November 3 [Day 43] (Cliff Hansen) The temperature at 0830 was 5C which along with 5C at 1300 was the high for the day, the low being 3C for the rest of the morning and at the end of the day. Ground winds were SW 5-10 gusting 15 km/h all day, and ridge winds were moderate to strong SW gusting to 85 km/h at noon, but becoming light by late afternoon. Cloud cover was initially 20% cumulus and altostratus increasing to 90% at noon and the afternoon saw 50-90% cumulus and cirrus that gave good observing conditions despite the western ridges being hazy for much of the day. A total of 16 raptors migrated between 1037 and 1708 with a peak movement of 6 birds (1 Bald and 5 Golden Eagles) between 1600 and 1700, with all birds moving above the Fisher Range. The flight comprised 2 adult Bald Eagles, 1 unaged Sharp-shinned Hawk, 1 small indeterminate Accipiter and 12 Golden Eagles (7a,2j,3u). A few flocks of Canada Geese flew high to the south in late afternoon including a V of 60 at 1825, and finches included 150 Common Redpolls, 110 Pine Siskins and a total of 260 which could have been either or both. Twenty-five students from the Siksika (Blackfoot) Reserve visited the site in the afternoon, that unfortunately coincided with a lull in the day's movement.

10 hours (486.11) BAEA 2 (106), SSHA 1 (112), UA 1 (3), GOEA 12 (3363) TOTAL 16 (3741)


The adventures of “Elaine” (Golden Eagle #78453) Rob Domenech has informed me at Elaine is holding up in the Bob Marshall area just south of Hungry Horse Reservoir, possibly because she is feeding on ungulate gut piles left by hunters. He notes that she stayed in their Nora Ridge/Lincoln study area for about 10 days last fall before again moving south, and he expects her to pick up her southerly track in a week or so and find her way to last year's wintering area south of Livingstone, Montana and north of Yellowstone National Park.
