October
30 [Day
39] (George Halmazna, assisted by Cliff Hansen) The initial
temperature was 5C which turned out to be the high for the day. By
1100 it had dropped to 3C and after briefly rising to 4C around 1500
it fell to 2C at 1600 when the count was abandoned for the day.
Ground winds were moderate SW in the morning becoming light in the
afternoon, and ridge winds were probably moderate to strong SW all
day. Cloud cover was 100% stratus all day bringing rain, the western
mountains were substantially obscured all day, and the eastern ridges
were up to 80% obscured before disappearing completely after 1400.
The observers moved to the Lusk Creek site around 1130 and briefly
found clearer conditions in which 3 adult Golden Eagles moved between
1217 and 1225, but conditions rapidly worsened generally and the
count was abandoned at 1600. There was some waterfowl movement
involving 85 Canada Geese in 3 flocks, 6 Mallards and 5 Common
Mergansers, and other birds seen included 1 American Robin, 12
Golden-crowned Kinglets, 20 Bohemian Waxwings, 40 European Starlings,
1 Song Sparrow, 1 White-throated Sparrow, 3 Dark-eyed Juncos and 5
White-winged Crossbills.

Elaine was just to the NW of Lake McDonald on the western flanks of
the Rocky Mountains in Glacier National Park, Montana.
October
29 [Day
38] (George Halmazna) The temperature at 0730 was 1C but fell to a
low of -2C at 1000 before it briefly reached a high of 7C at 1300;
from 1400 to the end of the day it remained at 6C. Ground winds were
initially calm or very light to 1000, then NE to 10 km/h to noon and
during the afternoon the wind was SW gusting up to 40 km/h at 1700,
and ridge winds were probably SW all day, light to moderate in the
morning and moderate to strong in the afternoon. Cloud cover was
80-90% stratus and cumulus to 1000, that cleared to 70% cumulus to
1300, thickened to 100% stratus from 1400 to 1600 that produced snow,
and was subsequently 70-80% stratus and cumulus to the end of the
day. The east ridges were clear to 1400 after which they were 30-90%
obscured for the rest of the day, while the west was 90% obscured
after 1400. The first Golden Eagle was seen at 0832 which seemed to
suggest that the day would produce a reasonable migration, but when
the last bird, a Bald Eagle, went through at 1318 the day's total was
only 7 birds: 1 juvenile Bald Eagle, 1 adult Northern Goshawk and 5
adult Golden Eagles. Four of the birds (1 Bald Eagle and 3 Golden
Eagles) were seen moving along the Fisher Range between 1300 and
1318. The only waterfowl moving south were a single flock of 35
Canada Geese, and other birds recorded included 1 Northern Shrike, 2
American Robins, 1 Varied Thrush, 2 American Pipits, 1 Song Sparrow,
3 Dark-eyed Juncos, 1 Pine Grosbeak, 4 White-crowned Sparrows, 1
Common Redpolls and 1 Pine Siskin.

October 28 [Day 37] (Bill Wilson) For the first time since October 20 the temperature at the site rose above freezing, with a high of 7C at 1400 from a morning low of -7.5C, and it remained at 5C at 1845. Ground winds were initially variable and light to 0930 and then WSW 5-15 gusting 33 km/h for the rest of the day, while ridge winds were moderate to strong W after 1100 resulting in snow pluming from the eastern ridges. Cloud cover was 50-100% cumulus all day and some very light snow blew in from the west between 1400 and 1600, and again at the end of the day. Apart from a couple of birds that flew south overhead all of the day’s 42 migrant raptors moved above the eastern part of the valley or along the Fisher Range between 0848 and 1809. Movement was fairly steady all day with a maximum hourly movement of only 7 birds between 1100 and 1200. The flight comprised 4 Bald Eagles (3a,1j), 1 unaged Northern Goshawk and 37 Golden Eagles (26a,1sa,4j,6u). other birds were scarce, but included 26 Canada Geese in a single flock, 3 Mallard, 1 Common Merganser and 1 American Robin.

October 27 [Day 36] (Joel Duncan) The temperature at 0900 was -10C, rose to a high of -4C between 1400 and 1800, and was -5C at 1830. Ground winds were light NE, occasionally gusting to 12km/h, while ridge winds were moderate SW probably becoming light after 1700. Initial cloud cover was 100% low stratus that obscured all the ridges, that began to break at 1000 and by 1100 had reduced to 30% cumulus, altostratus and cirrus. By 1500 cloud had again increased to 70% and by the end of the day was 90% altostratus, cumulus and cirrus. With the exception of the high peaks to the west, all ridges were clear by 1100. Despite apparent ideal migration conditions after 1100, the first migrant, a Golden Eagle, was not seen until 1311 and the last two of the day’s 22 Golden Eagles (13a,7j,2u) set down to roost on the Fisher Range ridge at 1803. All the eagles appeared at the northern end of the Fisher Range and moved to the SE either at ridge level or against the face of the mountain, and maximum hourly movement was 9 birds between 1500 and 1600. Other birds in the flight were 1 adult Bald Eagle, 1 light morph Rough-legged Hawk and the season’s 5th Peregrine Falcon, a juvenile bird. Waterfowl movement was confined to 42 Mallards in two flocks flying high to the south, and other birds included 1 Northern Shrike, 1 Song Sparrow, 1 White-throated Sparrow, 3 Dark-eyed Juncos and 18 Common Redpolls.

The further adventures of “Elaine” The cloud that has enveloped the Livingstone Range for about a week finally lifted and allowed Elaine to travel south along its entire length, crossing our Piitaistakis-South Livingstone site en route, before moving down to the Beaver Mines Lake area. She then crossed the Continental Divide into SE British Columbia and moved south into northern Montana on the Clark Range, roosting for the night just south of the international border.

October
26 [Day
35] (Terry Waters, assisted by Rod Smith) When Terry arrived at the
parking area at 0800 the temperature was -11C but low stratocumulus
cloud was obscuring all the ridges so he delayed the start of
observation to 1030, by which time the temperature had risen to -7C.
The day's temperature high was -5C between 1300 and 1500 and was -6C
when the count was abandoned at 1600. Ground winds were NW to 1300,
then N, generally light but gusting to 15 km/h late in the day, while
ridge winds were moderate WNW all day. By 1030 the stratocumulus
cloud cover had broken to 90% allowing brief sunny breaks, but by
1400 it was again 100%. The western ridges were 80-100% obscured all
day, but eastern ridges were more-or-less clear by 1030; at 1600,
however, they were again 100% obscured as the snow flurries that had
persisted all day turned to steady heavy snow. The observers'
persistence was rewarded by 7 migrant raptors – 1 adult Northern
Goshawk and 6 Golden Eagles (5a,1u) - that were seen between 1200
and 1450. All birds moved singly with low flapping flight, either
overhead above the centre of the valley or against the face of the
Fisher range. There was some migration of waterbirds with 10 Common
Loons (8+2), 16 Canada Geese, 2 Mallards and 1 Common Merganser
flying to the south, and other birds seen included 4 Golden-crowned
Kinglets, 1 American Robin, 140 Bohemian Waxwings, 1 Fox Sparrow of
the race schistacea,
5 Grey-crowned Rosy-Finches, 16 Common Redpolls and 22 Pine Siskins.

October
25 [Day
34] (Cliff Hansen, assisted by Kevin Barker) The temperature rose to
a high of -4C at 1500 and 1600 from a morning low of -7C, and fell to
-6.5C at the end of the day. Ground winds were light NW-NE except
around 1700 when there were a couple of gusts to 15 km/h, and ridge
winds appeared to be light to moderate SW all day. Cloud cover was
100% altostratus and altocumulus to 1100 when it began to break up,
and reduced to 50% altostratus and cumulus at 1300 and finally to 5%
cumulus after 1700. All ridges were obscured until 1200 and were
variably obscured 50-70% to 1500 and only completely cleared after
1600. Not surprisingly, the first migrant Golden Eagles were not
seen until 1333, but movement was subsequently fairly steady. Maximum
movement was 43 birds (3 Bald and 40 Golden Eagles) between 1600 and
1700, but between 1720 and 1812 no birds were seen and it appeared
that the day's movement was over. A further15 Golden Eagles, however,
moved late and the last 3 Golden Eagles disappeared in the rapidly
fading light at 1840. Before 1400 birds moved low beneath the cloud
cover on Skogan Pass then crossed the valley to the face of the
Fisher Range, but after 1400 birds appeared from behind the Fisher
Range ridge before moving to the SE in the face of the range or at
ridge level. The day's count of 127 birds comprised 3 adult Bald
Eagles, 2 adult Sharp-shinned Hawks, 2 light morph Rough-legged Hawks
and 119 Golden Eagles (93a,2sa,24u), which is the thirds highest
total for the season. The fading light late in the flight made aging
of the last birds impossible. Waterfowl migrants were a flock of 90
Canada Geese that flew overhead at 1435, and flocks of 5 and 50
Common Mergansers, while other birds included 1 American Robin, 1
European Starling, 1 Song Sparrow, 1 White-throated Sparrow, 1 female
Rusty Blackbird and the season's first Pine Grosbeak.

The further
adventures of “Elaine” Today
Elaine only moved about 20 km to the SE and spent the night in the
vicinity of Mount Burke at the northern end of the Livingstone Range,
which was again shrouded in cloud all day.
Wednesday, October 24, 2012
October 24 [Day
33] (Terry Waters, assisted by Rod Smith) All ridges were obscured
for most of the morning and observation did not start until 1115 when
the temperature was -11C. It warmed to -5C at 1400 and stayed there
until the end of the day, but it felt colder as initial light SW
ground winds turned to NW 5-10 gusting 15 km/h at 1400 and remained
there. Ridge winds were probably mainly light NW all day. Cloud cover
at 1115 was 80% cirrus and cumulus that reduced to 50% at 1500 before
thickening to 80-90% cirrus, cumulus and altocumulus by the end of
the day. The eastern ridges were clear until 1600 after which they
were variably occluded 40-80% and were completely hidden after 1600,
while the western route was 50% obscured until 1700 and completely
obscured after. There was about 10 cm of fresh snow on the ground in
the morning, but none fell during the observation period. The first
migrants, 5 Golden Eagles, did not appear until 1215 but subsequently
movement was steady with hourly counts peaking at 24 birds between
1400 and 1500, and 25 birds between 1600 and 1700, and the last
Golden Eagle went through at 1745. Most birds moved low with flapping
flight from the face of Mount Lorette to the face of the Fisher
Range, although some birds also moved low from Skogan Pass down the
centre of the valley passing directly over the observers. The flight
of 100 raptors comprised 3 Bald Eagles (1a,2j), 2 Northern Goshawks
(1a,1j), 1 juvenile light morph calurus
Red-tailed Hawk, 1 light morph Rough-legged Hawk and 93 Golden Eagles
(65a,5sa,11j,12u). Elaine may well have been one of the group of 5
Golden Eagles that were seen at 1215. Other birds moving south were
40 Canada Geese, 3 Mallards and 1 Common Loon, and other birds seen
in the area included a flock of 85 Bohemian Waxwings, 6 Dark-eyed
Juncos and 12 White-winged Crossbills.

The further
adventures of “Elaine” By
the end of the day Elaine had moved SE from the Mount Lorette area
and was at the southern end of the Highwood Range near Mount Head.
The Livingstone Range to the south was shrouded in low cloud all day
so she probably could not go any farther because of the weather.
October 23 [Day
32] (George Halmazna) It snowed overnight leaving 5 cm of fresh snow
on the ground and light snow throughout the day added another 2 cm
before the count was abandoned for the day at 1430. The temperature
was initially -7C and reached a high of -5.5C at 1400, ground winds
were calm or light and cloud cover was 100% stratocumulus all day.
Parts of the ridges briefly became visible, but they were essentially
obscured all day. Not surprisingly no Golden Eagles were seen but 7
birds moved low to the south above the valley between 1012 and 1146:
2 Bald Eagles (1a,1j), 1 adult female Northern Harrier and 4 light
morph Rough-legged Hawks. Other birds seen included 2 Golden-crowned
Kinglets, 1 American Tree Sparrow and 1 Dark-eyed Junco, while ideal
snow-tracking conditions revealed the presence of 2 Canada Lynx in
the area.

The further
adventures of “Elaine” At
least one Golden Eagle was moving during the day as Elaine flew to
the SSE from SE Banff National Park and at the end of the day was
roosting somewhere in the Mount Lorette area!
October 22 [Day
31] (George Halmazna) The temperature at the beginning and end of the
day was -5C
and the high was -3.5C
at 1200. Ground winds were N all day, light to mid afternoon when
they gusted to 25 km/h around 1300, after which they became light
again, while ridge winds were probably NE light to moderate all day.
Cloud cover was initially 100% stratus that thinned to 50% stratus
and cumulus at 1200 before gradually thickening again to 100% stratus
after 1700. The ridges were obscured all day, although in the early
afternoon the lower two-thirds of the Fisher Range were visible.
Although conditions for migration were less than ideal there was a
reasonable raptor movement between 1146 and 1508. Until 1300 birds
flew low to the south below the clouds over the western side of the
Kananaskis Valley towards Evan-Thomas Creek, where some birds soared
to regain height. After 1300 birds moved overhead above the centre of
the valley, or above the eastern side of the valley towards The Wedge
at the northern end of the Opal Range. All birds used flapping flight
and movement became noticeably faster after 1300. The flight
comprised 2 juvenile Bald Eagles, 1 adult Northern Goshawk, 1 adult
dark morph calurus Red-tailed Hawk, a season-high total of 16
light morph Rough-legged Hawks and 33 Golden Eagles (26a,6sa,1j).
Other birds moving south included 52 Mallards and 5 first winter
Glaucous Gulls, and other birds recorded included 1 Northern Shrike,
6 Golden-crowned Kinglets, 2 American Robins, 1 Varied Thrush and 2
American Pipits.

By the end of the day Elaine had moved around 120 km from her last
location and was probably in the Fairholm Range near Lake Minnewanka,
north of Canmore.
Monday, October 22, 2012
October 21 [Day
30] (Bill Wilson, assisted by Cliff Hansen and Jim Davis) For the
first time this season the temperature failed to rise above freezing,
reaching a high of -2.5C at 1500 from a morning low of -5.5C, and
falling to 4C at the end of the day. Ground winds were very light NNW
to 1000, then NNW (or occasionally NNE) 5-10 with a maximum gust of
19 km/h until late afternoon when they dropped to 2-5 km/h. Ridge
winds were moderate-strong SSW all day, becoming lighter in the late
afternoon. There was 4 cm of fresh snow on the ground first thing in
the morning, and cloud cover was 100% stratus that obscured all the
ridges until 1000. Clearing began after 1000 and for the rest of the
day cloud cover was 20-80% cumulus with occasional development of
cirrus and stratus giving generally good observing conditions. The
western ridges remained 70-100% obscured for the rest of the day, the
eastern route was completely clear at 1300 and 1400, but was variably
obscured 30-90% for the rest of the day. Very light snow flurries
were experienced in the mid to late afternoon. Despite these less
than ideal conditions there was a reasonable raptor movement of 102
birds of 7 species, including 86 Golden Eagles (67a,1sa,9j,9u) all of
which moved high near the top of the Fisher Range, or above the ridge
after soaring, especially between 1400 and 1700. The first bird of
the day was a Rough-legged Hawk that flapped low to the south before
perching at 0802, but the first Golden Eagle did not go through until
1132. Movement gradually increased with 71 of the day's 102 birds
being recorded between 1400 and 1700. The last bird of the day was a
Golden Eagle at 1736 that happened to be the 2000th
bird of the season. Other raptors recorded were 1 juvenile Bald
Eagle, 1 unaged Sharp-shinned Hawk, 1 adult Northern Goshawk, 1 adult
dark morph harlani
Red-tailed Hawk and a season-high 11 Rough-legged Hawks (7 light and
4 dark morphs). The raptor of the day, however, was an juvenile light
morph Broad-winged Hawk that moved through between 1600 and 1700,
which was the first record of the species this season. The sudden
onset of winter conditions also resulted in a spectacular southern
movement of waterfowl including 129 Canada Geese (largest flock 65),
55 Greater White-fronted Geese in a single flock (a species that is
very rare in the mountains), 235 Mallards (largest flock 160) and 110
Common Mergansers (largest flock 60). A total of 26 American Robins
also flew to the south in low numbers throughout the day. On a day of
remarkable bird sightings, however, the strangest was a
Black-and-White Warbler that was both a new species for the area and
very late. It was found by Jim Davis as it foraged for food on the
ground in willow shrub fringing the Hay Meadow, and was subsequently
photographed by Cliff. With cold and snowy conditions forecast for
the next couple of days its survival prospects are probably not high.

The further
adventures of “Elaine”
Today Elaine moved just under 100 km to the SE and is presently just
outside Banff National park about 60 km NE of Lake Louise. She
appears to be presently moving though the foothills, probably because
of low cloud in the Front Ranges to the west.

October 20 NO
OBSERVATION (Joel Duncan) Joel drove west on Highway 1 early in the
morning, but at Scott Lake Hill found, having already passed several
cars in the roadside ditch, that the whiteout driving conditions were
too dangerous to proceed. He waited an hour at the hill, but decided
that conditions were not going to improve.
The further
adventures of “Elaine” On
October 20 Elaine was east of the north end of Abraham Lake reservoir
(north Saskatchewan River Valley), probably on or near the Ram Range
of the Front Range system, at about the latitude of Red Deer. It is
likely that the onset of winter weather conditions will impede her
southward progress for the next few days.

October 19 [Day
29] (Terry Waters) Temperatures were remarkably steady all day
ranging from 9C at the beginning and end of the day to a high of 11C
at 1000. Ground winds were SW 50-60 km/h to noon, 10-20 gusting 40
km/h to 1500, and then 20 gusting 50 km/h to the end of the day,
while ridge winds were strong SW all day. Initial cloud cover was 80%
altostratus, cumulus and altocumulus that reached 100% at 1300 and
then gradually reduced to 60% at the end of the day. The western
ridges were obscured all day, the eastern route was up to 10%
obscured between 1200 and 1600, and there were frequent rain showers
all day. The first Golden Eagle was seen at 0910 but by noon only 2
birds had been seen. The afternoon, however, saw a fairly steady
stream of birds gliding high and fast above the Fisher Range with a
movement of 72 birds peaking between 1300 and 1400 when 24 birds
passed, of which 22 were Golden Eagles. The flight comprised 2
juvenile Bald Eagles, 3 Rough-legged Hawks (1 light and 2 dark
morphs), 66 Golden Eagles (49a,4sa,2j,11u) and 1 adult Peregrine
Falcon. Other birds were scarce but included 6 Bohemian Waxwings, 12
Grey-crowned Rosy-Finches, and 50 Pine Siskins.

October 18 [Day
28] (Cliff Hansen, assisted by Chris Hunt) The temperature was 1.5C
at 0830, rose to a high of 11C at 1600 and was still 7C at 1800.
Ground winds were variable and generally light to 1200, after which
they were SW 2-12 gusting 15-25 km/h for the rest of the day, and
ridge winds were moderate to strong SW all day. Cloud cover was 30%
cumulus and lenticular to 1200 after which an arch developed over the
Fisher Range that had moved east of the range by 1600 and replaced by
90% cumulus, altostratus and cirrus until the end of the day.
Observing conditions were again good but aging of high flying birds
was difficult in the morning and late afternoon. The dynamic was
similar to that of yesterday with all birds using the eastern route,
the eagles gliding very high above the Fisher Range when the arch was
present, but otherwise they moved in the face of the ridge or just
above it. Movement was again steady all day between 0950 and 1845,
and the highest hourly count was 9 Golden Eagles between 1600 and
1700. The flight of 48 birds comprised 1 unaged Bald Eagle, 2
Sharp-shinned Hawks (1a,1u) and 45 Golden Eagles (33a,1sa,11u). As is
usual on windy days at the site other birds were relatively scarce,
but included 5 adult California Gulls flying low to the south over
the meadow, 1 Northern Shrike, 1 American Robin, 1 Song Sparrow and
35 White-winged Crossbills.

October 17 [Day
27] (Terry Waters, assisted by Rod Smith) The temperature again
reached a high of 7C at 1600 from a morning low of 0C and by 1800 the
temperature had dropped to 1C. Ground winds were SW 10-20 km/h all
day and ridge winds were strong SW all day. Cloud cover was 10-20%
altocumulus until 1400 (except around 1000 when it briefly increased
to 40%) after which it gradually diminished to 0% at the end of the
day. Despite the lack of cloud cover observing conditions were good
until late afternoon. A total of 69 migrant raptors were seen between
0920 and 1745 comprising 2 adult Bald Eagles, 1 adult Sharp-shinned
Hawk 1 adult Northern Goshawk, 2 small unidentified accipiters and 63
Golden Eagles (49a,4sa,10u). Movement was steady throughout the day
and peaked at 14 birds between 1400 and 1500. All birds used the
eastern route with some birds moving high and fast from Mount Lorette
to the Fisher Range, while others appeared at the northern end of the
Fisher Range, kited high and glided high to the SE above the ridge.
Amongst other birds seen were two surprisingly late flocks of Cedar
Waxwings totaling 49 birds flying to the south. Also flying south
were a total of 6 Common Loons (4 single birds and 2 together), and 8
American Robins, 18 Dark-eyed Juncos and 16 Grey-crowned Rosy
Finches.

northern end of Rocky Mountain Provincial Park near Highway 97. She
is now on the “Eagle Highway” and, if the weather holds, should
make rapid progress south in the next couple of days.
Wednesday, October 17, 2012
October 16 [Day 26] (George Halmazna) The temperature
was 7C at 1730, which equaled the high for the day, the low was 4C at 0900 before
it again climbed to 7C at 1100 and was 5C at 1730. Ground winds were SSW calm
to light with occasional gusts to 15 km/h, and ridge winds appeared to be
moderate-strong SSW-W changing to NW after 1100 and calm after 1500. It had
rained until around 0600 and cloud cover was initially 90% stratus and cumulus that
continued to produce rain and flurries to the west, and cloud cover remained
thick all day. The ridges were 100% obscured until 1100 after which they mainly
cleared. The first raptor seen was a probable resident adult Northern Goshawk that
perched and called east of the river at 0823 and the first migrant was a Golden
Eagle at 0907. When 29 Golden Eagles were recorded between 1000 and 1100 it
looked that another big day was in prospect, but the rest of the day only
produced a further 21 birds and the last Golden Eagle was seen at 1318. Birds moved
over the eastern part of the valley as the Fisher Range ridge was still
obscured, and lift appeared to be poor. All the 57 migrants seen were Golden
Eagles and comprised 45 adults, 2 subadults, 9 juveniles and 1 unaged bird.
Other birds seen included 4 Ruby-crowned Kinglets, 2 American Pipits, 25
Bohemian Waxwings, 2 Dark-eyed Juncos, 9 White-winged Crossbills and 42 Pine
Siskins. It appears that the Black Bear that has been in the same place on the
lower slopes of the northern end of the Fisher Range for about a month, has an
injured right front paw: it generally moves very slowly with a heavy limp. George
had previously witnessed a “bluff’ confrontation between the bear and a Grizzly
Bear in the same area, and speculates that a subsequent, unobserved, clash may
have resulted in the injured paw.

October 15 [Day 25] (George Halmazna) The temperature
at 0700 was 11C but the day’s low was at 1000 when it dropped to 10C before
climbing to a high of 14C at 1400: it was still 11C at 1900. Ground winds were
initially calm or light S, but SW winds quickly became established that gusted
to 40 km/h in mid-afternoon but became light at the end of the day. Ridge winds
were probably SW moderate to strong throughout the day. Cloud cover was initially
90% cumulus, stratus and cirrus that diminished to 20% cumulus at 1500 and 1600
before again increasing to 80% cumulus and stratus at the end of the day. The
ridges were generally clear all day, although the west saw flurries between
0800 and 1300 that obscured peaks from time to time. Migration conditions were
good with 344 raptors moving mainly above the Fisher Range between 0730 and
1845. Maximum movement was 68 between 0900 and 1000 and with the exception of
1200-1300 (15 birds) each subsequent hour to 1900 yielded between 20 and 39
birds. The flight comprised 3 adult Bald Eagles, 3 Sharp-shinned Hawks (1j,2u),
1 adult Cooper’s Hawk, 1 adult Northern Goshawk, 1 dark morph Rough-legged
Hawk, 334 Golden Eagles (257a,1sa,44j,32u), the second highest count of the
season, and 1 adult Prairie Falcon. Other birds included 1 Pacific Loon flying
south at 1133 and 2 single Common Loons that flew south at 0855 and 1204, 11
Ruby-crowned Kinglets, 1 Varied Thrush, 6 American Pipits, 124 White-winged Crossbills
and 15 Pine Siskins. The large Black Bear was still on the lower slopes of the
northern end of the Fisher Range.
Piitaistakis-South Livingstone (Denise
Cocciolone-Amatto, Shirley Enszol) Observations were made from the upper Frank
Slide site between 1350 and 1600. It was still mild but cooler than the
previous two days at the site and ridge winds appeared to be W strong. Raptors moved
very high to the south on the windward side of the Piitaistakis Ridge until
1525 after which the birds kited well to the west of the ridge and moved high
to the south above the valley. The flight of 43 birds comprised 1 Sharp-shinned
Hawk, 34 Golden Eagles (27a,2sa,5j) and 8 unidentified small raptors that were
probably either Sharp-shinned or Cooper’s Hawks, but their height and the
turbulent conditions aloft precluded accurate identification.
The further adventures of “Elaine” By the end of October 15 Elaine had
travelled another 70 km to the SE and was almost at the Yukon/BC border near
the Crow River. She should move south into NE British Columbia tomorrow.

October 14 [Day 24] (Bill Wilson) The temperature at
0800 was 8C, reached a high of 14C between 1400 and 1600 and was still 12.5C at
1930. Ground winds were initially calm to light SSE but after 0900 they were
WSW 10-20 gusting to over 50 km/h for the rest of the day, while ridge winds
were moderate to strong WSW all day. Cloud cover was mainly cumulus and
altostratus all day, 100% to 1300 after which it varied between 60% (at 1700)
to 100%. The western route was 5-10% obscured in the morning and again at the
end of the day, but the eastern route was clear all day. Despite this most of
the eagles seen flew high over the eastern part of the Kananaskis Valley or
overhead, and probably came from Mount Lorette although none were seen there.
In the afternoon many eagles flew very high above the lowest cumulus cloud
layer and could only be seen when there were breaks in the cloud. It is
probable that many birds passed unobserved when such breaks were not present. The first Golden Eagle occurred at 0857 but by
noon only 9 migrants (2 Bald and 7 Golden Eagles) had been seen. Between 1200
and 1300 30 of the day’s 86 birds were recorded (29 Golden eagles and 1
goshawk), but for the rest of the afternoon movement was only between 5 and 11
birds per hour and the last Golden eagle went south at 1825. The flight
comprised 2 adult Bald Eagles, 1 adult Northern Goshawk and 83 Golden Eagles
(55a,1j,27u), the high number of unaged birds again resulting from the poor observing
conditions.

The further adventures of “Elaine” On October 14 Elaine had continued her
journey to the SE and was about 50 km north of the Yukon/BC border just east of
126oW. In the next couple of days she should arrive at the northern
end of the Canadian Rocky Mountain Front Ranges after which, if weather conditions
remain good, she could be passing by our Mount Lorette site a couple of days
later.
October 13 [Day 23] (Terry waters, assisted by Rod
Smith and Jim Davis) Strong down-slope winds resulted in a temperature of 8C at
0800, that rose to a high of 14C at 1400 and that was still 9C at 1830. Ground
winds were SW all day, 10-15 gusting above 20 km/h, and ridge winds were
moderate to strong SW all day. Cloud cover was initially 90% altocumulus and
cumulus that increased to 100% at 1100 before diminishing to 40-50% altocumulus,
stratocumulus and cirrus throughout the afternoon. Occasional brief, very light
rain showers occurred throughout the day. Raptor movement was similar to that
of yesterday with birds gliding very high and fast from Mount Lorette to the northern
end of the Fisher Range, although 4 birds were seen on the western route, and a
couple of birds passed high overhead. Maximum movement was 16 Golden Eagles seen
between 1500 and 1600, and otherwise birds moved fairly steadily between 0910
and 1810 with the exception of a lull between 1200 and 1400. The flight of 55
birds comprised 2 dark morph Rough-legged Hawks, 52 Golden Eagles (44a,
2sa,1j,7u) and the season’s first Prairie Falcon (probably a juvenile) that was
seen hunting low over the Hay Meadow. Other birds recorded were 11 loons or
large grebes flying vary high to the south over the northern end of the Fisher
Range at 1016, 55 American Robins, 4 American Pipits and 8 Red Crossbills,
while the Black Bear was seen yet again in its usual place on the lower slopes
of the northern end of the Fisher Range where it has been seen most days since
September 24.

Canmore Eagle
Festival (Peter Sherrington assisted by Chris Hunt and Kevin Barker) Weather
conditions were generally similar to those at Mount Lorette and 80-100%
altocumulus and cumulus cloud cover provided excellent viewing conditions in
the immediate area. Unfortunately, low cloud could be seen to the NW enveloping
the Fairholm Range for periods throughout the day, and this, together with strong
SW-W ridge winds probably diverted most birds to more easterly ridges where
they could not be seen from the Bow Valley bottom site in Canmore. A total of only
11 Golden Eagles (9a,1sa,1u) were recorded between 1031 and 1637 with most
birds appearing low on the north ridge of Mount Lady McDonald before kiting
high and gliding high and fast to Grotto Mountain. From there the birds would
have crossed the Bow Valley to Pigeon Mountain in the Kananaskis Range and
thence on to Mount McGillivray and Mount Lorette, where, joined by birds moving
from the more easterly ridges of the Fairholm Range, they would be picked up by
the observers at the Mount Lorette site. Despite the low numbers of eagles,
many of the hundreds of visitors to the Festival viewed the birds. The
highlight of the day, however, was the unveiling of a 10 metre high sculpture outside
the soon to be completed Canmore Elevation Place Plaza community centre, by New
Brunswick artist Peter Powning. The upper portion of this sculpture is a beautiful
stainless steel spire with silhouettes of soaring Golden Eagles together with
ravens cut through the steel, to celebrate the annual eagle migrations that fly
by the town. A picture of the sculpture can be seen at www.canmore.ca/festivalofeagles.
Piitaistakis-South Livingstone (Denise
Cocciolone-Amatto, Penny Takahashi, Cenney Yau and Wendy Dercole) Observations
were made from the upper Frank Slide site between 1145 and 1500 where the
temperature ranged from 8C to 10C and ground winds were light but ridge winds
were probably W moderate to strong. The 3.25 hours spent at the site yielded 69
migrant raptors: 11 Sharp-shinned Hawks, 2 Cooper’s Hawks, 54 Golden Eagles
(50a,1sa,3j) and 1 Merlin.
October 12 [Day 22] (Joel Duncan) The temperature was
-1C at 0815, rose to a high of 12.5C at 1500 and was 10C at 1915. Ground winds
were initially light SW, but after 1100 increased to 20 gusting 50 km/h for the
rest of the day, while ridge winds were strong W-SW all day. Initial cloud
cover was 80% altocumulus, altostratus and cirrus that gradually reduced to 20%
altocumulus at 1500 before slowly increasing to 40% altocumulus and cirrus at
1900. Observing conditions were good in the afternoon, although the height of
the birds often made aging impossible. A total of 26 migrant raptors were seen
between 0839 and 1849, with birds travelling the normal route from Mount
Lorette to the Fisher Range until the wind velocity increased, after which the
birds appeared behind the northern end of the Fisher Range and kited very high before gliding to the SE well
above the ridge. Peak movement was 8 birds between 1700 and 1800, but for most
of the day movement was light and sporadic. The flight comprised 1 adult Bald
Eagle, 1 dark morph Rough-legged Hawk, 1 unidentified Buteo, 26 Golden eagles (6a,1sa,9j,11u) and 1 undifferentiated
eagle. Other birds recorded included 1 Common Loon flying high to the south, 1
Varied Thrush singing early in the morning, 1 American Robin, 1 Yellow-rumped
Warbler, 1 Song Sparrow, a high-flying flock of 60 Grey-crowned Rosy-Finches
and 20 White-winged Crossbills.

October
11 [Day
21] (Cliff Hansen, assisted by Kevin Barker) As on October 8 a
disturbance associated with the passage of a cold front proved to be
short and not very sharp with only a skiff of fresh snow on the
ground this morning. The temperature at 0900 was -1C that gradually
rose to a high of 12C at 1600 before quickly falling to 2C at 1900.
Ground winds were variable all day, generally light but occasionally
gusting to 15 km/h between 1300 and 1600, and after 1900 it was calm,
while ridge winds were probably moderate SSW for most of the day.
Cloud cover was initially 80% altocumulus that turned to 60-70%
cumulus and lenticular until an altostratus arch formed between 1600
and 1900 which occupied 50% of the sky. The first migrant raptor was
the day's only Rough-legged Hawk (a dark morph) at 1105, and the
first Golden Eagle appeared at 1130. The movement was remarkably
steady all day with passage during the 7 hourly periods between 1200
and 1858 varying between 8 and 14 birds with peak movement between
1400 and 1500 (1 Northern Goshawk and 13 Golden Eagles). Some birds
were first seen over Mount Lorette, but most were sighted approaching
the lower half of the northern Fisher Range, after which most moved
slowly to the SE just below or just above the ridge. The flight of 84
birds comprised 5 Bald Eagles (4a,1j), 6 Sharp-shinned Hawks (3a,3u),
1 adult Northern Goshawk, 1 dark morph Rough-legged Hawk and 71
Golden Eagles (49a,1sa,4j,17u). The Black Bear remained on the lower
slopes of the northern end of the Fisher Range, and other birds seen
included a male Blue-winged Teal on the river, 1 Wilson's Snipe, 5
American Pipits, 2 American Tree Sparrows and the first Harris's
Sparrow of the season.

Piitaistakis-South
Livingstone (Denise Cocciolone-Amatto, Merilyn Liddell) Denise and Merilyn observed
from the upper Frank Slide site between 1535 and 1715. The temperature was very
mild for the time of year, winds were moderate to strong W-SW and observation
conditions were good with intermittent sunshine and banks of grey cloud behind the
ridge to the east, Raptor movement was strong and the 2.83 hours yielded 151
migrant raptors that generally kited and glided very high to the south on the
windward side of the Piitaistakis Ridge. The flight comprised 1 Bald Eagle, 1
Northern Harrier, 1 Sharp-shinned Hawk, 1 Northern Goshawk and 147 Golden
Eagles (133a,1sa,13j). The height and speed of the birds made age
identification difficult and several Golden Eagles assessed as being adult could
well have been immature: it is also probable that many accipiters were missed
because of the height of the movement.
The
further adventures of “Elaine” By
October 9 Elaine had made a slow progress to the south and was still
in central Yukon north of the Nadaleen Range in the area east of
Rusty Mountain.

10 NO
OBSERVATION (Terry Waters) At 0815 it was 0C, raining and everything
was obscured. At 1200 the rain turned to snow and the temperature
fell to -1C, and with no prospect of the weather improving Terry left
the area at 1400.
October
9 [Day
20] (George Halmazna) Yesterday's disturbance was short-lived and
today the ridges an peaks remained completely clear all day. The
temperature at 0710 was -1.5C, rose to a high of 11C at 1600 and was
4C at 1930. Ground winds were light SW becoming S in the afternoon,
with a maximum gust of 15 km/h at 1300, and ridge winds were moderate
SW to 1300 after which persistent blowing snow indicated moderate to
strong velocities. Cloud cover was initially 100% altocumulus to 0900
after which it gradually cleared after 1000 to 5% cumulus. Raptors
started moving early with the first Northern Goshawk seen at 0730 and
the first Golden Eagle at 0822 and by the time the last Golden Eagle
was logged at 1920 a season-high total of 441 raptors had been
counted of which a season-high total of 428 were Golden Eagles
(315a,19a,89j,5u). The birds moved steadily from Mount Lorette to the
face of the northern end of the Fisher Range which, combined with
ideal light conditions, made the aging of the birds easy. Maximum
passage of Golden Eagles was 99 between 1700 and 1800, and the total
of 428 is the eighth highest fall count for the species at the site.
It is interesting to note that on October 8 last year 556 birds were
counted at the site (the second highest ever). Other raptors seen
were 2 adult Bald Eagles, 2 Sharp-shinned Hawks (1a,1j), 2 Northern
Goshawks (1a,1u), 6 Rough-legged Hawks (2 light, 3 “intermediate”
and 1 dark morph) and the season's first Gyrfalcon, a grey morph that
was seen at 1218. Golden Eagles were also moving through the high
foothills to the east as Michael Woertman observed 42 birds (39a,3j)
in 2 hours (1300-1500), along with 2 adult Bald Eagles, 3u
Sharp-shinned Hawks and 1 Merlin. Non-raptor species noted at Lorette
included 8 Golden crowned Kinglets, 15 American Pipits and 3 Brewer's
Blackbirds; a single Mourning Cloak butterfly was on the wing, and
the Black Bear on the lower slopes of the northern end of the Fisher
Range had a ringside seat for the best eagle migration of the year.

8 [Day
19] (George Halmazna) A cold front moved through in the early morning
and a high temperature of 4C at 0710 fell to 1C at 1300 and stayed
there all day. Ground winds were calm or light all day, initially NNW
to 1000 and subsequently NNE for the rest of the day. Cloud cover was
100% low stratus all day and although the lower slopes were visible
from time to time all peaks and ridges were completely obscured. Rain
and drizzle in the morning changed to snow in the afternoon as the
temperature dropped. Not surprisingly only three migrant raptors were
seen, and all moved low to the south above the centre of the valley
between 1052 and 1532. The birds were 1 adult Sharp-shinned Hawk, 1
adult Northern Goshawk and 1 adult dark morph calurus
Red-tailed Hawk. The bird highlight, however, was an adult Glaucous
Gull that flew low overhead to the south at 1430, and a juvenile
Northern Shrike was the first for the season. Other birds recorded
included 1 Ruby-crowned Kinglet, 6 American Robins, 1 American Pipit,
2 Yellow-rumped Warblers, 2 rather late Brewer's Blackbirds and 3
White-winged Crossbills. The Black Bear was seen again on the lower
slopes of the northern end of the Fisher Range.

7 [Day
18] (Bill Wilson) The temperature reached a high of 14.5C at 1500 and
1600 from a low of -6.5C and was 10C at 1920. Ground winds were
initially SW 0-2 km/h increasing briefly to 3-10 gusting 21 km/h
around 1300 before becoming very light again for the afternoon, while
ridge winds were light SW in the morning becoming light to moderate
in the afternoon. An initial cloud cover of 5% cirrus increased to
80-100% altostratus to 1300, after which there was 80-100% cumulus,
with the exception of 1500 when it briefly dropped to 30%. Observing
conditions were good and the day produced a season high combined
species count of 137 birds that included season high counts of 6
Rough-legged Hawks (4 light, 1 dark and 1 unknown morph) and 116
Golden Eagles (64a,6sa,28j 18u).
Birds
moved between 0812 and 1855 appearing low at the northern end of the
Fisher Range and moving in the face of the range in the morning, and
just above the ridge in the afternoon. Lift appeared to be poor and
there was only a moderate amount of soaring. Maximum movement
occurred between 1400 and 1500 when 39 birds passed, 33 of which were
Golden Eagles. The rest of the flight comprised 4 Bald Eagles
(2a,2j), 4 unaged Sharp-shinned Hawks, 3 Northern Goshawks (2a,1u),
and 4 calurus
Red-tailed Hawks (1adult and 1 juvenile light morph birds, and 2 dark
morph juveniles). Two Rusty Blackbirds were a seasonal first record,
and other birds seen included 2 Common Loons flying high to the
south, flocks of 29 and 16 Canada Geese also flying south, 1
Yellow-rumped Warbler, 1 American Tree Sparrow and 1 slate-coloured
morph Dark-eyed Junco of the race hyemalis.

Livingstone (Gerald
Romanchuk and Steve Knight) Gerald and Steve, who had been with me on

(1420-1850) counted a total of 187 migrant raptors. The flight
comprised 3 Bald Eagles, 1 Northern Harrier, 8 Sharp-shinned Hawks, 1
Cooper's Hawk, 3 Northern Goshawks, 3 Red-tailed Hawks and 168 Golden
Eagles.
October 6 [Day
17] (Joel Duncan) It was a much warmer day with a temperature of 1C
at 0900 that rose to a high of 12.5C at 1600 and it was still 11C at
1930. Ground winds were light SW all day, occasionally calm but
averaging 2-6 km/h with a gust of 13 km/h at 1600, and ridge winds
were estimated as moderate west all day. The high wind flow, however,
still appeared to be from the north. Initial cloud cover was 100%
stratus with both the eastern and western ridges 80% obscured, but by
1100 all ridges were clear with an 80% altocumulus cloud cover that
steadily diminished to 5% by 1600. The first migrant, an unaged
Golden Eagle, was not seen until 1049, but there was a subsequent
steady flow of birds until 1910, with 28 of the day's 83 raptors
occurring between 1300 and 1400. The flight comprised 2 adult Bald
Eagles, 3 unaged Sharp-shinned Hawks, 2 unaged Cooper's Hawks, 2
light morph calurus Red-tailed Hawks (1a,1j), 73 Golden Eagles
(31a,9sa,16j,17u) and 1 probable columbarius Merlin of unknown
age/sex. With the exception of a Bald Eagle seen to the west, all
migrants moved high from Mount Lorette to the Fisher Range where most
birds gliding high above the ridge indicating good wind-lift
conditions. A good variety of non-raptor bird species was also noted
including the first Brown Creeper (1) and American Tree Sparrows (3)
of the season, 12 Golden-crowned and 2 Ruby-crowned Kinglets, 9
Yellow-rumped Warblers, 1 Wilson's Warbler, 16 White-winged
Crossbills, 8 Common Redpolls and 1 Pine Siskin. An unusual bird
behaviour was observed around noon when a male Belted Kingfisher that
was perched on a snag close to the site sallied out and caught and
ate a large moth in flight. As Joel was
preparing to leave the site at 1930 he became aware of a very large
male Moose feeding on Wolf Willows just 7 m away, and felt it prudent
to take a more circuitous route back to the parking area!

Livingstone (Peter
Sherrington, assisted by Phil Nicholas, Gerald Romanchuk and Steve
Knight) The general public were invited to join me on the ridge today
and 22 visitors and myself set off up the climb at 0920. Before most
had reached the site, however, the clouds had lowered, bringing light
snow that reduced the temperature to -1C and completely obscured the
Livingstone Ridge to the north and the mountains to the west. The
wind was NW 5-10 gusting 25 km/h, and by 1225 when the snow ended and
the ridges began to clear all but 3 of the visitors had departed.
This was unfortunate as the temperature finally rose to 5C, the wind
diminished to 5-10 km/h and had moved to the W by late afternoon and
the cloud cover gradually diminished to 60-70% cumulus by the end of
the day. Those of us who were left, however, were treated to a
movement of 120 raptors of 5 species that occurred between 1315 and
1806, with a peak movement of 83 birds between 1500 and 1700. The
flight comprised 5 Bald Eagles (3a,2j), 7 Sharp-shinned Hawks
(6a,1u), 1 unaged Northern Goshawk, 6 Rough-legged Hawks (4 light,
1dark and 1 unknown morph), 1 unidentified Buteo and 100 Golden
Eagles (60a,11sa,18j,11u). The last hour of the flight was
particularly spectacular with birds moving low overhead or close to
the ridge in bright sunshine.

October 5 [Day
16] (Terry Waters, assisted by Rod Smith) Cloudless skies again
allowed the temperature to fall to -9C at 0815, but it reached a high
of 7C at 1600 before falling to -2C at the end of the day. Ground
winds were again light or calm, mainly NE becoming mainly SE after
1500, while ridge winds were probably light NNW for most of the day.
Scattered cumulus (5-10%) developed after 1100, and 20% cirrus after
1600 when it also became hazy, possibly because of smoke. The mainly
blue skies made observation difficult, although most birds soared
over Mount Lorette, quickly glided to the northern end of the Fisher
Range where they again soared before moving above the range to the
SE. The first raptor of the day was a juvenile Sharp-shinned Hawk
seen perched near the site at 0820, but the first moving bird was a
Golden Eagle at 1001 which, like the next three eagles, were the only
ones seen on the western route, soaring above Olympic Summit. The
movement of the day's 55 migrants was steady to 1500 followed by an
hiatus of 2 hours during which time only 3 birds occurred, then the
last 18 migrated between 1700 and 1817. The total comprised 3 adult
Bald Eagles, 1 juvenile Sharp-shinned Hawk, 1 adult Cooper's Hawk, 1
adult Northern Goshawk, 3 adult light morph calurus Red-tailed
Hawks, 45 Golden Eagles (29a,3sa,5j,8u) and the season's third
Peregrine Falcon (an adult). The day's last Golden Eagle was the
500th of the season. The Kananaskis River yielded 4
Mallards, a very late male Harlequin Duck, 2 Belted Kingfishers (1
male,1u) and 10 American Pipits, while other birds seen included 8
Golden-crowned Kinglets, 50 Pine Siskins, and a season-first 18
Common Redpolls in a single flock.

The further adventures of “Elaine” (Golden Eagle #78453)
Elaine,
an adult female Golden Eagle was captured and fitted with a
transmitter during the third week of October, 2010 by Rob Domenech
and his colleagues from the Raptor View Research Institute in
Montana. She spent the winter of 2010-11 in the Paradise Valley just
south of Livingstone, Montana and just north of Yellowstone National
Park. In the spring of 2011 she moved north, roosting for a night
(March 12) along the way on Bluff Mountain just west of our
Piitaistakis-South Livingstone site and the next day crossed Mount
Lorette on her way north. By early April she had reached the southern
flank of the Philip Smith Mountains of the Brooks Range in
northeastern Alaska where she spent the summer. Rob informed me that
it was not known if she bred there.
In the fall of 2011 Elaine started her southward journey on October 1
and had reached the Yukon by October 7, and then slowly moved to the
SE and on October 26 she was in the northernmost part of the Rocky
Mountains of NE BC. Four days later she was in northern Montana
having moved rapidly along the Front Range expressway, after which
she continued to make a a leisurely progress south before wintering
again in Paradise Valley in southern Montana.
In the spring of 2012 Elaine probably entered Alberta on March 8 and
after moving up the Front Ranges spent the night of March 10 in the
vicinity of Mount Lorette. She subsequently moved NW into NE British
Columbia then through the Yukon and NE Alaska and on April 7 she
reached her home range in the Philip Smith Mountains of the Brooks
Range where she presumably nested last year.
This Fall she started her fourth migration carrying a transmitter,
moving to the ESE around September 25 and by October 1 she was just
west of the Alaska-Yukon border. She has since moved SE into the
Yukon and on October 4 was near the Bonnet Plume River between the
eastern end of the Werneke Mountains and the Bonnet Plume Range of
the northern Selwyn Mountains.
You can follow her progress on a map on the seaturtle.org site via

colleagues from the Raptor View Research Institute in Montana for

October 4 [Day
15] (Cliff Hansen, assisted by Kevin Barker, Cliff Hansen and Michael
Woertman) The temperature was -4C at 0730 but fell under cloudless
skies to a season-low -9C at 0800, but rose to a high of 5C at 1600
at was 1.5C at the end of the day. Ground winds were variable all day
calm to light occasionally reaching 12 km/h, and ridge winds were
assessed as W light to moderate. It was cloudless to 1200 when
cumulus developed that reached 50% at 1600 before dwindling to 10% at
the end of the day. The first Golden Eagle was not seen until 1112
but subsequently there was a steady stream of raptors passing high
overhead from Mount McGillivray to Old Baldy until 1813 after which
the last 12 birds of the day moved on the usual route from Mount
Lorette to the north end of the Fisher Range, where the last bird of
the day, an unidentified Buteo, was seen at 1845. The flight
of 82 birds comprised 5 adult Bald Eagles, a season-high 15
Sharp-shinned Hawks (7a,2j,6u), 1 adult Cooper's Hawk, 1 unidentified
Accipiter, the season’s first Rough-legged Hawk (a light
morph), 1 unidentified Buteo and 58 Golden Eagles
(31a,4sa,9j,14u). Forty-five of the migrants were recorded before
1400 after which the pace slackened somewhat and only picked up again
between 1800 and 1845 when the last 12 birds passed. Without the eyes
of the three assistants scanning directly overhead the day's total
would probably have been somewhat lower! Non-raptor bird species
included a southbound flock of 14 female,juvenile Common Mergansers,
6 Clark's Nutcrackers flying to the south, 3 Golden-crowned and 2
Ruby-crowned Kinglets, only 4 American Robins, 3 Wilson's Warblers,
53 White-winged Crossbills and 30 Pine Siskins. An adult Black Bear
was also seen on the northern end of Hummingbird Plume Hill.

Livingstone (Raymond Toal,
Karola Michalsky, Denise Cocciolone-Amatto) Observations from the
upper Frank Slide site between 1400 and 1800 yielded 6 adult
migrating Golden Eagles.
October 3 [Day
14] (Terry Waters, assisted by Rod Smith) The ridges were obscured
all morning and as a result observation did not start until 1200,
when there was 2 cm of fresh snow on the ground. The temperature at
noon was -2C, rose to 4C at 1700 and had fallen back to 0C at 1830.
Ground winds were NE light (<5 km/h) all day, and ridge winds were
also probably light N-NW. Cloud cover was 100% stratus all morning,
then 80-90% stratocumulus for most of the afternoon that reduced to
50% stratocumulus and cumulus by the end of the day. The Fisher
Range finally cleared around 1600, but Mount Lorette remained
shrouded in cloud all day and the few migrants seen appeared to
originate from Heart Mountain to the north of Mount Lorette.
Intermittent snow flurries occurred throughout the afternoon. The
first migrant was an adult Northern Goshawk that flew to the south
above the valley at 1302, and the first Golden Eagle was a juvenile
that moved to the south against the face of the Fisher Range at 1355.
The day's other 2 Golden Eagles also moved low below the Fisher Range
ridge. The count was 1 adult Cooper's Hawk, 2 adult Northern
Goshawks, 3 Golden Eagles (1a,2j) and 1 adult Peregrine Falcon, and
the last bird of the day was seen at 1552. Other birds seen included
16 American Robins, 14 American Pipits feeding on gravel bars in the
river, and 45 Pine Siskins.

October 2 [Day
13] (George Halmazna) The temperature was -1C at 0700, but it felt
colder owing to the dampness from overnight rain (2330-0130). The
temperature rose to a high of 6C at 1000, soon after which a cold
front started making itself felt with the temperature falling to 4C.
Ground winds were initially calm or light NW, but changed at 1010 to
NE and by noon they were 15 gusting 30 km/h, and ridge winds probably
also reflected the same pattern. An initial cloud cover of 20%
cumulus gradually thickened to 100% stratus by 1300 which persisted
for the rest of the day. All ridges were clear until 1120 when cloud
started enveloping them from the north and by early afternoon all
were obscured, and rain with snow pellets developed around noon.
Before the weather changed, however, there was a steady movement of
Golden Eagles high to very high above the eastern side of the valley,
with 17 birds (10a,2j,5u) recorded between 0911 and 1114, 8 of which
occurred between 1000 and 1100. The only other raptor seen was an
adult Sharp-shinned Hawk. Other birds seen included 1 male Belted
Kingfisher, 2 Red-Breasted Nuthatches, 2 Ruby-crowned Kinglets, 37
American Robins, 1 Varied Thrush, 11 Yellow-rumped warblers, 4
Dark-eyed Juncos, 24 White-winged Crossbills and 25 Pine Siskins. The
Black Bear seen yesterday was still in the same place today.
9.67 hours (146.91)
SSHA 1 (20), GOEA 17 (394) TOTAL 18 (468)
October 1 [Day
12] (George Halmazna) The temperature at 0700 was a remarkable 12.5C
and rose to a high of 19C at 1600-1800. Ground winds were moderate to
strong SW all day, especially in the afternoon when winds were 30
km/h gusting above 80 km/h after 1600, and ridge winds were probably
also strong SW all day. Cloud cover was initially 80% cirrus reducing
to 40% altostratus at noon that increased to 80% at 1300 and thinned
again to 50% cumulus after 1700. Despite the high winds there was a
good eagle migration with 108 birds moving between 0835 and 1616,
which was the day's only Bald Eagle (an adult). A season high total
of 104 Golden Eagles (79a,1sa,10j,14u) moved steadily between 0835
and 1446 with all but 2 birds gliding high above the Fisher Range at
an estimated height of 300 m or more above the ridge. The only other
raptors seen were 3 Sharp-shinned Hawks (2a,1u). Other birds recorded
included 38 American Robins, 211 White-winged Crossbills and 68 Pine
Siskins, and a Black Bear was seen on the lower slopes of the north
end of the Fisher Range. Three Mourning Cloaks were the only
butterflies seen.

Piitaistakis-South
Livingstone (Raymond Toal, Denise Cocciolone-Amatto) Observations
were again made from the upper Frank Slide site between 1400 and
1815, where the W winds were strong and steady and the altostratus
and lenticular clouds made a spectacular backdrop for the migrating
raptors. The 4.25 hours produced 2 Ospreys, 1 Sharp-shinned Hawk, 1
Cooper's Hawk, 1 Northern Goshawk, and 38 Golden Eagles
(22a,5sa,8j,3u).
