Density changes and habitat shift of great grey shrike Lanius excubitor during the non-breeding season
Abstract Bird population density and their behaviour during non-breeding periods are determined mainly by meteorological conditions which force birds to use alternative strategies — migration to areas with more advantageous conditions or adaptation to existing conditions. During the 2002/03–2004/5 n...
