September 27 [Day 8] (Joel Duncan) The Environment Canada weather station on the Nakiska Ridgetop to the west of the site recorded SW winds all day rarely dropping below 100 km/h, gusting between 120 and 165 km/h and peaking at 195 km/h and 193 km/h at 1200 and 1600 respectively. Wind velocities may well have been even higher on the Fisher Ranger ridge to the east! Ground winds were SW mainly 20-30 gusting 60 km/h, and cloud cover was 10-30% altocumulus giving sunny skies all day. The temperature was 15C at 0900, rose to 21C between 1400 and 1700 and was still 18C at 1900. Not surprisingly there was no obvious movement of raptors but an adult dark morph “Harlan’s Hawk” hunting above Hummingbird Plume Hill at 1116 was the first seen at the site this season and was regarded as a migrant. After drawing a blank at the Hay Meadow site, at 1615 Joel left for the Lusk Creek site to see if birds were being blown to the east, but although the wind was lighter no migrant birds were seen. Despite the winds a reasonable number of songbirds were seen including 25 Grey-crowned Rosy-Finches, 2 White-winged Crossbills, 21 Pine Siskins, 20 Yellow-rumped Warblers and a White-breasted Nuthatch, and a female or juvenile Harlequin Duck was on the Kananaskis River. 10.25 hours (84.01) RTHA 1 (8) TOTAL 1 (202)
