November 15 [Day 55] (Cliff Hansen, assisted by Kevin Barker) The temperature high was -5C at 0800 which fell to -7C at 0900, rose to -6C in mid-afternoon and was -7C at 1700. Ground winds were light SSW to noon and variable in the afternoon, mainly light but occasionally gusting to 15 km/h, while ridge winds were moderate SW-W with gusts to 69 km/h. Cloud cover was initially 100% altostratus and cumulus that reduced to 70% between 1100 and 1300, increased to 90-100% cumulus and altocumulus to 1500 after which it dwindled to 20% at 1700. The western ridges were largely obscured to 1500 after which they cleared, and the eastern ridges were mainly clear all day. The first migrant raptor was a juvenile Bald Eagle at 1115 with the first of the day's 8 Golden Eagles (6a,1sa,1u) appearing at 1219, the last three of which went south at 1639. At 1408 a resident juvenile Northern Goshawk made a low pass from a tree perch at a European Starling over the Hay Meadow, but the starling escaped and flew low to the north. Other migrants included 23 Canada Geese, 5 white-headed gulls flying south at 1600, 52 Pine Grosbeaks (including a single flock of 30 birds) and 30 Common Redpolls.
