Dynamique de population de la Pie-grièche écorcheur (Lanius collurio) dans le sud-est de la Belgique : modélisation de l'influence du climat ; Population dynamics of Red-backed Shrike (Lanius collurio) in south-eastern Belgium: modelling of climate influence

In some areas of Western Europe, Red-backed Shrike populations, following a strong decline in the third quarter of the 20th century, were re-established in recent decades. Variations in climate seem to have played a crucial part in this striking evolution by modulating the species breeding success. In order to test this hypothesis, the annual fluctuations of several of these populations in south-eastern Belgium were compared with the variations in a series of climatic factors. This study derives from a number of censuses, completed during the breeding period between 1979 and 2008, and the data... Mehr ...
