Résumé :	Population trends in shrikes Laniidae have been very negative in most European countries for the last thirty years (Tucker et al., 1994). In Belgium the Red-backed Shrike Lanius collurio and the Great Grey Shrike Lanius excubitor showed dwindling population numbers during the eighties (Baugniet and Lhoest, 1988). Since the end of that decade, the situation of the Red-backed shrike has improved significantly (Van Nieuwenhuyse, and Vandekerkhove, 1989; Van Nieuwenhuyse, 1992; Kowalski, 1999). Recently its populations have reached levels as seen in the early sixties. At the same time, the situation of the Great Grey Shrike remained negative (Rothhaupt and Van Nieuwenhuyse, 1997). In Flanders (Northern Belgium), the negative trend has led nevertheless to the extinction of both species. Indeed, the positive trend in Lanius collurio observed elsewhere is not seen in the current evolution of populations in this region. We review here all recent data and discuss the future of shrikes in Flanders.
