September 4 [Day 11] The starting temperature was 7C and with WNW to W winds persisting it felt cool for the first time this season. The temperature rose to 16C but the wind maintained its velocity until 1900 when it finally fell below 20 km/h. Cloud cover ranged from 30-90% typical of strong winds aloft with a Chinook Arch developed overhead between 1000 and 1520 and with variable amounts of altocumulus and cirrus giving excellent observing conditions. Although the day’s first raptor, a Sharp-shinned Hawk, moved at 0924 migration was again slow and sporadic until after 1600 when 9 birds moved between 1623 and 1659. Unfortunately only 1 further migrant was seen, a juvenile Northern Harrier at 1710. As yesterday, most birds were flying very high including 5 Ospreys which equals the single-day high count for the species at the site. The only migrant Golden Eagle was a late subadult at 1412, and no juvenile bird was seen with the resident pair, the male of which is still displaying on occasion. The persisting high winds resulted in an early dearth of songbirds, but at 1350 a small mixed flock of chickadees, kinglets and warblers moved slowly through the trees to the east of the site, which included a first year female Blackburnian Warbler that was present for 10 minutes in ideal light to provide a first record both for the site (the 158th bird species) and for the Crowsnest Pass area. 12.5 hours (135.58) OSPR 5 (11), NOHA 1 (29), SSHA 6 (94), COHA 4 (25), RTHA 2 (24), GOEA 1 (12) TOTAL 19 (241)
