At daybreak on the 8th, I drove over to Colusa National Wildlife Refuge to the spot where the duck was most often seen. Unfortunately, the whole area was enshrouded in fog, limiting sight range to only about 75 yards. The duck was nowhere to be found among the Greater White-fronted Geese, Northern Shovelers, Northern Pintails, American Wigeon, Green-winged Teal, and American Coots. A few Black-necked Stilts were present. In the surrounding area, I found Killdeer, Northern 'Red-shafted' Flicker, a Black Phoebe, small flocks of Bushtits and Ruby-crowned Kinglets, Marsh Wren, and a California Towhee. A drive around the 'Auto Tour Route' revealed Pied-billed Grebe, Great Egret, White-faced Ibis, Cinnamon Teal, Gadwall, Redhead, Bufflehead, Red-shouldered Hawk, Virginia Rail, White-crowned and Golden-crowned Sparrow, and Western Meadowlark.
With little hope of the fog lifting, I headed back up I-5 towards Portland, Oregon. I eventually left the fog in the Central Valley region and climbed up into the mountains framed by clear blue skies. The 'Castle Crags' rock formations were interesting.
A Common Raven was present at a Mount Shasta viewpoint along I-5.
Snow-capped Mount Shasta was an impressive sight.
Amazingly, about twenty miles farther north, I found myself back in fog once again.
Eventually, the fog thinned out as I re-entered Oregon, drove most of the way through the state, and got a motel near Tigard, south of Portland.
