Spreading, migration, number and biology of shore lark Eremophila alpestris (L., 1758) in the European northeast of Russia

The work is devoted to a usual and numerous species in the European North of Russia - the shore lark Eremophila alpestris (L., 1758). The anthropogenous loading considerably increases in the European North of Russia, number of birds within exploited mineral deposits decreases. On the basis of researches (1965-2013) and the published materials the analysis of condition of the population since mid-XIX century is presented. It is shown that in natural habitats number of the species remains at rather high level.
