Large-scale effect of climate change on breeding parameters of pied flycatchers in Western Europe
Variations in laying date and clutch size of pied flycatchers Ficedula hypoleuca across populations throughout western Europe are examined in relation to climatic fluctuations, measured by the winter North Atlantic Oscillation (NAO) index. Across breeding sites, the winter-NAO index affected laying...
