All,
The was a female/immature plumaged White-winged Scoter on Baseline Reservoir at 1:30pm this afternoon. It was east of where I parked on south Cherryvale Road, which is just southeast of Boulder.
At the Valmont overlook I ran into Christian Nunes, who had seen a juvenile Pacific Loon on Six Mile Res, which is immediately south of Boulder Res. On Boulder Res he saw a Greater Scaup and a first-year male Barrow's Goldeneye. All these birds escaped my gaze when I arrived there later. Also, no white Geese at Dodd Res.
Cheers, Peter Gent.
