Cogswell 1949 Fales sparveria Aug. 19, 22 "Bald Hills", ½ to 2+ mi. NW Schoolhouse Peak, 2200 - 2600 ft. Humboldt Co. Calif. Frequently seen in the ranches (sheep) and over some of the Barry Oak woodland. A group of 8 and one of 5+ individuals, probably a family group seen at one point (see journal for this date). Aug. 24, 25 Coyote Peak, 3600 ft. Humboldt Co. Calif. - 1 ? seen each day, over the Broken-grass "Bald" area on the N. side of the peak and perching in nearby forest edge trees. Aug. 29 Willow Creek, 400 ft. Humboldt Co. Calif. a pair (? + ♂) soared up from weedy field & woodland border, 1½ mi. N. of the town, the ? rising first to a height of 500+ ft. before the ♂ started up. They flapped in series of 10-15 strokes, alternated with periods of soaring — an action much like that often seen in Accipiters. However, I saw the falion shape well, and the rufous tail with black subterminal band identified the ♂ positively. Aug. 30, 31 - 1 seen in same area. Sep. 3/4} 2½ mi. N Willow Creek, 500 ft., Humboldt Co. Calif. I seen at border of mowed hay & standing corn fields — it uses fence posts for foraging perches as well as telephone poles & trees of the woodland border.
