October 19 [Day 28] (Alan Hingston, assisted by Cliff Hansen) It was another warm day with the temperature reaching 14C at 1700 from a low of -2C and it was still 9C at 1900. Ground winds were light and variable in the morning and SW in the afternoon occasionally gusting to 20 km/h, while ridge winds were moderate SW-SSW with a high gust of 62 km/h at 1100. Cloud cover was 100% altostratus forming a Chinook Arch, that diminished to 40% as the arch moved to the east and provided observation conditions that made eagles easy to detect but difficult to age. It was another good Golden Eagle day with 145 birds (58a,4sa,7j,76u) out of a total count of 153 moving between 0811 and 1841 with a high hourly count of 33 birds (31 Golden Eagles) between 1400 and 1500 with 96 Golden Eagles moving between 1100 and 1500. Most of the movement was above the Fisher Range although several birds passed high above the valley in mid-afternoon. This was the 10th three-figure Golden Eagle count of the season. Other raptors were 3 Bald Eagles (2j and 1 undifferentiated immature bird), 2 Sharp-shinned Hawks (1a,1u), 2 juvenile light morph calurus Red-tailed Hawks and 1 Rough-legged Hawk. Other birds flying south included 1 Common Loon, 16 American Robins and 30 Bohemian Waxwings.

11.75 hours (326.4) BAEA 3 (52), SSHA 2 (76), RTHA 2 (23), RLHA 1 (21), GOEA 145 (2622) TOTAL 153 (2880)
