Article summary

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 & LHOEST, 1988). Since the end of that decade, the situation of the Red-backed shrike has improved significantly (VAN NIEUWENHUYSE, & 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 & VAN NIEUWENHUYSE, 1997).
