                        |  | Due to the mosaic nature of conditions, the diversity of the living environment and the selectivity of certain species to it, a high level of bird biodiversity is noted on the territory of the Altai-Sayan ecoregion (Central Siberian part). For a detailed analysis of the peculiarities of nesting and distribution, we have selected the most common species, the abundance of which is numerous (10–99 individuals / km2), or very numerous (100 or more individuals / km2). Accordingly, we have identified the following representatives: song thrush (Turdus philomelos Brеhm.); red-browed (Turdus iliacus L.); black-throated thrush (Turdus atrogularis Jarocki); olive thrush (Turdus obscurus Gmel.); deer (Turdus viscivorus L.); fieldfare (Turdus pilaris L.); red-throated thrush (Turdus ruficollis R.). Keywords:Altai-Sayan ecoregion, biodiversity of birds, nesting, phenology, distribution, abundance, Blackbirds, Corvids. |  |
