Temperature ranged from 0C to 6C

Description of the Day:

Finally, after a couple of weeks of less than ideal conditions for migrating raptors, the weather cooperated to produce a season high total of 117 Golden Eagles, almost doubling the season count to date. A low temperature of 0ºC and high of 6ºC, plus relatively calm ground winds, made the day comfortable for the observers. Cumulus clouds scudded across the sky all day in a migration-favourable mostly west to east direction, with sufficient wind that nearly all the eagles could glide effortlessly with little soaring or flapping of wings. Those few eagles that flapped their wings were assumed to be males trying to keep up with their larger and more powerful mates. Those that were seen soaring might just have been the females waiting for their mates to catch up. All the migrants were seen on the east side of the valley, ranging in height from ridge level to four "binocular views" above ridge level (not quite overhead, but close), keeping the observers on their toes. No raptors were seen on the west side of the valley, which was often obscured in clouds.
