Snow Geese - Chen caerulescens - maybe? The identification of these four swimming in the old mill pond on the Maiden Creek at Lenhartsville has me a bit puzzled. The darker two appear to be immature specimens of grey morph Snow Geese. The two white ones, however, could be Snow Geese or Ross's - the distance and the fact they were swimming away fairly fast makes it hard to be certain, but I still lean toward Snow Goose as an identification for them as well.
