I walked around Centennial Lake in the afternoon (1-9-05) with slightly different results from Joe's:

Canada Goose  225
Mallard  10
Canvasback  4
Common Merganser  6
Pied-billed Grebe  1
Great Blue Heron  1
Coot  1
Ring-billed Gull  6
Common Grackle  80,000 estimated, leaving a staging area in the woods to the W and NW, flying across the lake to the E or SE.  This was 4-4:30PM.
