March 22 [Day 18] (George Halmazna) The temperature reached a high of 2.5C at 1500 from a low of -12C. Ground winds, which were initially calm became SW gusting to 40 km/h switching to N in mid-afternoon, while afternoon ridge winds were calm to E-NNE not exceeding 11 km/k. The morning was cloudless but in the afternoon cumulus and stratus cloud developed that progressively thickened and lowered obscuring 90% of the western ridges and 50% of the eastern ridges by the end of the day. The first of the day's season-high count of 222 migrant raptors appeared at 1040 and the movement peaked at 69 birds (2 Bald and 67 Golden Eagles) between 1400 and 1500 with the last bird flying north at 1634. Ninety-five percent of the movement today was along the western ridge system with birds moving from Olympic Summit on mount Allan north to Mount Collembola. The final day's count was 4 Bald Eagles (2a, 2j), 1 light morph Rough-legged Hawk and a season-high 217 Golden Eagles, all of which were adult. 11.5 hours (195.83) BAEA 4 (52), RLHA 1 (7), GOEA 217 (906) TOTAL 222 (981)


Piitaistakis-South Livingstone Raymond Tole snowshoed to the Frank Slide observation site and between 1200 and 1330 observed 2 Bald Eagles, 35 Golden Eagles and 1 Prairie Falcon before cloud obscured the ridge. A northern Pygmy-Owl also sang near the site.


After spending three days SE of the Bennett Dam in NE British Columbia (possibly being held up by adverse weather conditions), adult female Golden Eagle “Elaine” moved to the NNW and by the end of the day was in the foothills some 110 km NNW of the Bennett Dam and about 18 km SW of the Elbow of the Halfway River.
