October 25 [Day 34] (George Halmazna) Another cool day with a temperature of -10C to 0900 and a high of 3C at 1400 and 1500. It was calm to light SW until late morning when gusts of 15-25 km/h were experienced until 1400 after which they were again light, with afternoon winds varying between SE and NW. Ridge winds were consistently SW-WSW, generally moderate with gusts only occasionally above 50 km/h. It was cloudless to 1100 after which the cover was 20-60% cumulus for the rest of the day but the cloud was often in “the wrong places” meaning that birds often had to be located in a plain blue sky. Despite this the combined species count of 175 was the 6th highest of the season, with birds mainly moving along the Fisher Range at altitudes ranging from low to very high, with a few birds moving along the western ridges and some high above the middle of the valley. The movement started late with the first Golden Eagle not appearing until 1115 but it then rapidly built up with 60 birds (57 Golden Eagles) moving between 1200 and 1300. The last Golden Eagle was counted at 1744 and the day's last bird was a Bald Eagle at 1810. The total of 156 Golden Eagles (115a,6sa,16j,19u) was the highest since October 17, the 12 Bald Eagles (8a,4j) was the highest so far this season, and other raptors were 5 Sharp-shinned Hawks (1a,1j,3u), 1 adult Northern Goshawk and 1 light morph Rough-legged Hawk. Finches were again the most common non-raptor comprising 7 Evening Grosbeaks, 31 White-winged Crossbills, 74 Common Redpolls and 14 Pine Siskins.

11.5 hours (394.6) BAEA 12 (86), SSHA 5 (106), NOGO 1 (32), RLHA 1 (30), GOEA 156 (3206) TOTAL 175 (3546)
