October 16 [Day 51] It was another ideal day for eagle migration, if a little chilly for observation with the temperature only rising briefly above freezing to a high of 3C from a low of -2C. Winds were WNW to W all day gusting to 40 km/h up to 1330 and then increasing to 60-80 km/h for the rest of the day. Cloud cover was a spectacular variety of constantly changing high wind clouds: lenticular altostratus, altocumulus, cirrus and cumulus, which produced good to excellent viewing conditions throughout the day and a superlative sunset in the evening. Against this backdrop was a constant stream of mainly Golden Eagles that started at 0825 and finished at 1840 without a single significant break. Until 1000 the movement was low along the ridge with the birds passing very close, but as the winds increased movement became progressively higher although many birds still passed overhead. The combined species total of 384 and the Golden Eagle total of 357 were both the second highest of the season, and again there was a fair leavening of other raptors. The evenness of the movement is shown by the hourly counts between 0900 and 1800 which ranged between 28 and 49 birds/hour. At Mount Lorette Brian McBride counted 178 migrant raptors between 0810 and 1842, of which 167 were Golden Eagles and 9 were unidentified eagles which were also probably Golden Eagles. Passerine movement was confined to finches with 147 Grey-crowned Rosy-Finches, 16 Pine Grosbeaks, 3 Red Crossbills and 111 White-winged Crossbills moving south. 11.75 hours (587.25) BAEA 7 (90), SSHA 9 (1343), NOGO 5 (126), RTHA 1 (190), RLHA 4 (29), UB 1 (2), GOEA 357 (3512) TOTAL 384 (5760)
