- Аннотация: At present, we have noted 24 species of birds on the territory of Omsk Airport. The Eurasian tree sparrow,house sparrow, carrion crow and the forty dominate in abundance. The most dangerous of this list are 13species: western jackdaw, rook, Buteo, European honey buzzard, montagus harrier, pallid harrier, carrioncrow, the black-headed gull, Caspian gull, grey partridge, carrion crow, rock dove and magpie. Thus, overthe twenty-six-year research period, the total abundance of birds in the territory of the Omsk airport remainedvirtually unchanged. Generally we can say that species richness increased in 4 times, when we compared 1987and 2013. It means that this process has been affected by migration and increased feeding of the territory ofthe Omsk airport for migratory predator birds, whose abundance has increased in the post-Soviet period afterthe abolition of the use of herbicides in agriculture. When we speak about abundance on the territory of OmskAirport, we marked that the maximum total abundance of birds was in autumn 2013, e.g. in the second half ofOctober (296 birds) and in the second half of November (262 birds). This is explained in the first case by asignificant concentration of migratory birds from the north-east of Northern Eurasia on the territory of OmskAirport. In November, the increase in bird abundance is explained by the accumulation of local corvidae andpasserine birds during intra-aerial migrations in the urbanized territory of Omsk, which has an increased feedingcapacity and a protected airport regime.
