October 22 [Day 32] (Terry Waters) Unseasonably high temperatures continued reaching 13C at 1500 from a low of -5C and remaining at 12C at 1800. Ground winds were light variably, but mainly SW and ridge winds were SW-S moderate to strong gusting to 90 km/h. An initial cloud cover of 10% cirrus increased to almost 100% altocumulus by 1200 becoming 90% stratocumulus after 1600 providing an excellent backdrop against which to locate birds. Of 69 migrant raptors recorded 65 were Golden Eagles (41a, 9sa, 7j, 8u) that moved between 0920 (the only bird moving west of the site) and 1801. Morning movement was slow but became steady in the afternoon with peak movement of 15 birds between 1700 and 1800. Other migrants were 2 adult Bald Eagles, 1 adult Sharp-shinned Hawk, and an adult Peregrine Falcon flying south at 1431. Passerine migrants included 26 Bohemian Waxwings, 35 European Starlings and 22 Grey-crowned Rosy-Finches, and 2 White-throated Sparrows were the first reported from the site this season. 10 hours (355.91) BAEA 2 (87), SSHA 1 (59), GOEA 65 (2480), PEFA 1 (4) TOTAL 69 (2778)
