22 [Day
48] (Bill Wilson, assisted by Cliff Hansen) The last day of the
spring 2012 count started with a temperature of -2C at 0600 that rose
to a high of 18C at 1500 and 1600 and was still 15C at 2000. Ground
winds were initially WSW (occasionally SE) 2-7 km/h, but by 0900 they
were SW gusting to 25 km/h, and after 1100 10-20 gusting 40 km/h,
while ridge winds were strong WSW to SW gusting to a maximum of 104
km/h at 1500. The count ended with the highest daily total since
April 15 with 22 birds moving between 0807 and 1958 with 14 of the
birds occurring after 1800. The first 2 birds moved along the western
ridges but the rest were generally first seen over or approaching
Mount Lorette and probably originated from Wasootch Creek having
moved to the NW below and east of the Fisher Range ridge. The flight
comprised 2 adult Bald Eagles, 2 Sharp-shinned Hawks (1j,1u), 2
Red-tailed Hawks of unknown race, morph or age and 16 Golden Eagles
(2a,1sa,10j,3u). Other birds included 1 drumming Red-naped Sapsucker,

least 22 American Pipits, 40 Bohemian Waxwings and 1 Song Sparrow. 14
