Cloud cover was 100-80% stratocumulus, cumulus and altostratus to 1400 after which it gradually reduced and was 30% altocumulus and cumulus at 1850.

The highest hourly count was 22 between 1500 and 1600. The combined site count was 203 migrants of 8 species that moved between 0834 and 1825 and comprised a season-high 18 Bald Eagles (12a, 2sa2, 4j), 11 Sharp-shinned Hawks (2a, 9u), 2 Cooper’s Hawks (1j, 1u), 1a Northern Goshawk, 1j light morph Broad-winged Hawk, 1a light morph calurus Red-tailed Hawk, 8 Rough-legged Hawks (7 light, 1 dark) and 161 Golden Eagles (135a, 9sa, 9j, 8u). The highest combined site hourly count was 38 between 1600 and 1700 and the previous and subsequent hours saw counts of 34 and 36 birds respectively. Other birds species were a flock of 65 Snow Geese that flew high to the SE at 1321, a flock of 44 Canada Geese that flew high to the W at 1221, 10 unidentified ducks that flew south at 1335, 2u Northern Flickers (1 Yellow-shafted and 1 Red-shafted), 2 Clark’s Nutcrackers, 5 Black-billed Magpies, 26 American Crows that flew W at 1233, 96 Common Ravens, 44 American Robins and 759 Grey-crowned Rosy-Finches (200 at Waterton 68 and flocks of 250 and 300 flying south at 1420 and 1615 respectively at Waterton 61).
