February 25 [Day 10] (Valley View site) The temperature rose to 6C at 1500 from a low of -1C and fell to 2C at 1800. Ground winds were mainly NW in the morning and SW in the afternoon gusting to 30 km/h and becoming mainly light after 1400. Ridge winds were WNW moderate to strong all day, and cloud cover ranged from 40-80% cumulus, altocumulus and lenticular giving excellent observing conditions for much of the day. An adult Golden Eagle at 0958 was the earliest so far this season, but the second migrant, a subadult Bald Eagle, did not occur until 1205 after which movement was very sporadic and involved only single birds until 1713 when 2 adult Bald Eagles went N together and were the last migrants of the day. The flight comprised 9 Bald Eagles (6a,1sa,2j), a light morph Rough-legged Hawk, 3 adult Golden Eagles and the season’s first migratory Prairie Falcon at 1408. 11.25 hours (108.8) BAEA 9 (44), RLHA 1 (4), GOEA 3 (25), PRFA 1 (1) TOTAL 14 (78)
