February 23 [Day 8] (Valley View site) The temperature rose to a high of 6C for the third consecutive day, from a low of -1C, and was still 2.5C at 1800. Ground winds were NW-W gusting to 50 km/h in the morning, diminishing to 15-20 km/h in the afternoon and becoming WNW to W after 1600. Ridge winds were strong WNW to NNW to 1400 and then became moderate to strong WNW to W, and the upper flow appeared to be strong W all day. It was cloudless until 1000 when cirrus cloud began to develop reaching 80% at 1300, and for the rest of the day there was a spectacular mixture of 30-100% lenticular, altocumulus and altostratus high-wing cloud that gave an excellent backdrop to locate and identify high-flying raptors. It was the most extended raptor movement seen so far this season with 10 birds of 4 species moving between a Golden Eagle at 1041 and 2 Golden Eagles at 1755, with 7 birds moving after 1700. The flight comprised 10 Bald Eagles (6 adults, 2 subadults and 2 juveniles), 2 adult Northern Goshawks, 1 light morph Rough-legged Hawk and 6 adult Golden Eagles. The last 3 days have yielded 51 migrant raptors which is good movement for February. 11.08 hours (86.42) BAEA 10 (35), NOGO 2 (4), RLHA 1 (3), GOEA 6 (17) TOTAL 19 (59)
