March 23 [Day 19] (Jim Davis) The temperature at 0900 was -3C and rose to a high of 2C at 1700. Ground winds were light N for most of the day occasionally gusting to 15 km/h, and ridge winds were calm to light SW to 1600 when they changed to SSE 14-16 km/h. Cloud cover was 100% stratocumulus for most of the day diminishing at times to 70-80% in the late afternoon, with the ridges obscured or draped for most of the day. Birds either moved below the cloud base or, on occasion, flew above the cloud when the ridges were obscured but the peaks remained clear. Heavy snow fell between 1600 and 1645 and light snow persisted for the rest of the day making the aging of birds impossible at times. The first migrant raptor of the day was a Bald Eagle at 1044 but the second bird, a Golden Eagle, did not appear until 1402 with the hour producing 29 migrants (2 Bald and 27 Golden Eagles). Between 1500 and 1600 a season-high 114 birds were recorded, all of which were Golden Eagles. Between 1600 and 1700, however, only 5 birds were seen and it is probable that eagles were moving in clear air above the stratocumulus layer as they could be occasionally glimpsed through small breaks in the cloud. Between 1700 and 1800 42 birds moved (6 Bald Eagles, 35 Golden Eagles and 1 unidentified eagle) and 1800-2000 yielded 30 more (30 Golden Eagles and 1 unidentified eagle). All but about 15 birds moved on the eastern route and the light winds produced much soaring flight with kettles of up to 36 Golden Eagles forming, waiting for clouds to clear so they could progress, rather analogous to rush-hour cars waiting for traffic lights to turn green. The combined species total of 222 equals yesterday's season high and comprised 9 Bald Eagles (4a, 5j), 211 Golden Eagles (165a, 4sa, 2j, 40u) and 2 unidentified eagles. As if this were not enough the day also produced the season's first Western Meadowlark, 9 American Robins, 150 Bohemian Waxwings, 1 Northern Flicker and a Trumpeter Swan that flew low to the north above the river. 10.25 hours (206.08) BAEA 9 (61), GOEA 211 (1117), UE 2 (6) TOTAL 222 (1203)
