October 21 [Day 30] (Terry Waters, assisted by Fiona Waters) The temperature high was 9C at 1600 and 1700 from a morning low of -2C and it was 7C at 1800. Ground winds were SW 10-15 gusting to 40 km/h for most of the day, and ridge winds were strong gusting between 52 and 82 km/h to 1500 after which gusts increased to between 117 and 144 km/h. Cloud cover was initially 100% altostratus and altocumulus that decreased to 50% altostratus and lenticular between 1300 and 1400 before again increasing to 80-90% altocumulus and lenticular for the rest of the day. Observing conditions were excellent for locating birds but it was often difficult to age the Golden Eagles. The day's first Golden Eagle appeared at 0845 and movement was strong in the morning and early afternoon with 28 Golden Eagles passing between 1000 and 1100 and 27 raptors, of which 22 were Golden Eagles, between 1200 and 1300. By 1600, however, the flow had almost stopped, coincident with the development of very strong ridge winds, and only 3 more birds were recorded, the last being a Red-tailed Hawk at 1710. The flight of 124 birds comprised 3 juvenile Bald Eagles, 1 adult Sharp-shinned Hawk, 1adult Cooper's Hawk, 2 adult dark morph calurus Red-tailed Hawks, 116 Golden Eagles (72a,11sa,12j,21u), which is the 11^th three-figure count this season, and 1 large unidentified falcon. Migrant songbirds included 4 American Robins, 27 Grey-crowned Rosy-Finches, 47 White-winged Crossbills and 21 Pine Siskins.
