Article summary

The 2007-8 counts once again were influenced by the mildness of the winter. During the January census, 99,411 water birds were counted in Brussels and the Walloon Region, of which 53.7% were gulls and 27.9% indigenous ducks. Many species over-wintered in only small or medium numbers, such as Great Crested Grebes, Herons, Goosanders, and gulls. On the other hand, high numbers of some birds were recorded: Great White Egrets, Mallards, Goldeneyes, Canada Geese, and Egyptian Geese, with the latter still expanding its range. The Great Cormorant continued to decrease in numbers.
