March 6 [Day 15] The starting temperature was -2C but N winds gusting to 50 km/k, and stronger aloft, made it feel much cooler. North winds persisted until 1330 when they shifted to SW to WNW of similar strength. The high was 7C and apart from a cloudless period from 1000 to 1330 the cloud cover was a useful 20-80% altostratus and cirrus. The morning N winds delayed the first migrant until 1034 and migration remained slow and sporadic until 1500 after which 27 of the day’s 39 migrants moved. Unlike yesterday no birds moved after 1800 with the last migrant migrating high over the Livingstone Range at 1758. With the exception of a subadult Bald Eagle, all the migrant raptors were adults. One of the resident Golden Eagles was displaying at 0710 and the pair was conspicuous west of the ridge all day. At 1319 the pair was observed copulating on the same snow-free hill as yesterday, where the female spent a number of periods up to1 hour 19 minutes perched. At 1650 the male flew north carrying a 1.2 m stick which it dropped and quickly recovered once, possibly to augment an alternate nest. At 1830, the pair soared high over the ridge then glided west where female briefly visited the aerie for the only time today, before gliding south, presumably to roost. The only probable passerine migrants were 35 Grey-crowned Rosy-Finches flying north at 1635. 11.25 hours (152.3) BAEA 10 (90), NOGO 1 (5), GOEA 28 (128) TOTAL 39 (231)

Mount Lorette (Brian): 11 hours (66) GOEA 2 (16) TOTAL (19)
