October 24 [Day 33] (George Halmazna) It was another cool day with a starting temperature of -8C, a high at 1500 of 4.5C and 0C at 1900. Ground winds were were mainly light but briefly gusted to 25 km/h in mid-afternoon, and varied from SW-NE throughout the day, while ridge winds were also mainly light, SW to variable, only becoming moderate at 1900. Initial cloud cover was 10-30% cumulus thickening to 100% stratus and cumulus after 1600, which reduced to 80% cumulus by 1900. Snow flurries developed after 1300 becoming snow between 1700 and 1830 that largely obscured the ridges which only partially cleared again after 1830. Despite the relatively calm conditions and afternoon snow it was again a good raptor movement with 132 birds of 5 species moving between a Northern Goshawk at 0812 and 2 Golden Eagles at 1641 and a Sharp-shinned Hawk at 1643 moving ahead of the snow, with a maximum hourly count of 28 (23 Golden Eagles) between 1500 and 1600. The flight was dominated by 102 Golden Eagles, the 13th three-figure count of the season, which comprised 83 adults, 7 subadults, 9 juveniles and 3 birds of unknown age. Season-high counts were achieved for Bald Eagle (10: 8a,2j) and Sharp-shinned Hawk (14: 2a,2j,10u), while the rest of the total was made up of 1 unaged Cooper's Hawk and 5 Rough-legged Hawks (4 light and 1 dark morph). There were also good numbers of other bird species seen including 6 Clark's Nutcrackers, 2 Brown Creepers, 7 Pine Grosbeaks, 113 White-winged Crossbills and 246 Pine Siskins, while a single flock of 23 Common Ravens flying east from Mount Lorette briefly had George contemplating a 200+ Golden Eagle day!

11.25 hours (383.11) BAEA 10 (74), SSHA 14 (101), COHA 1 (30), RLHA 5 (29), GOEA 102 (3050), TOTAL 132 (3371)
