October 11 [Day 46] The upslope conditions of the last couple of days continued with light winds from the E–ENE until 1880 when they backed to SSE. The temperature rose to -3C from a low of -8C, and 80-90% stratocumulus and cumulus cloud gave way to diminishing amounts of cumulus after 1300 culminating in a cloudless sky at 1900. The Livingstone Range to the north was largely in cloud until 1150 when it cleared for the rest of the day, and apart from some light flurries in the early morning there was no precipitation. For the last two years October 11 has had the highest raptor movement of the season (514 and 518) but today saw only a modest trickle of birds and although it did pick up a bit after 1500 it was generally a disappointing day (although the afternoon sunshine was a pleasant change). The Golden Eagle seen at 1632 was the 4000th migrant raptor of the season, however. Four Golden Eagles soaring together at 1512 gave hope that a good movement was about to begin, but the last bird went that flew south at 1755 was only the 26th of the day. Three more dark adult “Harlan’s Hawks” moved south bringing the season’s total for the subspecies to 38, and a juvenile grey morph Gyrfalcon at 1554 was the first for the season (bird species #93) and the earliest yet recorded at the site. At Mount Lorette, Ron Dutcher had a similar day recording 30 Golden Eagles out of a total of 35 migrant raptors. Let’s hope that the west winds develop again soon! The most common migrant passerines were 55 American Robins, 23 Dark-eyed Juncos, 17 Grey-crowned Rosy-Finches, 22 White-winged Crossbills and 63 Pine Siskins, 60 of which passed in a single flock. 12 hours (528.91) SSHA 5 (1218), COHA 1 (222), NOGO 2 (105), RTHA 3 (189), GOEA 26 (1957), GYRF 1 (1) TOTAL 38 (4013)
