- Title
Long-Term Dynamics of Winter Communities of Forest Birds in the Ilmen Nature Reserve.

- Abstract
Quantitative data of winter bird censuses in forest habitats of the Ilmen Nature Reserve (1986-2010) have been analyzed with regard to changes in the monthly average, maximum, and minimum temperatures and precipitation in the period from December to February. No warming trend has been revealed in the reserve over the study period, The dynamics of bird population structure in winter has proved to be independent of weather conditions, despite significant interannual fluctuations. The most significant factors of long-term dynamics of abundance of wintering birds include population density in the previous nesting period, the seed yield of the main food plants, and local migration of wintering species.
