April 9 [Day 52] (Valley View site) It was a cool day with the temperature only briefly reaching 1C at 1400 from a low of -5C, ground winds were WNW to SW gusting 40-60 km/h in the afternoon and ridge winds were W moderate to strong. Cloud cover was 30-90% cumulus and altocumulus until 1500 after which it became 100% stratus with periods of snow resulting in periodic obscuring of the ridges. It was yet another day of poor raptor movement with snow generally persisting to the south even when the ridges were clear. Only 5 birds moved between 0828 and 1706: 1 adult Bald Eagle, 1 adult male Northern Harrier and 3 adult Golden Eagles, although non-migrant Northern Goshawk, Red-tailed Hawks, Golden Eagles and Prairie Falcons were fairly conspicuous during non-snowy periods. 11.25 hours (605.4) BAEA 1 (337), NOHA 1 (4), GOEA 3 (1984) TOTAL 5 (2502)
Mount Lorette [Day 40] (Jim Davis, Cliff Hansen after 1400) The temperature rose to 4C at 1300 from a low of -5C but quickly fell to 0C as light snow began to fall at 1300 becoming steady snow after 1500 which obscured all ridges for the rest of the day. Ground winds were light SW in the morning gusting to 30 km/h by mid-afternoon, and ridge winds were moderate to strong SW. A total of 7 birds moved between 0957 and 1318, 4 of which were recorded between 1000 and 1100, the flight comprising 1 late subadult Bald Eagle, 1 adult Northern Goshawk and 5 Golden Eagles (4a,1u). 10.75 (449.5) BAEA 1 (78), NOGO 1 (20), GOEA 5 (1122) TOTAL 7 (1252)
