March 26 [Day 35] It was the most pleasant day in a while and actually felt spring like on occasion. The temperature briefly rose to 5C from a low of -10C, and W-SW winds were generally light to moderate both in the valley and aloft. The sky to 1030 and after 1700 had 100% altostratus cloud cover, but between we had 10-60% cumulus giving plenty of sunshine. The relatively calm conditions again precluded early movement and the first Golden Eagles did not appear until 1050 and subsequent movement often involved prolonged periods of soaring flight making migrants on occasion difficult to distinguish from resident birds. Movement was again fairly slow and steady with peak movement of 16 birds from 1400 to 1500, and the last Golden Eagles went north at 1911. The first Sharp-shinned Hawk of the season sped to the north at 1439, and 4 adult Red-tailed Hawks (1 dark harlani, 3 light calurus) was the highest count so far. The Golden Eagle at 1872 was the 2000th of the season, and the total of 62 birds included 4 subadults and 3 juveniles, the highest percentage of immature birds so far. The season’s total of 277 Bald Eagles now exceeds by one the highest ever complete spring count at Mount Lorette achieved in 2001. Passerine movement was confined to a single flock of around 250 Grey-crowned Rosy-Finches, and a Townsend’s Solitaire sang for the first time this year. 12.25 hours (373.2) BAEA 7 (277) SSHA 1 (1), RTHA 4 (14), GOEA 62 (2004), UE 1 (7) TOTAL 75 (2379)

Mount Lorette (Ron) There was light wind all day with altocumulus cloud cover and temperatures that ranged from -14C to 3C. The cloud cover gave an excellent backdrop to migrating birds that were, in the main, conspicuously absent, with only 10 migrants seen between 1351 and 1630. 12 hours (286.9) BAEA 3 (63), NOGO 1 (3), UA 1 (2) GOEA 4 (1054), UU 1 (2) TOTAL 10 (1131)
