxonomic validation, duplicate detection and coordinate screening. Georeferencing accuracy is 10–100 m for GPS-era data and ~0.5–1 km for legacy records. The dataset is suitable for trend, diversity and distribution analyses, with attention to variable sampling effort.

Méthodes d'échantillonnage

Observations were conducted using line transects of unlimited width. Only birds stationary or active within the habitat were recorded (e.g. foraging above the transect); transit flights were excluded. Both visual and acoustic detections were used. Surveys were carried out in the early morning hours (approx. 06:00–10:00) under favorable weather conditions at a walking speed of 2–4 km/h. Each location was visited at least twice during the season. Field data were originally recorded on printed maps and later digitized.

Description des étapes de la méthode:

1. Field recording: bird observations were recorded on paper topographic maps (scale 1:200,000), with species name, count, and behavioral notes. Digitization: during the 2010s, records were transferred to GIS projects. Each record was assigned WGS84 coordinates, species name, count, year, and data source. Taxonomic standardization: species names were updated according to BirdLife/GBIF Backbone taxonomy and formatted as binomials. Technical validation: duplicate detection, date validation, coordinate range filters, column formatting, and Darwin Core field checks were applied. Darwin Core export: the final occurrence.txt file was generated using the rgbif package and custom R scripts for GBIF IPT ingestion.
