April
1 [Day
29] (Bill Wilson) The temperature at 0730 was 0C, rose to a high of
6C at 1600 and fell to 1C at 2000. Surface winds were SW 5-15 gusting
35 km/h decreasing in the last couple of hours of counting and were S
2-5 at the end of the day, while ridge winds were strong SW gusting
to 104 km/h to 0800, then mainly moderate SW gusting to 45 km/h to
1700 after which they were variably W-S light. Cloud cover was
essentially cumulus all day, initially 5%, then 30-60% between 0900
and 1200 and 80-100% for the rest of the day giving good observing
conditions. The only precipitation was a few flurries after 1900, but
there was 3 cm of fresh snow on the ground at the start. The western
ridges were obscured up to 20% throughout the day, but the east
remained clear except during brief snow squalls late in the
afternoon. A total of 58 migrant raptors were recorded between 0824
and 1825, with the flight peaking at 10 birds (2 Sharp-shinned Hawks,
1 Northern Goshawk and 7 Golden Eagles) between 1300 and 1400,
although the maximum Golden Eagle passage was 9 between 1000 and
1100. All the birds moved high from the Fisher Range to Mount
Lorette, although late in the day they were only seen after they had
arrived at Mount Lorette. The flight comprised 1 adult Bald Eagle, 3
unaged Sharp-shinned Hawks, 2 Northern Goshawks (1a,1u), 2 adult
light morph calurus
Red-tailed Hawks (the 3 former species each having their highest
counts for the season), 1 indeterminate Buteo
and 49 Golden Eagles (39a,3sa,2j,5u). The Northern Shrike still
lingered around the meadow, 2 Varied Thrushes sang and 12 of the
day's 17 American Robins flew north in a single flock. 13.16 hours
(284) BAEA 1 (43), SSHA 3 (6), NOGO 2 (3), RTHA 2 (3), UB 1 (2), GOEA

The
further adventures of “Elaine” Today
Elaine moved to the WNW and finished the day near the headwaters of
the North Fork of the Salcho River, about 130 km E of Fairbanks. She
is now some 300 km SSE of where she was on this date last year.
