Shrikes in the south of the Entre-Sambre-et-Meuse : study on the recent evolution of the breeding birds and data on habitat and reproduction.
This study took place between 1991 and 1997. In 1990 10 territories at least of Red-backed Shrikes were observed but none of Great Grey Shrikes. The Great Grey Shrikes population looses 50% every ten years, which means that within 30 years the regression reaches 80-90% (see Tabel 1). Important habitat changes are the principal causes, hunting, rough winters (mid-eighties), pesticides and lack of food are others. On the other hand the Red-backed Shrike surprisingly has increased in this area for the last ten years (see Table 5 & 6). This is mainly due to an extension and restoration of favourable habitats : meadows acquisition for new nature reserves and conversion of fields into spruce or broad-leaved trees plantations (afforestations) are some of the favourable factors.
