October 7 [Day 40] (Bill Wilson) Winds were WNW to W all day gusting to over 80 km/h in early afternoon but dropping to 50-60 km/h by late afternoon. The temperature ranged from 0.5C to 3.5C and altocumulus/cumulus cloud cover increased from 30% in early morning to 90% by the end of the day. As yesterday the Livingstone Range to the north was shrouded in cloud all day, but when I drove down from Cochrane in the late afternoon the Front Ranges were clear the whole way except for the 4 km north of the observation site! As yesterday the cloud did not appear to deter movement with the first Golden Eagle appearing at 0753 and steady movement to 1300, after which the rate increased peaking at 54 birds between 1400 and 1500. The last Golden Eagle of the day at 1837 was the 257th and was the 278th migrant. Two large falcons that came through late in the gathering gloom might have been Peregrines. For the first few hours there appeared to be two layers of cloud above the site and eagles seemed to flying between them: it is possible that some birds were (gasp!) missed. Again passerine movement was almost non-existent but included 2 Yellow-rumped Warblers, the latest recorded at the site. 12.5 hours (442.6) BAEA 6 (69), SSHA 6 (644), COHA 2 (167), NOGO 1 (33), UA 1 (55), GOEA 257 (1500), UE 2 (3), UF 2 (2), UU 1 (3) TOTAL 278 (2803)
