November 17 [Day 82] (Dawn Hall/Raymond Toal) Observations were made from the Valley View site with the assistance of Nel and Keith. A starting temperature of -1C quickly warmed to 12C by noon before gradually cooling to 6C by 1700. Valley bottom winds were W generally 10-25 km/h, but the winds on the ridge appeared to be strong (40 km/k +) all day. Cloud cover was 90% altostratus until 1100 making aging of the day’s first 7 Golden Eagles impossible, but then thinned to 70% altocumulus and after 1300 was 50% cirrus providing an excellent observation backdrop. It was another good November raptor migration similar to that of November 15 with only 3 adult Bald Eagles but 26 Golden Eagles that moved fairly steadily between 0820 and 1630. Recently most of the Golden Eagles recorded have been adults, but today of the 19 birds to which ages could be assigned 3 were subadults and 7 juveniles. Two Buteos also moved in the morning when the light conditions precluded specific identification. The combined species total has now exceeded 8,000 for the second successive year, and we reached this mark 5 days later than in 2007. Just before noon an apparent non-migrant juvenile Golden Eagle launched an attack on two Bighorn rams on Ent Ridge that simultaneously reared up to fend off the attack, after which the eagle flapped off to the north. 9.25 hours (920.39) BAEA 3 (380), UB 2 (9), GOEA (5097) TOTAL 31 (8017)
