Chris covered for me on my day off.
Movement was moderate with a good dabbler flight but a poor diver flight. Dabblers included 119 Green-winged and 32 Blue-winged Teal, 25 Wigeon, 13 Mallard, and 4 Gadwall. Only 60 Red-necked Grebes were counted along with 26 Common Loons, 2 Horned Grebes, and the first migrant Common and Red-breasted Mergansers of the year.
Shorebirds were also relatively slow with 15 Sanderling, 2 Baird's Sandpiper, and 1 Black-bellied and 1 Semipalmated Plover.
A Scarlet Tanager was seen coming in off the lake in the morning.
