October 11 [Day 22] [Day 22] (Doug Pedersen) Temperatures were somewhat cooler rising to 10C at 1400 from a low of 0C and remaining at 6C at the end of the day. Ground winds were light SW all day and ridge winds were moderate WSW to SW with strong gusts after 1600 that exceeded 100 km/h after 1800. Patchy valley fog to 1000 affected visibility, then 70-90% stratocumulus diminished to 50% altostratus at noon, to 30% cirrus and cirrostratus at 1500 and 5% cirrus by the end of the day. A total of 198 migrant raptors of 5 species were counted between 0805 and 1856 of which 191 were Golden Eagles (116a, 9sa, 18j, 46u). Movement was fairly steady all day with peak movement of 32 Golden Eagles between 1300 and 1400. Much of the movement around mid-day was above the valley, but by late afternoon birds were moving very high above the Fisher Range. Other migrant raptors were 2u Sharp-shinned Hawks, 2 Northern Goshawks (1a, 1u), 1 adult light morph calurus Red-tailed Hawk, 1 light morph Rough-legged Hawk and an unidentified light morph Buteo. Non raptor migrants included 1 Common Loon, an unidentified gull, 60 Grey-crowned Rosy-Finches in two flocks and 73 Bohemian Waxwings. 12.33 hours (247.16) SSHA 2 (52), NOGO 2 (15), RTHA 1 (34), RLHA 1 (8), UB 1 (7), GOEA 191 (1852) TOTAL 196 (2092)
