We went looking for the two previously reported loons today, hoping for some semblance of breeding plumage in either. We did find the Yellow-billed, still in winter plumage, and never saw the Red-throated. Also had one winter-plumage Eared Grebe, and a pair of Horned Grebes, one winter, one breeding plumage. There were 5 male Red-breasted Merganser, and one pair of Common Merganser.
Also had scads of Mountain Bluebirds, some Redheads and Ring-necked ducks, Bufflehead, Western Meadowlarks, Killdeer, Shovelers, very distant gulls including some dark-backed, presumably Lesser Black-backed, some Cormorants and Herons building a nesting colony.
