Article summary

During a winter that was harder than preceding ones, the general abondance of water birds reached particularly high levels, especially in January and February. This was due principaly to the arrival of a series of species in numbers unprecedented in recent decades. The main species were divers like the great crested grebe and the little grebe, cormorants, goosanders, pochards and tufted ducks. Although very small in absolute terms, the presence of other species was higher than usual in Wallonia and in Brussels (whooper swan, wigeon, goldeneye etc.). On the other hand, numbers of mallards and moorhens were again rather low.
