March 25 [Day 22] (Bill Wilson) The temperature was -12C at 0700, rose to a high of 11C at 1600 and 1700, and was 2C at 1950. Ground winds were SW 2-10 gusting 20 km/h all day, and ridge winds in the afternoon were SSW-WSW 5-24 gusting 40 km/h. It was cloudless to 1100 after which 50-80% altostratus developed to 1300 becoming 100% to 1700, after which it was 10-50% cirrostratus to the end of the day. After yesterday's late eagle movement an early start today was to be expected but the first Golden Eagle was not recorded until 1157 and by 1600 only 11 Golden Eagles had been counted. Things subsequently picked up, however, and a further 53 Golden and 6 Bald Eagles were seen, with 27 birds (2 Bald Eagles and 25 Golden Eagles) occurring between 1800 and 1900, and the last 2 Golden Eagles moved to the NW at 1908. The final count of 70 raptors was 6 Bald Eagles (3a,3j) and 64 Golden Eagles (58a,1sa,5u). Non-raptor species included 3 American Robins, 1 singing Dark-eyed [Oregon] Junco and 6 Pine Grosbeaks. 12.83 hours (212.85) BAEA 6 (31), GOEA 64 (541) TOTAL 70 (579)


Beauvais Ridge (Peter Sherrington, 1430-1700) The temperature during the period fell from 2C to -1C, winds were N-NE 5-10 gusting 15 km/h and cloud cover was 100% very thin cirrostratus giving hazy sun. There was a fairly steady movement of raptors between 1443 and 1649, the flight comprising 5 adult Bald Eagles, 1 unaged Cooper's Hawk, 1 adult light morph calurus Red-tailed Hawk and 53 Golden Eagles (50a,3sa). A light morph Rough-legged Hawk was considered a non-migrant. The birds all appeared low over the ridges to the east, soared high then flow with mainly flapping flight and little gliding either to the W or to the WNW. A migrating Northern Shrike flew high to the north at 1606. 2.5 hours (21.08) BAEA 5 (10), COHA 1 (1), RTHA 1 (3), GOEA 53 (99) TOTAL 60 (114).
