October 6 [Day
17] (Joel Duncan) It was a much warmer day with a temperature of 1C
at 0900 that rose to a high of 12.5C at 1600 and it was still 11C at
1930. Ground winds were light SW all day, occasionally calm but
averaging 2-6 km/h with a gust of 13 km/h at 1600, and ridge winds
were estimated as moderate west all day. The high wind flow, however,
still appeared to be from the north. Initial cloud cover was 100%
stratus with both the eastern and western ridges 80% obscured, but by
1100 all ridges were clear with an 80% altocumulus cloud cover that
steadily diminished to 5% by 1600. The first migrant, an unaged
Golden Eagle, was not seen until 1049, but there was a subsequent
steady flow of birds until 1910, with 28 of the day's 83 raptors
occurring between 1300 and 1400. The flight comprised 2 adult Bald
Eagles, 3 unaged Sharp-shinned Hawks, 2 unaged Cooper's Hawks, 2
light morph calurus Red-tailed Hawks (1a,1j), 73 Golden Eagles
(31a,9sa,16j,17u) and 1 probable columbarius Merlin of unknown
age/sex. With the exception of a Bald Eagle seen to the west, all
migrants moved high from Mount Lorette to the Fisher Range where most
birds gliding high above the ridge indicating good wind-lift
conditions. A good variety of non-raptor bird species was also noted
including the first Brown Creeper (1) and American Tree Sparrows (3)
of the season, 12 Golden-crowned and 2 Ruby-crowned Kinglets, 9
Yellow-rumped Warblers, 1 Wilson's Warbler, 16 White-winged
Crossbills, 8 Common Redpolls and 1 Pine Siskin. An unusual bird
behaviour was observed around noon when a male Belted Kingfisher that
was perched on a snag close to the site sallied out and caught and
ate a large moth in flight. As Joel was
preparing to leave the site at 1930 he became aware of a very large
male Moose feeding on Wolf Willows just 7 m away, and felt it prudent
to take a more circuitous route back to the parking area!

Livingstone (Peter
Sherrington, assisted by Phil Nicholas, Gerald Romanchuk and Steve
Knight) The general public were invited to join me on the ridge today
and 22 visitors and myself set off up the climb at 0920. Before most
had reached the site, however, the clouds had lowered, bringing light
snow that reduced the temperature to -1C and completely obscured the
Livingstone Ridge to the north and the mountains to the west. The
wind was NW 5-10 gusting 25 km/h, and by 1225 when the snow ended and
the ridges began to clear all but 3 of the visitors had departed.
This was unfortunate as the temperature finally rose to 5C, the wind
diminished to 5-10 km/h and had moved to the W by late afternoon and
the cloud cover gradually diminished to 60-70% cumulus by the end of
the day. Those of us who were left, however, were treated to a
movement of 120 raptors of 5 species that occurred between 1315 and
1806, with a peak movement of 83 birds between 1500 and 1700. The
flight comprised 5 Bald Eagles (3a,2j), 7 Sharp-shinned Hawks
(6a,1u), 1 unaged Northern Goshawk, 6 Rough-legged Hawks (4 light,
1dark and 1 unknown morph), 1 unidentified Buteo and 100 Golden
Eagles (60a,11sa,18j,11u). The last hour of the flight was
particularly spectacular with birds moving low overhead or close to
the ridge in bright sunshine.
