August 27 [Day 3] It was another warm sunny day with the temperature ranging from 12C to 18C. Winds were variable but mainly from the E, and generally light and even, on occasion, calm. Cloud cover varied from 5 to 50% cirrostratus, altostratus, altocumulus and cirrus giving good to excellent viewing conditions. Raptor movement was strong for this early in the season with 37 migrants of 12 species moving between 1126 and 1854 providing the third highest August count for the site. The gentle upslope winds probably contributed to the occurrence of 3 light morph unaged Swainson’s Hawks and 3 light morph Ferruginous Hawks (2 adults and 1 juvenile), the previous seasons’ high for both species at the site was just one! Also moving for the first time this season were 1 Osprey, 2 juvenile Bald Eagles, 6 juvenile Northern Harriers, 1 juvenile Coopers Hawk, 2 juvenile Northern Goshawks, a juvenile light morph Broad-winged Hawk and a subadult Golden Eagle, while Sharp-shinned Hawks (9) and American Kestrels (5) registered their highest counts to date. A non-migratory juvenile Golden Eagle was seen at 1538, but as it was chased away by the resident adult pair it is unlikely that it was their progeny. The total bird count for the day was 45 species including an excellent movement of passerines in the morning. These included 1 Western Wood-Pewee, 1 Least Flycatcher, 1 Dusky Flycatcher, 2 Cassin’s Vireos, 3 Warbling Vireos, 23 red-breasted Nuthatches, 1 White-breasted Nuthatch, 26 Golden-crowned Kinglets, 38 Ruby-crowned Kinglets, 5 Mountain Bluebirds, 4 Townsend’s Solitaires, 5 American Robins, 1 Tennessee Warbler, 23 Yellow-rumped Warblers, 8 Townsend’s Warblers, 1 Palm Warbler ( the earliest ever at the site), 1 Common Yellowthroat, 4 Wilson’s Warblers, 16 Chipping Sparrows, 1 Brewers Sparrow, 1 Clay-coloured Sparrow, 1 White-crowned Sparrow, 2 Oregon Juncos and 26 Pine Siskins. Clark’s Nutcrackers also moved south steadily throughout the day with 18 of the day’s 27 birds flying in a single flock at 1035. The first three days of the count have produced a total of 51 bird species: not bad for a narrow ridge at 1,900 m. 12.67 hours (37.67) OSPR 1 (1), BAEA 2 (2), NOHA 6 (6), SSHA 9 (14), COHA 1 (1), NOGO 2 (2), BWHA 1 (1), SWHA 3 (3), RTHA 2 (5), FEHA 3 (3), UB 1 (1), GOEA 1 (1), AMKE 5 (7) TOTAL 37 (49)
