September 28 [Day 33] (Bill Wilson) It was a day of stable high pressure conditions with a temperature high of 13C rising from a low of 5C and mainly W winds that were generally light to 1400 then become moderate gusting on occasion to 30 km/h. Cloud cover was altostratus all day, diaphanously thin in the morning and thickening slightly in the afternoon, but enough to make detection of raptors reasonably easy. The early morning light winds were not conducive to raptor movement and only 3 birds were seen before 1100, but thereafter the pace quickened with an average of 24 birds/ hour seen between 1100 and 1900 with maximum passage of 38 birds from 1600 to 1700. Golden Eagles (105) again dominated the flight and all three Accipiter species moved strongly. A single Osprey raised the season’s total to a record 24 and the season’s first Rough-legged Hawk was seen on exactly the same day as last year, and one day earlier than in 2006. Two of the day’s 8 Red-tailed Hawks were “Harlan’s” and 2 adult Peregrine Falcons brought the season’s total to 25. Passerine movement was dominated by White-winged Crossbills and American Robins, and 5 Yellow-rumped Warblers and 22 Mountain Bluebirds (in one flock) were the highest counts for 8 and 5 days respectively. The songbird of the day, however, was undoubtedly the 3rd Grey-cheeked Thrush of the season that uncharacteristically perched in the open for 2 minutes allowing close scrutiny, and was only finally displaced by an incoming American Robin that took over its perch. 12 hours (377.92) OSPR 1 (24), NOHA 1 (35), SSHA 55 (806), COHA 8 (177), NOGO 10 (77), UA 4 (40), RTHA 8 (137), RLHA 1 (1), GOEA 105 (533), PEFA 2 (25), UU 2 (14) TOTAL 196 (1966)
