MSU MAIN BUILDING AS A MODEL OBJECT FOR STUDYING THE ROOFTOP AVIFAUNA

It is proposed to use the 24th floor balcony (135-140 m from the ground) of the Main Building of Moscow State University as a model object for studying the roof avifauna of urban buildings. 5 bird species (~10% of all birds nesting in the vicinity of Moscow State University) were recorded there during their nesting period in 2021-22. These were Columba livia, Motacilla alba, and Phoenicurus ochruros. Falco peregrinus and occasionally Corvus corax nested above the 24th floor balcony. Erithacus rubecula and Motacilla flava periodically and occasionally fly onto the balcony during the warm season, and Parus major does it in winter. Caprimulgus europaeus was seen on the balcony during its autumn migration. Thus, there is a peculiar roof avifauna in multi-storey urban buildings, which is proposed to be included in ground counts of bird species.
