Abstract

The aim of this work was to analyse assemblages of wintering birds in three areas of central Europe, that differ in climate: eastern Poland, northern Poland and western Germany in winter in 2003-2009. The severity of winter moderates distinctly from eastern Poland to Germany, so there ought to be more species and larger numbers of birds in Germany. 5445 birds from 73 species were recorded on the 491 transects with a length 500 m. Generalized linear models of the influence of habitat types and localities on the species richness reflected the significant effect of three habitat types and study area location. The species richness was positively affected by the surface area of towns and villages, and negatively by that of grassland areas. The most species were recorded in W Germany, in E Poland, and the fewest in N Poland. While, numbers of birds increased with increasing areas of hedgerows, villages and towns. Most birds wintered in eastern Poland, and reached higher value compared to N Poland; mostly because of large numbers of a few of the most abundant species: yellowhammer, fieldfare, great tit. We can expect that, with warming climate, the wintering areas in central Europe will host increasingly significant bird numbers.
