Article summary

The 2006-2007 counts were influenced by the extreme mildness of the winter. The January census counted more than 108,000 waterbirds in Wallonia and Brussels of which 60 % were gulls and terns and 22.4 % native ducks and geese. With respect to January 2006, the results indicate a global decrease (-13.9 %), notably most ducks and geese, including Canada Geese. The number of Great Cormorants decreased as well. We can, however, notice an increase in numbers of Great Crested Grebes, Grey Herons, Great White Egrets, and Little Egrets
