Article summary

Population trends of common bird species in Wallonia are computed for the period 1990-2005. Indices are given for 79 species with some basic statistics, tests results for regional or habitats variations and a short comment on quality of observation. The final discussion also tackles the question of data quality and representativeness. The changes observed in a majority of the species arehigh : ± 3 % per year or higher. Sharp decreases are observed in farmland species (Partridge, Turtle-dove, Corn Bunting and, to some extend, Skylark, Meadow Pipit and Yellow Wagtail). Others are increasing : Stonechat, Grasshopper Warbler, Whitethroat. In general, common forest species fare well, but some of them are worrysome : Tree Pipit, Wood Warbler, Golden Oriole, Willow Tit. Some specialized species, like the Common Cuckoo, are strongly decreasing. To date, there is no clear evidence of any effect of global warming. The impoverishment of the avifauna in the Belgian Lorraine, observed for several years, is continuing.
