摘要: This note examines the effects of habitat, landscape, climate and geographical situation on occurrence probability red-backed Shrike at its westernmost range boundary. results from 127 sampling localities distributed east-to-west along 600 km in northern Spain reflect local regional species distribution. habitat patch size (the prefers large patches) summer temperatures avoids warmer sites) are two main environmental correlates In addition, decreased sectors study area. this result could be related to a peninsula effect potentially reinforced by atypical migratory circuit passerine (birds arrive east). conservation prospects peripheral population suggest retreat cold highlands as global warming increases, reduction suitable patches due forest encroachment resulting rural abandonment reduced availability individuals offset extinctions border European range.
