October 13 [Day 48] (Bill Wilson) The temperature rose to 6C from a low of 1C under the influence of mainly W winds that were 30-40 gusting 50 km/h for most of the day. Cloud cover was 40-95% altostratus and altocumulus all day with an arch developing in the afternoon. Conditions were ideal for eagle migration but the first bird did not appear until 0928. After 1000, however, the flood gates opened with 231 raptors moving before noon, all but 2 of them Golden Eagles. The pace slackened slightly after noon but peaked again with the passage of 125 birds (124 Golden Eagles) between 1500 and 1600. The last bird of the day was an adult Bald Eagle at 1823 which was the day’s 637th raptor, of which 626 were Golden Eagles. Because of the volume and height of the Golden Eagle movement, it proved to be impossible to assign an age to 406 (65%) of the birds. The only other raptors seen were 5 Bald Eagles, 3 Sharp-shinned Hawks and 3 Northern Goshawks: there probably wasn’t room in the sky for any more! At Mount Lorette Doug Pedersen also had a good day recording 386 Golden Eagles out of a total of 390 migrant raptors. One of the 4 non-Golden Eagle migrants was a Peregrine Falcon. Passerine movement was relatively subdued with a few flocks of grey-crowned Rosy-Finches, Pine Grosbeaks and White-winged Crossbills going south. 11.75 hours (552.33) BAEA 5 (74), SSHA 3 (1288), NOGO 3 (110), GOEA (626) TOTAL 637 (4814)
