The dataset contains breeding-season bird occurrence records collected across the south-eastern steppe zone of Ukraine from 1987 to 2017. It supports analyses of long-term community dynamics and functional diversity across major open-habitat types and landscape contexts.\n\nGeographic and habitat coverage. Northwestern Azov Sea region and adjacent steppe landscapes. Habitat types include continental steppes, steppe meadows, reed beds, continental salt marshes/steppes, and agricultural lands. Spatial information is provided as WGS84 decimal latitude and longitude.\n\nTemporal coverage. 1987–2017; visits during the nesting period (approximately 20 April–20 June), typically 06:00–10:00 in fair weather, with at least two surveys per season per transect.\n\nSampling methodology. Line-transect counts without fixed strip width. Birds were recorded visually and by sound; fly-overs were excluded unless feeding over transects. Each transect was placed within a homogeneous habitat patch. Where needed for density estimation, detections were analysed with the Distance framework.\n\nTaxonomic scope. Class Aves; more than 80 breeding species of open and wetland habitats. Scientific names follow the GBIF Backbone taxonomy; higher ranks (kingdom to genus) are supplied for interoperability.\n\nData records. Darwin Core Occurrence table including at minimum: occurrenceID, eventDate, scientificName, decimalLatitude, decimalLongitude, basisOfRecord = HumanObservation, occurrenceStatus = present; where available, organismQuantity and organismQuantityType, and site or locality.\n\nQuality control. Field forms were digitised and georeferenced in GIS; taxon names were validated against the GBIF Backbone; coordinates were range-checked (−90…90; −180…180). Climate covariates used in associated analyses are not required to reuse the occurrence data.\n\nIntended use. Time-series assessments of avifaunal change, habitat-area effects, and functional-diversity applications in steppe and wetland systems. Please cite the dataset when used.\n        ","language":"eng","homepage":"https://mdpu.org.ua/en/bogdan-khmelnitsky-melitopol-state-pedagogical-university/","citation":{"text":"Koshelev O, Zymaroieva A, Tutova H, Zhukov O (2025).
