September 18 [Day 24] Light upslope winds (E-NE) prevailed all day and the morning started at 2C with all mountains clear and 70% cirrus cloud cover. By 0930 the Livingstone Range to the north was again enveloped in cloud which persisted to 1300 when it again cleared allowing the best movement of the day for the next 1.5 hours. At 1430 a broad band of precipitation could be seen to the north which effectively stopped migration, and at 1625 it reached the ridge bringing a mix of hail and rain that reduced the temperature to 1C from 5C by 1700. Early raptor movement was dominated by accipiters, but 3 Golden Eagles, one first subadult and 2 juveniles, moved between1334 and 1410 were almost certainly the 3 birds that failed to get lift yesterday. At 1422 the first Swainson’s Hawk of the season soared high to the north before finally disappearing into the base of a towering cumulus cloud. This is only the third record at the site of a species that is common just a few tens of kilometres to the east. Passerine movement was again dominated by kinglets, Yellow-rumped Warblers and robins and included a couple of Wilson’s Warblers. The Northern Pygmy-Owl which has now been around for the last 10 days sang repeated in the middle of the afternoon but could not be persuaded to show itself. 10 hours (263.86) NOHA 1 (41), SSHA 11 (379), COHA 3 (117), NOGO 1 (19), UA 2 (48), SWHA 1 (1), GOEA 3 (106) TOTAL 22 (891)
