September 24 [Day 5] (Cliff Hansen) The temperature ranged from 5C to 12C, ground winds were SW-W up to 20 km/h, but ridge winds were strong SW all day causing most high-flying migrants to be buffeted. Cloud cover was 20-100% mainly altocumulus, initially to the west and subsequently developing into a Chinook Arch. A total of 33 migrant raptors moved between 1006 and 1925 comprising 1 adult Sharp-shinned Hawk, 1 adult light calurus Red-tailed Hawk, and 31 Golden Eagles (6a, 1sa, 5j, 19u) the aging of which was challenged by the height of the flight and lighting that produced mainly silhouettes. The maximum movement was 8 Golden Eagles between 1400 and 1500. Songbird movement was mainly American Robins with 30 birds flying south in two flocks, and a Blue Jay was the first for the season. 11.67 hours (48.59) SSHA 1 (10), RTHA 1 (6), GOEA 31 (123) TOTAL 33 (149)
