February 16 [Day 2] (Valley View site) The temperature rose from 1C to a high of 4C at 1300 and was still 3.5C at 1800. Ground winds were mainly NW gusting to 70 km/h at 1300 after which they moderated to 10-25 km/h. Ridge winds were strong to moderate WNW becoming moderate W after 1400, and cloud cover was 100% lenticular, altostratus and altocumulus to 1630 after which it thinned to 80% cumulus and altocumulus by 1800. The season’s first migrant raptor was an adult Golden Eagle moving north at1252, which is the earliest yet recorded at the site and the second earliest ever on a RMERF count. It was followed by an adult Northern Goshawk at 1258, also the earliest for the site, and a second adult Golden Eagle at 1322. A resident adult Golden Eagle was seen displaying between 1321 and 1634, and a second resident bird was seen at 1609. Other bird species were similar to those recorded yesterday, but today the Barred Owl sang strongly and persistently after 1748. 10.75 hours (21.42) NOGO 1 (1), GOEA 2 (2) TOTAL 3 (3)
