Assessment of the autumn population in passerine species in anthropogenic landscapes of northern taiga zone in eastern Fennoscandia
Population sizes of 4 mass passerine species (Luscinia svecica, Emberiza shoeniclus, Phylloscopus trochilus, Prunella modularis) were calculated on the ground of recaptures of ringed individuals in a village landscape (ca 1 km 2 ) near Karel’sky Shore of the White Sea in August–September. At migration peak population sizes of all of these species make up hundreds of birds per 1 km 2, which are 1–2 digits higher than those in taiga biotopes in autumn and than breeding population.
