March 21 [Day 30] Winds were WNW-W moderate to strong all day with 40-100% generally cumulus and altostratus cloud cover. After 1700 light flurries developed from the west with a period of snow from 1840-1910 when everything was obscured. The temperature range was -3C to 3C with the wind once again making for uncomfortable viewing. Raptor movement started slowly with the first Golden Eagle at 0858 and the rate only increased between 1500 and 1800 when 118 of the day’s 194 migrants moved. Just when it was looking like it would be a new season-high count the snow started and after it finished only two more birds went north: a Golden Eagle at 1924 and the second Merlin of the season at 1932. The resident Golden Eagle pair was obvious for much of the day, including displays over both nest sites: on two occasions the birds were observed to touch talons, but did not grasp. The only apparent passerine migrants were a total of 49 Grey-crowned Rosy-Finches, and the first Varied Thrush of the season sang briefly at 0821. 12 hours (314.1) BAEA 7 (226), NOGO 6 (42), RTHA 1 (7), RLHA 1 (11), GOEA 178 (1627), MERL 1 (2) TOTAL 194 (1928)

Mount Lorette (Des) The temperature rose to 5C from a low of -10C; winds were light NW in the morning becoming moderate in the afternoon, and thin cirrus cloud cover in the morning gave way to cumulus increasing to 80% in the afternoon before completely clearing late in the day. The only migrant raptors were Golden Eagles seen between 0923 and 1940. Most of the birds migrated high overhead down the valley in the morning, but moved increasingly to the east as the day progressed. Non-raptor highlights included over 400 (probable) California Gulls flying high to the east across the Fisher Range, and the first singing Song Sparrow of the year. 12 hours (229.7) GOEA 73 (860) TOTAL 73 (912)
