Résumé :	From information available in the literature, it appears that there are few ( 30 birds/windmill/year) and probably has a significant negative impact on certain bird populations, at least at the local level. The indirect effects, arising primarily from the scarecrow effect and from the eventual alteration of habitat, are generally small; they depend essentially on the nature and richness of the sites.Other than specific factors, which lead one to think that certain species are more sensitive, notably ones of large size and slow flight such as raptors, the configuration and position of windmill farms are undoubtedly most important. In this respect, the Walloon situation is reasonably good, with the risks of large scale hits' probably restricted. However, many uncertainties and much imprecision remain, including the rapid technological development that has led to the present use of windmills much larger than those upon which information in the literature is based.This implies that, first, studies of the impact of windmills on bird life (and more generally on all fauna); should continue to be made and, second, that new projects should be very closely evaluated for risks of incidence before any decisions are taken.
