October 5 [Day 16] (Jim Davis, assisted by Cliff Hansen) The temperature was -2C at 0700 and rose to a high of 10C at 1400 and was still 9C at 1610 when the count was terminated because of heavy rain. Ground winds were calm to 1300 then E-NE 5-7 km/k thereafter, and ridge winds were S-SW moderate to 1300 after which they were NE-ENE 4-12 km/h. Cloud cover was 10-20% altostratus to 1300 after which it thickened and lowered from the south to 90% stratus and was100% after 1500. Steady rain started at 1506 finally obscuring all the ridges that started to be draped by cloud after 1500. The first migrant was a Sharp-shinned Hawk at 0753 which flew low to the south above the river, the last bird was also a Sharp-shinned Hawk at 1459 and the highest hourly count was 10 birds between 1300 and 1400. Only 6 birds moved above the western ridges while the rest moved south above the Fisher Range to the east. After yesterday's count the total of only 23 migrants was disappointing and comprised 5 Bald Eagles (3a,2j), 7 Sharp-shinned Hawks (1j,6u), 2 unaged Cooper's Hawks, 2 light morph calurus Red-tailed Hawks (1a,1j), 5 Golden Eagles (4a,1j) and 2 adult Peregrine Falcons. The non-raptor highlight was a Belted Kingfisher chasing a juvenile Northern Shrike, and other birds included 3 Ruby-crowned Kinglets, 6 Yellow-rumped (Myrtle) Warblers, 9 Dark-eyed Juncos (9 slate-coloured morphs and 1 Oregon morph), 19 Grey-crowned Rosy-Finches and 42 Pine Siskins.

9.25 hours (185.15) BAEA 5 (21), SSHA 7 (48), COHA 2 (8), RTHA 2 (8), GOEA 5 (389), PEFA 2 (8) TOTAL 23 (501)
