Features of bird distribution over the forest-field ecotones of southern taiga and northern forest-steppe of the Urals are considered. An increase in species diversity and in the number of birds in the field belts near the forest borders is demonstrated, along with avoidance of forest vicinity by the species living in an open space. Ecological and behavioral aspects of these phenomena are considered. A quantitative estimation of the manifestation of the forest border effect and its role in the formation of the spatial structure of bird population of an agricultural landscape is presented.
