About an hour ago [i.e., about 11:30 am], I stopped to check some open water at the outlet of Pike Lake, which is located on the south side of U.S. 12 about 1 mile east of Dayton Lake in southern Berrien County [Michigan].The Early Spring 2008 (Volume 12, No. 1) issue of The Berrien Bird Observer, the newsletter of the Berrien Birding Club notes that five Cackling Geese were recorded on the Niles Christmas Bird Count. Niles is located about 5-7 miles east of Pike Lake.
Amongst the numerous resident Canada Geese and Mallards, I found about a half-dozen Wood Ducks, a pair of Northern Shovelers, a pair of American Wigeon, at least one [American] Black Duck, and a Mute Swan.
Of special note was a "Canada-type" goose that appeared no larger than the nearby Mallards. It would behoove someone with a decent spotting scope to check this bird more closely for the possibility of Cackling Goose.
When I check the outflow this afternoon, only the resident Canada Geese, the pair of Northern Shovelers, and the Mute Swan were present. The amount of open water available was much reduced from yesterday.
