Early this afternoon (Sat., Oct. 29th), I stopped at some selected spots along the west shore of Pyramid Lake. The best bird was an immature Surf Scoter observed at Warrior Point (just south of the point). I had great looks for about 15 minutes before the bird suddenly flew up and north to the point, veered west around the point and disappeared from view. I looked for it along Warrior Point beach and other points north up to the Willows but could not relocate it. Other birds at Warrior Point included about 7 or 8 Greater Scaup. Off shore from the Willows, there were 2 Red-Breasted Mergansers, a Common Loon, and a couple of Greater Scaup. Stopping at the south end of the lake on my way home, I ran into Rose Strickland and Dennis Ghiglieri. Together, birds that we observed there included an American Avocet, an American White Pelican, 40-50 Least Sandpiper, a Bonaparte's Gull, and what looked like some sort of light-headed and dark brown-backed gull feeding on the carcass of a duck in the shallow pools of water at the south end. Once the bird flew up and around, white shafts on the primaries below and above the wing quickly identified the bird as a Parasitic Jaeger. Other features observed included a weakly-barred tail and the dark tip of the slender bill covering no than more a third of the light-bluish bill. Sunset was gorgeous at the end of the day.
