November 3 [Day 43] (Cliff Hansen) Joel was the designated Principal Observer today, but was unwell and phoned Cliff who arrived at the site at 1150 when the temperature was still 0C before it rose to a high of 11C at 1600 and was still 4C at 1800. Ground winds were light SW all day, as were ridge winds in the morning after which they became moderate to strong gusting 55 km/h by late afternoon. It was cloudless until 1600 when 10% altocumulus developed that reached 40-50% after 1700. The morning’s calm conditions suggested that despite the late start it is unlikely that birds were missed. The first of the day’s 69 migrants wasn’t seen until 1308 after which movement was brisk with 23 more birds recorded before 1400, 26 between 1400 and 1500, and a further 19 migrants were seen after 1500 with the last passing at 1759. The flight comprised 10 Bald Eagles (8a, 1sa, 1j), 2 unaged Northern Goshawks, 54 Golden Eagles (34a, 1sa, 13j, 6u) and 3 unidentified eagles. There was no passerine movement but a flock of 50 Bohemian Waxwings fed on an insect hatch above the Kananaskis River. 6.83 hours (463.73) BAEA 10 (122), NOGO 2 (30), GOEA 54 (2983), UE 3 (12) TOTAL 69 (3346)
