February 18 [Day 3] (Valley View site) There was 12 cm of fresh snow on the ground after yesterday’s snowfall, and the temperature reached a high of 5C at 1300 from a low of -5.5C, falling to -3.5C at 1800 under cloudless skies. Ground winds were light all day, ridge winds were light NW becoming light to moderate after 1500, and cloud cover was mainly 50-80% cumulus and altocumulus giving excellent observing conditions, but rapidly cleared to 0% after 1700. The day’s first raptor was the season’s first Rough-legged Hawk moving south along the Livingstone Ridge at 0808, and the first migrant was an adult Bald Eagle moving north above Bluff Mountain at 1146. The resident Golden Eagle pair was conspicuous after 1150, being joined periodically by a juvenile bird which is probably their last year’s progeny, with the adult male displaying from time to time. At 1343 a migrant adult Golden Eagle soared with the resident pair before moving to the north and at 1441 an early subadult Golden Eagle glided north over Bluff Mountain. Two more adult Bald Eagles moved north at 1430 and 1628 after prolonged soaring in the warm, almost calm conditions. 10.67 hours (32.09) BAEA 3 (3), GOEA 2 (4) TOTAL 5 (8)
