October 28 [Day 37] (Bill Wilson) For the first time since October 20 the temperature at the site rose above freezing, with a high of 7C at 1400 from a morning low of -7.5C, and it remained at 5C at 1845. Ground winds were initially variable and light to 0930 and then WSW 5-15 gusting 33 km/h for the rest of the day, while ridge winds were moderate to strong W after 1100 resulting in snow pluming from the eastern ridges. Cloud cover was 50-100% cumulus all day and some very light snow blew in from the west between 1400 and 1600, and again at the end of the day. Apart from a couple of birds that flew south overhead all of the day’s 42 migrant raptors moved above the eastern part of the valley or along the Fisher Range between 0848 and 1809. Movement was fairly steady all day with a maximum hourly movement of only 7 birds between 1100 and 1200. The flight comprised 4 Bald Eagles (3a,1j), 1 unaged Northern Goshawk and 37 Golden Eagles (26a,1sa,4j,6u). other birds were scarce, but included 26 Canada Geese in a single flock, 3 Mallard, 1 Common Merganser and 1 American Robin.
