October 7 [Day 18] (Cliff Hansen) The warm weather continued with the temperature reaching 22C at 1500 from a low of -2C, ground winds were light SW all day reaching 10 km/h around noon while ridge winds were calm or light to 1400 after which they were moderate SW gusting to 40 km/h by 1900. It was cloudless to 1400 after which up to 50% lenticular cloud developed which had dissipated to 20% by the end of the day. It was another day of strong Golden Eagle movement with 274 birds (164a, 10sa, 45j, 55u) moving between 1043 and 1907 when the last bird of the day roosted at the northern end of the Fisher Range ridge. Early movement when the wind was light involved a lot of soaring over the Fisher Range involving kettles of up to 10 birds and these conditions produced the best hourly movement of the day with 78 Golden Eagles recorded between 1200 and 1300. After the ridge winds increased after 1400 birds moved to the SE very high above the Fisher Range. Other migrant raptors were 5 adult Bald Eagles, including the first migrant of the day at 1030, 4 Sharp-shinned Hawks (3a, 1u), 2 unidentified small accipiters, 2 Red-tailed Hawks of which one was an adult light morph calurus and the other an adult “Krider’s” Hawk (which is rare at the site), and 1 unidentified eagle. There was no significant non-raptor movement noted. 11.75 hours (201.92) BAEA 5 (71), SSHA 4 (48), UA 2 (9), RTHA 2 (33), GOEA 274 (1216), UE 1 (6) TOTAL 288 (1433)
Doug and Teresa Dolmen spent 7 hours at the Piitaistakis-South Livingstone site and recorded 226 migrant raptors, including 206 Golden Eagles, between 1120 and 1700, and when they left eagles were still moving south. Golden Eagle movement peaked at 92 between 1300 and 1400, while 1400-1500 yielded 42 and 1500-1600 43. Winds were moderate W all day and it was high overcast, and by 1430 the eagles were flying high and to the west of the ridge over the middle of the Gold Creek valley, which made locating and aging the birds a challenge. Other raptors recorded were 1 Osprey, 2 Bald Eagles, 9 Sharp-shinned Hawks, 1 Cooper’s Hawk, 2 Northern Goshawks, 2 unidentified accipiters and 2 unidentified eagles.
