April 23 [Day 64] (Valley View site) Heavy wet snow fell to 1030 and there was 10-15 cm of fresh snow on the ground when I arrived at the site at 1130. The temperature at 1130 was 4C but it quickly rose to a high of 11.5C as the cumulus cloud cover reduced from 70% to 0C after 1800 and by the end of the day most of the snow had melted under sunny skies. Ground winds were variable and mainly light but occasionally gusted to 15-20 km/h and ridge winds were moderate WNW. There was a fairly strong raptor movement of 27 birds between 1311 and 1626 but subsequently only 3 more migrants were seen between 1754 and 1825. The flight comprised 1 adult (or possibly late subadult) Turkey Vulture, 1 adult Bald Eagle, 1 juvenile Northern Harrier, 2 adult Sharp-shinned Hawks, 3 adult Cooper’s Hawks, 10 light morph calurus Red-tailed Hawks (9a,1j), 11 Golden Eagles (1a,3sa,7j) and 1 Prairie Falcon. Twenty-seven Tundra Swans flying above the freshly snow covered Livingstone Ridge at 1158 made a splendid sight, and the first Black Bear of the season was a brown adult that was rather conspicuous on an open patch of fresh snow on an adjacent hilltop. Tomorrow I am flying to Grande Prairie to give a talk at the annual Trumpeter Swan Festival and Bill Wilson will be at the site for the next two days. 7.75 hours (739.3) TUVU 1 (2), BAEA 1 (373), NOHA 1 (11), SSHA 2 (38), COHA 3 (11), RTHA 10 (95), GOEA 11 (2082), PRFA 1 (12) TOTAL 30 (2766)
