November 9 NO OBSERVATION Although the snow stopped early in the day, the ridges remained shrouded in cloud all day.

November 8 NO OBSERVATION Snow, with all ridges obscured all day .

November 7 [Day 46] (Bill Wilson) The temperature reached a high of 4C at 1200 and 1300 from a morning low of 0C, but fell to -1C at 1625 when steady snow terminated the count. Ground winds were SW 2-6 km/h until 1100 after which they varied between SE and SW 5-15 gusting to 28 km/h for the rest of the day, while ridge winds were moderate to strong SW creating snow plumes. Cloud cover was initially 70% altostratus and cumulus that quickly reduced to 10% at 0800 before gradually increasing to 100% stratus at 1300 which persisted for the rest of the day. The western ridges were clear until 1200 after which they gradually clouded-in, while the east was clear to 1530 after which they became shrouded from the north with the passage of a cold front and all ridges were obscured by 1625. Snow started at 1530 that became steady by 1625. The day started promisingly with the first Golden Eagle recorded at 0800 which was the first of 9 birds (4 Bald and 5 Golden Eagles) seen between 0800 and 0900 This, however, proved to be the busiest hour of the day, although by 1200 25 migrant eagles had been counted. Movement slowed markedly in the afternoon and when the last Golden Eagle went south at 1535 the day's count was 31: 13 Bald Eagles (10a,1j,2u) and 18 Golden Eagles (10a,1j,2u). Very few other birds were seen including 2 American Dippers, 1 Pine Grosbeak and 2 Common Redpolls.

The further adventures of “Elaine” Elaine continues to move very slowly to the south and is presently about 10 km east of the central part of Canyon Ferry Lake.

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.

November 5 [Day 44] (George Halmazna) The temperature at 0800 was a remarkable 8.5C (it was ,an even more remarkable 12C at 0600!), rose to a high of 11C at 1200 and remained at 7C from 1500 to the end of the day. Ground winds were SW, 10-22 gusting 40 km/h in the morning, that gradually diminished in the afternoon and were 2-5 km/h after 1500, while ridge winds were strong SW in the morning, causing blowing snow, but they also diminished in the afternoon. Cloud cover was initially 100% altostratus and cumulus, which started to clear at 0900 and reduced to 20-30% lenticular cloud after 1600. Apart from the blowing snow, the ridges were clear all day. Raptor movement was again fairly strong and steady for the time of year, with 51 birds of 6 species mainly moving high from Mount Lorette or Skogan Pass to the Fisher Range between 0820 and the last bird at 1538, which also happened to be the 2,500^th Golden Eagle of the season. The highest single hourly count was 20 birds between 1200 and 1300, of which 14 were Golden Eagles. The flight comprised 7 adult Bald Eagles (equaling the highest count for the season), 1 late juvenile Northern Harrier (that hunted for a while by the river), 1 adult Northern Goshawk, 1 Rough-legged Hawk of indeterminate morph, 40 Golden Eagles (36a,2sa,2j) and the season's 6^th Peregrine Falcon (an unaged bird that flew fast over the eastern part of the valley at 1349). Other birds seen included 1 Golden-crowned Kinglet, 4 European Starlings, 20 Bohemian Waxwings, 2 Pine Grosbeaks, 31 White-winged Crossbills and 6 Common Redpolls. The single Snowshoe Hare seen had its all white winter pelage.

The further adventures of “Elaine” By the end of the day Elaine was still about 20 km east of Canyon Ferry Lake in the Big Belt Mountains east of Helena, southern Montana.

November 4 [Day 43] (Bill Wilson) [NOTE: change to Mountain Standard Time] The temperature at 0730 (MST) was -1C, reached a high of 9C at 1500 and essentially remained there for the rest of the day. Ground winds were WSW all day, 3-10 km/h to 1100, then gusting to 22 km/h to 1400 and finally 10-15 gusting 30 km/h for the rest of the day, while ridge winds were moderate to strong W all day creating snow plumes. Cloud cover was initially 50-80% altostratus and cumulus to1000, then 90-100% for the rest of the day. The ridges were essentially clear with only 5-10% of the western ridges obscured. The combined species count of 65 birds was the highest at the site since October 25, with most birds moving over the Fisher Range or over the eastern part of the Kananaskis Valley. The first migrants were Rough-legged Hawks at 0800 and 0842, and the first Golden Eagle was not seen until 0916. Subsequent movement was steady until 1614 when the last of the day's 7 Bald Eagles (4a,1sa,2j) went through. Surprisingly, this is the highest daily count for the species this season, which probably reflects generally above-average temperatures that has resulting in the persistence of open water (and food) to the north. The Golden Eagle count of 56 birds (44a,2sa,3j,7u) was also the highest since October 25. Other birds recorded included 1 exceptionally late American Pipit, 2 Pine Grosbeaks, 2 White-winged Crossbills and 8 Common Redpolls.

The further adventures of “Elaine” By the end of the day Elaine had moved to the ESE and was about 20 km east of Canyon Ferry Lake in the Big Belt Mountains east of Helena, southern Montana.

November 3 [Day 42] (Cliff Hansen) Unfortunately, the scheduled Principal Observer had a family medical emergency and was unable to go to the site. Fortunately Cliff was available,but was unable to arrive at the site until 1345 when the temperature was 5C. It rose to a high of 9.5C at 1500 and was still 6C at 1800. Ground winds were SW 5-10 gusting 25 km/h, and ridge winds were strong SW. Cloud cover was 100% cumulus, altostratus and cirrus becoming 60-70% cumulus, lenticular, altostratus, altocumulus and cirrus after 1700. The east ridges were clear, but the western ridges were 30-50% obscured after 1600. The first of the day's 15 Golden Eagles (10a,5u) recorded was not seen until 1451. This was over an hour after the start of the count, which suggests that the late start did not result in the loss of too much data. All the birds moved very high above the Fisher Range, the busiest hour was 7 birds between 1600 and 1700and the last bird was seen at 1752. Other birds were scarce and the only migrants seen was a flock of 7 American Robins flying to the south.
