Résumé :	The bird censuses from October 2005 to March 2006 were influenced by the mild autumn of 2005 followed by fairly cold weather with many ponds freezing by mid-January. The January census counted more than 125.000 water birds in the Walloon region and Brussels, with 58,9% gulls and terns and 25% native ducks and geese. The numbers obtained are on the whole similar to those for January 2005. The results indicate an increasing number of Great White and Little Egrets and Canada Geese (+26,6% in one year), as well as an abundance of Gadwalls and Shovellers. There were large numbers of Little Grebes, Mallards and Tufted Ducks for our region. On the other hand,, some wintering birds were infrequent; the levelling off of the wintering of the Cormorant is now confirmed (-22.3% in January as compared to the maximum in 2003)
