September 30 [Day 11] (Bill Wilson) The temperature was -1C at 0650 but rose to a high of 17C at 1500 and 1600, which was pleasant for the last day of September, and fell to 6C at 2000. Ground winds were variable all day, 2-10 km/h occasionally gusting to 17 km/h, and ridge winds were probably moderate WSW. Cloud cover was 80-100% cirrostratus and cumulus to 1400 after which it was mainly 10-20% altostratus, cirrus and cumulus which briefly thickened to 60% in mid-afternoon. The sky conditions were favourable to finding raptors, but many of the smaller birds were silhouettes and could not be aged. For the first time this season over a hundred migrant raptors were seen with 117 birds of a season high 10 species moving between 0825 (2 adult Golden Eagles) and 1925 (1 unaged Golden Eagle). The third and fourth eagles, however, were not seen until 1016 after which the flow of birds became steady and peaked between 1300 and 1400, during which time 25 of the 27 birds passing were Golden Eagles. All but a couple of birds appeared to be moving high from Mount Lorette to the northern end of the Fisher Range (where they were first observed), and soaring occurred at times throughout the day. The flight comprised 1 Osprey, 5 Bald Eagles (3a,2u), 2 unaged Northern Harriers, 1 unaged Sharp-shinned Hawk, 1 unaged Cooper's Hawk, 4 Northern Goshawks (1a,3u), 1 undifferentiated dark morph Red-tailed Hawk, a season high 99 Golden Eagles (49a,5sa,28j,17u), 1 unaged and unsexed columbarius Merlin, the season's first Peregrine Falcon (unaged) and 1 unidentified medium sized raptor (probably either a goshawk or a large falcon). Other birds were few but included a Great Horned Owl singing well to the north early in the morning, a Varied Thrush singing across the river, a female Belted Kingfisher and 2 Yellow-rumped Warblers.
13.16 hours (124.49) OSPR 1 (2), BAEA 5 (17), NOHA 2 (4), SSHA 1 (16), COHA 1 (4), NOGO 4 (6), RTHA 1 (11), GOEA 99 (273), MERL 1 (4), PEFA 1 (1) UU 1 (1) TOTAL 117 (342)


Piitaistakis-South Livingstone (David McIntyre) During a walk from their home south to HW 3 via Tallon Peak (which is just east of the southern end of the Livingstone ridge) David and his wife Monica observed a south-bound adult Turkey Vulture at around 1615. This is the first fall record of the species on the route, and equals the total seen in the fall in 20 years at Mount Lorette.
