September 23 [Day 4] (Jim Davis) The temperature reached a high of 13C at 1300 from a low of -3C, and it was still 8C at 1945. Ground winds were calm to light to 1015 after which they were SW gusting 40 km/h diminishing somewhat after 1600 and ridge winds were SW moderate to strong all day. It was cloudless to 1100 after which mainly altocumulus cloud gradually developed reaching 100% after 1300. The good migration conditions and excellent viewing conditions produced a season high total of 95 migrant raptors that moved between 0855 (the season’s first Cooper’s Hawk) and 1902 when the day’s 7th Sharp-shinned Hawk went south. The flight comprised 3 Bald Eagles, 1 juvenile Northern Harrier (the season’s first), 7 Sharp-shinned Hawks (all of indeterminate age), 2 Cooper’s Hawks (1a, 1u), I adult Northern Goshawk, 2 adult Red-tailed Hawks (light morph calurus) and a season high 79 Golden Eagles (61a, 3sa, 5j, 10u). The busiest hour was 1000-1100 with 28 migrants moving of which 25 were Golden Eagles. Once again the birds appeared to be moving from Heart Mountain to the Fisher Range bypassing Mount Lorette, and the rate of movement appeared to diminish as the wind velocity increased. Migrant passerines included 8 Orange-crowned Warblers, 20 Yellow-rumped Warblers, 1 Townsend’s Warbler, 1 American Redstart and 10 Barn Swallows. 12.5 hours (36.92) BAEA 3 (5), NOHA 1 (1), SSHA 7 (9), COHA 2 (2), NOGO 1 (1), RTHA 2 (5), GOEA 79 (92) TOTAL 95 (116)
