Weather:
The temperature was -4C at 0745, the high was 11C at 1700 and it was 4C at 1900. Ground winds were mostly calm, occasionally light SW. Ridge winds were moderate SSW-WSW for most of the day, becoming strong between 1600 and 1700 gusting to 60km/h. Cloud cover was 20% cirrus at dawn, increasing to 80% cirrus and cirrostratus at 1100 before decreasing through the afternoon to 10% at sunset. Observing conditions were moderate in the morning becoming excellent from early afternoon.

Raptor Observations:
The count was 444 birds of 5 species between 0740 and 1855 that comprised 4 Bald Eagles (3a, 1sa,), 2 American Goshawks (1a, 1u), 5 Sharp-shinned Hawks (3a, 2u), 2a light calurus Red-tailed Hawks, 1 unknown Buteo, 430 Golden Eagles (187a, 8sa, 17j, 1ui, 217u). 6 Golden Eagles were seen before sunrise and a further 34 were seen before 0840. There was a two-hour hiatus between 0900 and 1100 when only 6 birds were counted. Numbers then increased and remained high for the rest of the day. 156 Golden Eagles were seen between 1200 and 1500 and the highest hourly count occurred between 1700 and 1800 with 82 Golden Eagles. Only a single bird was seen on the western ridges all day. In the morning, most birds were located at or near Mt Lorette before gliding over to the Fisher Range, sometimes flapping hard to maintain speed but usually dropping well below ridge level after crossing the valley. This made the locating/tracking/ageing process quite challenging. By early afternoon birds were usually seen soaring over Mt Lorette, often in loose groups of 4 to 7 eagles, before gliding high and fast over the east ridges. The last Golden Eagles were seen at 1840.
