Wednesday, October 1, 2008

October 1 [Day 36] It was another warm day with the temperature reaching a high of 22C which is by far the highest temperature recorded at the site in October. In fact the day’s lowest temperature at 0800, 14C, was only 0.5C lower than the highest October temperature recorded at the site in the last two years! Winds were initially NW, then WNW and finally W after 1300 never exceeding 20 km/h, and we finally saw some cloud cover: 20-40% altocumulus and lenticular in the morning and 0-20% cumulus in the afternoon. Raptor movement started fairly early with 2 juvenile Golden Eagles at 0827 and peaked between 1200 and 1500 with the passage of 91 of the day’s 147 migrants, but as happened yesterday, movement declined markedly thereafter. Unlike yesterday, however, there was a late flurry of activity with 13 birds moving after 1830, with the last two Golden Eagles gliding high to the south at 1902. The late burst of activity raised the day’s Golden Eagle total to 60, and surpassed the day’s total of 56 Sharp-shinned Hawks, that continue to move strongly. The 10 Red-tailed Hawks included 4 “Harlan’s Hawks” (all dark morph adults) and the only falcons seen were 2 columbarius Merlins (1 adult male, and 1 female/juvenile). Passerine movement, while not numerous was fairly varied and included 15 Red-breasted Nuthatches, 16 Golden-crowned Kinglets, 2 Ruby-crowned Kinglets, 2 Mountain Bluebirds, 1 Townsend’s Solitaire, 70 American Robins, 2 White-crowned Sparrows, 12 Dark-eyed Juncos, 13 Pine Grosbeaks, 17 White-winged Crossbills and 107 Pine Siskins. 12.25 hours (414.42) BAEA 2 (40), NOHA 3 (45), SSHA 56 (989), COHA 8 (199), NOGO 4 (86), UA 2 (42), RTHA 10 (162), GOEA 60 (787), MERL 2 (19) TOTAL 147 (2487
