March 28 [Day 25] (Alan Hingston, assisted by Cliff Hansen) The high temperature was 10C at 1500 and 1600, from a low of -1C at 0715, and it was 4.5C at 1900. Ground winds were mainly south 10-15 gusting 20 km/h, except in the late afternoon when brief squalls from the SW created gusts of around 40 km/h. Ridge winds were probably SW moderate to strong all day, gusting to almost 100 km/h in the late afternoon. Cloud cover was initially 100% cumulus and altostratus to 1100 after which it was 50-60% mainly cumulus giving good observing conditions. Apart from some sporadic cloud drape on the eastern ridges in the morning the mountains were clear all day. From the Hay Meadow site the observers counted a rather disappointing 51 Golden Eagles (37a,14u) between 0819 and 1835 with 34 birds seen before 1400 and only 3 moving after 1700. Because of the poor late afternoon movement Cliff moved to the Lusk Creek site between 1845 and 2010 and saw a further 10 adult Golden Eagles and a dark morph Rough-legged Hawk between 1911 and 1947; these birds are included in today’s tally. Most of these birds were flying high to the W or WNW and appeared to be heading back to the Front Range route. Other birds seen near the Hay Meadow included 16 American Robins, 50 Bohemian Waxwings, 1 Western Meadowlark and 12 Pine Grosbeaks. 12.83 hours (245.43) RLHA 1 (3), GOEA 61 (741) TOTAL 62 (792)

Beauvais Ridge (Peter Sherrington, 1210-1235) There was a short-lived movement of birds seen from my house between 1212 and 1231 involving 1 adult Bald Eagle, 1 male adult Northern Harrier, 1 light morph calurus Red-tailed Hawk and 2 adult Golden Eagles all of which glided high from the “Big Hill” towards the W or WSW. Migration conditions appeared good with a temperature of 7C, moderate to strong WSW winds and 90% cumulus and stratus cloud, but periodic checks throughout the day yielded no more birds. By mid afternoon the weather had deteriorated and the Continental Divide to the SW was mainly obscured for the rest of the day. 0.42 hours (24.5) BAEA 1 (29), NOHA 1 (1), RTHA 1 (5), GOEA 2 (132) TOTAL 5 (176)


The further adventures of “Elaine” On March 27 Elaine was in the western Pelly Mountains of southern Yukon, about 35 km NW of Little Salmon Lake which put her more or less at the same latitude as she was time last year. By March 28 she was about 75 km east of the Alaska border, WSW of Dawson, very close to where she was on this date last year.
