November
6 [Day
45] (George Halmazna, assisted by Michael Woertman) The temperature
in the Hay Meadow was -4C at 0700 and rose to 4C at 1200, while at
the Lusk Creek site, to which the count was moved at 1300, the
temperature rose to 6C. Ground winds were light or calm for most of
the day, while ridge winds were probably moderate to strong SW-SSW.
Cloud cover was initially 40% altostratus, altocumulus and
lenticular, but quickly changed to 100% stratus around 1100 that
brought rain and then snow to the Hay Meadow site for the rest of the
day. The western ridges started to disappear in cloud at 1000 and by
noon all ridges were completely obscured. At 1300 the observers moved
to the Lusk Creek site where observing conditions were good until
1345 when snow began, and at 1430 the count was abandoned for the day
when everything was obscured in the rain and snow. A total of 18
migrant raptors (2 adult Bald Eagles, 1 adult Sharp-shinned Hawk, 3
adult Northern Goshawks, 1 Rough-legged Hawk and 11 Golden Eagles
(6a,1sa,1j)), were seen from the Hay Meadow site between 0752 and
1128. Lusk Creek, however, produced a spectacular concentrated
movement of 112 birds between 1300 and 1420, with 94 of the birds
(including 82 Golden Eagles) recorded between 1300 and 1400. The
flight seen at Lusk Creek comprised 18 Bald Eagles (12a,6j) and 94
Golden Eagles (86a,2j,6u), and the birds often moved immediately
overhead with up to 15 birds soaring together at one time. The
combined species total of 130 is the highest ever recorded in
November at Mount Lorette, as is the Golden Eagle count of 105. In
fact, this is only the third time that over 100 Golden Eagles have
been recorded here in November, the others being 106 on November 1,
2000 and 108 on November 8, 2009. The count of 20 Bald Eagles were also by
far the highest total of the season. A number of other bird species
were seen around the Hay Meadow before the weather deteriorated,
including 4 Common Mergansers, 1 Belted Kingfisher, 1 American
Three-toed Woodpecker, 5 Golden-crowned Kinglets, 15 Pine Grosbeaks,
6 Red Crossbills, 20 White-winged Crossbills, 272 Common Redpolls and
2 Pine Siskins.
