October 12 [Day 21] (Cliff Hansen, assisted by Kevin Barker) Temperatures continued to fall to more seasonal norms with a high of 10C at 1600 from a morning low of 4C, and the day's low was 3C at 1900. Ground winds were generally light SW-WSW gusting to 15 km/h between 1200 and 1700, and ridge winds were mainly moderate SW-WSW gusting to 63 km/h in the afternoon. Cloud cover was 60-70% cumulus all day giving good observing conditions, and the western peaks were 30% obscured after 1400 and reached 60% at 1900. The first Golden Eagle appeared at 0849 and two more passed before 0900, then 27 were seen between 0900 and 1000 suggesting another big day was in the offing, but this turned out to be the highest hourly count of the day. The flow of eagles gradually diminished and only 7 birds occurred between 1300 and 1700 before the flow increased slightly at the end of the day with 12 birds passing after 1700. Other raptors were relatively scarce and the final count was 2 Sharp-shinned Hawks (1j,1u), 2 unaged Cooper's Hawks, 2 light morph calurus Red-tailed Hawks (1j,1u) and 89 Golden Eagles (50a,3sa,14j,22u). Other birds included 75 White-winged Crossbills flying south in three flocks and a late Vesper Sparrow in the meadow. The 2 Northern Shrikes (1a,1j) remain in the area and a Great Horned Owl sang.
