My wife and I stopped by around 1 PM to check Pierce Lake. A Common Loon and Bonaparte’s Gull were new for the year. A kayaker flushed all the birds on the lake before I was half through scanning, and I don’t know how many of the birds returned, but there was a good selection of waterfowl. Besides the usual Mallards and Canada Geese (not many of either), there were good numbers of Lesser Scaup, Buffleheads, Ruddy Ducks, Hooded Mergansers, Pied-billed Grebes, lesser numbers of Common Mergansers, Red-breasted Mergansers, Shovelers, Redheads, Ring-necked Ducks, Blue-winged Teal, and a few Greater Scaup, Green-winged Teal, Gadwall, Common Goldeneyes, and American Wigeon. Some Wood Ducks flew over. Missed Black Duck, Pintail, Canvasback. There were a few Herring Gulls with the several dozen Ring-billed Gulls. No swallows. Watched a Cooper’s Hawk in courtship display flight, fluffing out its undertail coverts far to its sides.
