October 4 [Day
15] (Cliff Hansen, assisted by Kevin Barker, Cliff Hansen and Michael
Woertman) The temperature was -4C at 0730 but fell under cloudless
skies to a season-low -9C at 0800, but rose to a high of 5C at 1600
at was 1.5C at the end of the day. Ground winds were variable all day
calm to light occasionally reaching 12 km/h, and ridge winds were
assessed as W light to moderate. It was cloudless to 1200 when
cumulus developed that reached 50% at 1600 before dwindling to 10% at
the end of the day. The first Golden Eagle was not seen until 1112
but subsequently there was a steady stream of raptors passing high
overhead from Mount McGillivray to Old Baldy until 1813 after which
the last 12 birds of the day moved on the usual route from Mount
Lorette to the north end of the Fisher Range, where the last bird of
the day, an unidentified Buteo, was seen at 1845. The flight
of 82 birds comprised 5 adult Bald Eagles, a season-high 15
Sharp-shinned Hawks (7a,2j,6u), 1 adult Cooper's Hawk, 1 unidentified
Accipiter, the season’s first Rough-legged Hawk (a light
morph), 1 unidentified Buteo and 58 Golden Eagles
(31a,4sa,9j,14u). Forty-five of the migrants were recorded before
1400 after which the pace slackened somewhat and only picked up again
between 1800 and 1845 when the last 12 birds passed. Without the eyes
of the three assistants scanning directly overhead the day's total
would probably have been somewhat lower! Non-raptor bird species
included a southbound flock of 14 female,juvenile Common Mergansers,
6 Clark's Nutcrackers flying to the south, 3 Golden-crowned and 2
Ruby-crowned Kinglets, only 4 American Robins, 3 Wilson's Warblers,
53 White-winged Crossbills and 30 Pine Siskins. An adult Black Bear
was also seen on the northern end of Hummingbird Plume Hill.
