October 6 [Day 41] For the first time this season the starting temperature was below freezing (-1C) and only rose to 5C between 1500 and 1700 despite bright sunshine all day with 5-20% cumulus cloud cover. Winds were WNW to W all day, generally 15-20 gusting 30 km/h except between 1300 and 1430 when winds gusted to 50 km/h. Despite the sparse cloud cover it was mainly located to the north of the site which greatly facilitated finding migrating raptors that generally moved high all day. The first Golden Eagle was seen at 0854 and movement was strong all day except for a minor lull between 1300 and 1400. Maximum passage was 45 birds between 1400 and 1600, but there was also a late surge with 42 birds, all Golden Eagles, moving from 1800 to 1900 and 7 more migrating high after 1900, the last bird flying at 1909 in a rapidly darkening sky. Both the combined species total of 315 and the Golden Eagle total of 273 were seasonal highs. Although other raptor movement was relatively sparse it included our latest ever record of a Broad-winged Hawk, an adult light morph, for the site, one day later than the previous latest (2006), and the 3 Cooper’s Hawks brought the season’s total to 220 equaling the previous fall record for the site (also in 2006). Passerine migration was again dominated by finches: 30 Grey-crowned Rosy-Finches, 11 Pine Grosbeaks, 312 White-winged Crossbills, 24 Common Redpolls and 54 Pine Siskins. We are now in the main period of Golden Eagle migration that should last for the next couple of weeks and assistance at the site would be greatly appreciated: the more eyes on the sky the better! 12.25 hours (468.67) BAEA 5 (57), SSHA 28 (1180), COHA 3 (220), NOGO 2 (95), BWHA 1 (20), RTHA 1 (177), GOEA 273 (1305), MERL 2 (22) TOTAL 315 (3274)
