November 5 [Day 45] (Jim Davis) The temperature reached a high of -1C at 1500 from a low of -8C and was down to -4C at 1810. Ground winds were calm to 1500 after which it was SW 8-11 km/h for the rest of the day, while ridge winds were also light SW and even occasionally calm. It was cloudless to 1500 after which it gradually increased to 20% altocumulus and cirrocumulus by 1800. Raptor movement started slowly with the first bird, a Northern Goshawk, not appearing until 1104 and the first Golden Eagles were not seen until 1341, Movement, however, steadily increased throughout the afternoon and peaked at 24 birds between 1600 and 1700, and by the time the last Golden Eagle went south at 1746 a total of 59 migrants of 7 species had been recorded, which is the highest count at the site since October 25. All the birds moved along the eastern route and were mainly picked up moving from Mount Lorette to the northern end of the Fisher Range. The count included a very late Osprey which was just the 3rd of the season (the 2nd being on October 3), is a first record for November and is by far the latest ever recorded at the site. Other migrants were 10 adult Bald Eagles, 2 unaged Cooper's Hawks, 1 unaged Northern Goshawk, 1 adult dark morph harlani Red-Tailed Hawk, 3 light morph Rough-legged Hawks and 41 Golden Eagles (13a,3sa,14j,11u) which is the highest count since October 31 which was also 41 birds. Today yet again demonstrates the importance of continuing even when when several days of low counts make it appear that migration is essentially over. Other birds seen included 1 American Robin, 10 Grey-crowned Rosy-Finches, 20 White-winged Crossbills and 11 Common Redpolls.

7.5 hours (498.61) OSPR 1 (3), BAEA 10 (117), COHA 2 (33), NOGO 1 (37), RTHA 1 (28), RLHA 3 (36), GOEA 41 (3405) TOTAL 59 (3804)
