Yesterday was so blustery and windy at Centennial Lake that I almost 
turned back and gave up on the idea of looking for birds.  But I did 
find an intrepid early Phoebe on the north side of the lake about the 
conservation area.  Outside of lots of Canada Geese, waterfowl were 
sparse:  4 buffleheads (2 of each gender), 1 female Canvasback, 5 
ring-necked ducks (1 female), 2 hooded mergansers (both genders).
