February 27 [Day 12] (Valley View site) (Bill Wilson) It was the warmest day so far this season with the temperature reaching 9C at 1300 from a morning low of 4C, and it was still 5C at 1800. Ground winds were very variable, mainly light to mid afternoon and strengthening to 25 km/h after 1600 and ridge and upper winds were moderate W all day. Cloud cover was 100% cumulus and altostratus to noon, thinning to 50-90% with development of cirrus cloud in the afternoon. Raptor movement got off to a brisk start with 2 Bald Eagles, 2 Northern Goshawks and a Golden Eagle moving between 0942 and 1000. Subsequent movement, however, was persistent but sparse with no further hourly count exceeding 2 birds and the last bird, a Bald Eagle, went north at 1710. The 5 Bald Eagles and 2 goshawks seen were all adults while the 8 Golden Eagles comprised 5 adults, 1 subadult and 2 juveniles. 11.16 hours (131.2) BAEA 5 (61), NOGO 2 (7), GOEA 8 (42) TOTAL 15 (120)
