Winter avifauna habitat types of urban agglomerations: comparison by qualitative and quantitative indicators
Background. The winter avifauna of urban agglomerations is a rather dynamic object of research, whose indicators differ across cities and years of observation. Depending on the species characteristics and the level of anthropogenization, birds in the territory of cities choose different types of hab...

Birds were recorded separately in R1 – up to 25 m and R2 – from 25 to 50 m. The optimal time for counting at one point is 8–10 minutes. The counting area corresponds to a circle with a known radius.

After comparing the winter avifauna of urban agglomerations of the regional (Lviv) and district (Zhydachiv) levels, which differ in the level of environmental transformation, we established certain differences. A total of 48 species of wintering birds have been recorded, of which the Сommon Goldeneye (Bucephala clangula) and the Ural Owl (Strix uralensis) are protected by the Red Data Book of Ukraine.

Background. The winter avifauna of urban agglomerations is a rather dynamic object of research, whose indicators differ across cities and years of observation.
