I went back to Green Pond and found the four Pectoral Sandpipers continuing in the main flooded field along with 2 Killdeer. Other notables there included 33 Snow Geese, 52 Canada Geese, 2 American Black Ducks, and 3 Eastern Bluebirds.
Two Killdeer and a Great Blue Heron were present at the Newburg Road retention pond, and two more Killdeer and 2 Green-winged Teal were at the Hollo Road retention pond.
I happened to notice three dark birds in the Northwood Avenue 'west' retention pond, so I stopped and they turned out to be 3 Hooded Mergansers.
