Abstract
In this article we discuss the seasonal dynamics and population density of Birds of Prey at the Nizhniy Novgorod International airport “Strigino”, based on data collected fro m November, 2013 to November, 2014. During this period a total of 71 raptors of 9 species were observed, including one breeding species – the Eurasian Marsh Harrier ( Circus aeruginosus ) . The seasonal population dynamics and species composition of Birds of Prey on the territory of the airport was studied. The highest population density and species number occurred during end of June – July, in September and in April. The summer population peak was caused by regular observations of hunting birds, whose nests were located on the territory of the airport and in the close vicinity. Young birds also made a contribution to this peak. Autumn and spring population peaks were caused by more frequent observations of migrating raptors during the seasonal migrations. The lowest number of raptors in the airport was observed in winter.
