From what I have seen from Prince Edward County to Niagara on the lake, the waterfowl numbers over all appear to be similiar to previous years for most species. However a much clearer picture will come out tonight or over the next few days when all the results of the lake Ontario waterfowl count arrive.
In some local areas waterfowl appear sparse, and in other they are thick. But in the big picture it looks relatively normal except for some dabbling waterfowl that are stacked up in Windermere Basin in Hamilton. Lots of Pintail, wigeon, shovelers and Green-winged Teal there. Also there are 400+ Ruddy ducks there just like last winter. For Photographers the best place to take pictures of several diving ducks is in the Burlington ship canal at fisherman's pier beside the lift bridge. 1000s of ducks there on the 9th (scoters, scaup, canvasback, redheads, etc).
I participated in the lake Ontario waterfowl count at dawn today and the numbers for my area (east Oshawa-Courtice) other than no swans and low dabbling ducks (due to nearshorefeeding areas iced over) the numbers appear to be normal.
results were: 1145 Greater Scaup, 465 Common Goldeneyes, 79 Bufflehead, 2 Mallard, 140 Canada Geese, 157 Long-tailed Duck, 38 Red-breasted Merganser, 31 Common Merganser 25 just a typical daily winter count for this area.
ps Attila there is a Harlequin Duck off rotary Park in Ajax (mouth of Duffins creek)
