April
15
[Day 41] (Bill Wilson) Yesterday's
weather persisted to 1100 when the very light snow stopped and the
ridges slowly began to clear. The temperature at 0605 was -5C, rose
to 1C between 1400 and 1800 and dropped to -1C at 2000. Ground winds
were N-NNE 2-10 gusting 20 km/h all day, while ridge winds were
WSW-SW light to moderate. The 100% stratus cloud cover persisted to
1100 when it reduced to 60% stratus and cumulus and at 1300 and 1400
it was down to 30% before it again thickened to 100% slightly broken
stratus for the rest of the day after 1500. The eastern ridges began
to emerge from cloud at 1100 when they were 10% visible and slowly
increased to 20% clear at 1300 and were completely clear at 1700,
while the western ridges were 100% obscured to 1300, became 20%
visible at 1600 and did not fully clear until 1900. Despite the
conditions, the first bird of the day, an adult male Northern Harrier
flew north at 0941, the first 2 Golden Eagles followed at 0955 and 12
migrants had been seen before the ridges started to clear at 1100.
Almost all of the 49 migrant raptors recorded moved low below the
cloud in front of the flanks of mount Allan to the west, while after
1543 the birds were located over Hummingbird Plume Hill before they
moved to the NW over Skogan Pass, or flew to the NE past the south
face of Mount Lorette. Several birds soared high into the low cloud
and were not seen again. The combined species count of 49 was the
highest since April 7 and comprised 1 adult male Northern Harrier, 2
Sharp-shinned Hawks (1a,1u), 1 adult Cooper's Hawk, 4 Northern
Goshawks (2a,2u), 2 Red-tailed Hawks (1 adult light morph calurus
and
1 undifferentiated dark morph) and 38 Golden Eagles (11a,7sa,15j,5u),
the latter being the highest count since April 6. The highest single
hour count was 12 (3 Northern Goshawks, 1 Red-tailed Hawk and 8
Golden Eagles) between 1100 and 1200, and the 2 Golden Eagles seen at
1543 finally put the season's total for the species above 1000 which
is about 1600 below the average total for this time. Songbirds seen
at the site included 1 Northern Shrike, 2 Townsend's Solitaires, 4
Mountain Bluebirds, 170 American Robins, 28 Dark-eyed Juncos and 1
Western Meadowlark. 14.25 hours (418.32) BAEA 1 (80), NOHA 1 (2),
SSHA 2 (20), COHA 1 (6), NOGO 4 (16), RTHA 2 (44), GOEA 38 (1008)
TOTAL 48 (1208)
