Feathers. 1935. Boyes Prairie, Prairie Creek State Park, 240 ft., Humboldt Co., Calif. (cont.) Oct. 23. and continued walking south along the route marked for trail construction. Near the headwaters of Brown Creek, I left the ridge and started down into the rough canyon country to the west. There was some elk sign throughout this territory, and indications of the recent activities of a bull, such as: huckleberry bushes torn and broken by antlers, and ground pawed and torn up. Travel down this canyon was extremely difficult, owing to the presence of rock cliffs, heavy undergrowth of huckleberry, salal and sword fern, and an unusually heavy maze of fallen timber. I emerged on the highway 4 mile north of culvert No. 417+00, at about 5:50 P.M. As I walked south along the highway, I saw a bat fly overhead. I was unable to determine its identity, but noticed the time was 6:10 P.M. It was very cold. I could not find a thermometer when I returned to camp, but the mornings have been frosty for the past two days. Birds and mammals were: varied thrush s, winter wren s, chickadee s, chickaree s. Weather - clear.
