Abstract

The breeding bird community of mature pine forests with highly similar foliage profiles was examined on the regional level using data from two censuses from Poland, three censuses from Central Finland, and three censuses from Finnish Lapland. Several parameters revealed a greater difference between the Lapponian and Central Finnish than the Central Finnish and Polish communities. The diversity index H' did not show a similar decreasing pattern from Poland through Central Finland to Lapland as the land bird diversity of wider areas including the whole spectrum of habitats of a particular region or zoogeographical zone.
