October 8 [Day 43] The temperature only rose to 2C from a low of -2.5C, but otherwise it was a pleasant day (at least compared to yesterday!). Winds were W-WNW reaching 50 km/h around 1400 but otherwise generally between 20 and 30 km/h, cloud cover was 10-70% cumulus throughout the day and although snow squalls developed around us in the afternoon none hit the site. Movement started early with 2 Golden Eagles at 0758 and continued almost without a break until the last Golden Eagle went south at 1850. Both the combined species total of 323 and the Golden Eagle total of 300 were high counts for the season to date. Forty-five raptors (42 Golden Eagles) moved between 0800 and 0900 and by noon we had counted 161 including 152 Golden Eagles with the day’s peak movement being 60 (58 Golden Eagles) from 1100-1200. Observation conditions (with the exception of the temperature) couldn’t have been better and, unlike yesterday, I was able to age every Golden Eagle including the high fliers in the evening: 199 adults, 29 subadults and 72 juveniles. Again unlike yesterday there was a fair sprinkling of other raptors including an adult dark “Harlan’s Hawk” and the first 2 Prairie Falcons for 11 days. The single Cooper’s Hawk established a new fall seasonal record for the site of 221 birds. At Mount Lorette Cliff Hansen recorded 60 migrant raptors under somewhat adverse weather conditions, including 54 Golden Eagles and 2 adult light morph Broad-winged Hawks. Passerine migrants included 7 Red-breasted Nuthatches, 39 American Robins, 44 Grey-crowned Rosy-Finches, 5 Pine Grosbeaks, 153 White-winged Crossbills and 14 Pine Siskins. 12 hours (492.83) BAEA 2 (60), SSHA 10 (1192), COHA 1 (221), NOGO 4 (99), RTHA 3 (180), RLHA 1 (7), GOEA 300 (1890), PRFA 2 (10) TOTAL 323 (3885)
