Visitors:
In spite of the snow, about eleven very happy visitors stopped by to find out about the eagles.

Weather:
It snowed almost all day. The temperature started out cold at -8C and stayed almost the same until it the snow thinned out at 16:00, and a bit of sun helped to reach a high of -5C. The ground winds blew between 6-11 Km/h.gusting to 18 Km/h from the North all day, varying between NNW, N, and NNE. It was difficult to see what the ridge winds were doing. When the Eastern ridges were a bit visible, the clouds barely moved but seemed to be pushed from the SE. Later in the day, the clouds on the Western ridges moved from the NNW. At sunset the temperature lowered to -6.5, the winds weakened and the weather vane changed to the South.

Raptor Observations:
Luckily, some Raptors could be located when the snow and clouds cleared periodically in some key locations. All but one were found traveling near Lorette, or on the Fisher range gliding low, flapping, and soaring to maintain height. The final tally was fifteen Golden Eagles (6a, 2sa, 7u), and two Bald Eagles (1a, 1ui). Non-migrating Raptors: A resident Golden displayed repeatedly on the slopes of Old Baldy and a resident adult Goshawk cried out while hunting across the river, giving a beautiful show of strength and artistry.

Non-raptor Observations:
5 American Robins, 7 Ravens (three are always together), 2 Dark-eyed Juncos sp., 1 Black-capped Chickadee, 2 Canada Geese, 5 White-winged Crossbills, and Squirrels. The end of this turbulent day was epic. Everything changed suddenly. Four white-tailed deer moved calmly into the meadow. The winds died down, shifted to the South and a black silhouette of the last Golden Eagle moved west, high into the clouds, ending today’s movie.

About 35 people stopped to chat about the count. Three came during the peak around 4pm and helped spot eagles.

Weather:
The valley sparkled in the morning from a layer of frost over 10cm of fresh powder. From -8 C in the morning, the temperature rose to 0 before falling back down to -1 by sunset. Winds were light at ground level for most of the day, with some gusts over 15km/h in the last hour as snow moved in. Wind direction was variable throughout the day, shifting several times per hour, with wind from the north slightly more than half the time. The clouds were wonderful. Early morning cirrus and altocumulus clouds gave way to constantly morphing cumulus and stratus fractus later in the day, making for favourable locating and identifying conditions (when not subject to backlighting issues).

Raptor Observations:
Both sides of the valley were active, though rarely simultaneously. Migrants slightly favoured the western ridges before noon, then the east ridges until about 4pm when a rush of over 20 Golden Eagles moved from Mt. Kidd to Olympic Summit, soared, and continued north. Unfortunately, by this point in the day these birds were backlit and flying in and out of low clouds, making most of them impossible to age. By 5 pm migration had moved bay to the eastern ridges, where it remained for the rest of the day. Migrants early and late in the day primarily used powered flight; many afternoon migrants made use of thermals above Olympic Summit and Old Baldy. Migration peaked in the 4pm hour with 30 Golden Eagles (and one UE); we observed a total of 66 Golden Eagles (and that one UE) between 3pm and 6pm.
Migrating Raptors: 95 Golden Eagles (52a, 1s, 1 ui, 41u); 6 Bald Eagles (5a, 1j); 4 Unidentified Eagles.
Non-migrating Raptors: 2 adult Golden Eagles, 1 adult Bald Eagle. No sign of the resident Northern Goshawks.

Non-raptor Observations:
The usual trio of chickadee species were sweet on the walk in to the site. Robins, siskins, and juncos provided the day’s soundtrack. Two dippers flew past the site in a highly-charged interaction, the nature of which was not apparent. A lone starling flew through the site late in the day; its plump body and transparent wings seemed out of place against the snow.

24 visitors stopped to talk, none came to watch raptors

Weather:
At the beginning of the day it was -2C with light wind, the mountain ridges were mostly obscured and light snow was falling. Throughout the morning the snow slowed and the sky partially cleared. The afternoon was one of of contrasting weather as snowstorms moved through occasionally, but otherwise it was sunny and warm. The high was 3C. Ground wind direction varied from SW through NW to NE, speed was usually up to 10km/h but some gusts over 20 accompanied snowstorms. Ridge wind was from the NW, light to moderate in the morning and moderate to strong in the afternoon. The ridges were partially obscured almost all day. Around 6 PM a larger snowstorm moved in from the north bringing heavy snow and fully obscuring all ridges. The weather radar didn’t show any sign of it clearing so the count was concluded at 6:30 PM

Raptor Observations:
Migrants primarily used the western ridges, especially during peak hours, but some were popping up on the eastern ridges as well. The most common route for Golden Eagles was to fly out from between Mts. Bogart and Kidd to the south flank of Olympic Summit, then soar to gain height before continuing along the Kananaskis Range. For the first few hours of migration eagles were low and primarily flapping. In the afternoon the wind picked up and some thermals developed so birds tended to be higher, mostly soaring but a few found strong enough updrafts to kite. Despite the poor forecast a strong movement of eagles braved the weather, most of them concentrated in 2 hours in the afternoon. The peak was between 2 and 3 pm, with no less than 139 Golden Eagles (76ad, 3sa, 60u) and 1 adult Bald Eagle counted. The highlight of the day was just before 3 PM when 39 Golden Eagles were visible in the sky at once, with about 30 in a kettle over Olympic Summit and the remainder coming and going from it. The full count for the day was 205 Golden Eagles (120a, 6sa, 1j, 78u) and 5 Bald Eagles (3a, 2sa). Conditions for ageing were usually good but time was a limiting factor. Local raptors included the Golden Eagle pair displaying south of Olympic Summit, two immature Bald Eagles harassing each other north of the site, and at least one adult Northern Goshawk seen several times.

Non-raptor Observations:
Canada Goose 2 Hairy Woodpecker 1 Northern Flicker 1 Canada Jay 1 Common Raven 8 Black-capped Chickadee 4 Mountain Chickadee 1 Boreal Chickadee 1 European Starling 100 Varied Thrush 1 Bohemian Waxwing 120 Pine Grosbeak 1 Pine Siskin 5 Dark-eyed Junco (unknown ssp.) 2 Dark-eyed Junco (Oregon) 1
Red Squirrel 2 Mink 2 (one chasing another early in the day, one alone later)

Visitors:
8 people stopped by to ask what we were doing.

Weather:
The temperature rose to 1C from a low of -5C. Ground winds were light E or calm, while ridge winds were mainly light to moderate W becoming light NE in the afternoon. Cloud cover was 70-100% cumulus with stratocumulus gradually thickening and lowering through the day. Some light snow flurries from late morning. We moved the watch site to Wasootch Creek at 15:00 but conditions continued to deteriorate so the count was ended at 16:00.

Raptor Observations:
A total of 29 migrants were seen between 10:20 and 14:00. The first Golden Eagles were seen circling over the summit of Mt. Kidd, all further birds were seen on the eastern side, usually gliding near ridge level with some soaring. One Golden Eagle gave us a rare close sighting as it came gliding down river passing c.50m above us. The only other species seen was a young Northern Goshawk. Total 28 Golden Eagles (19a, 9u).

Non-raptor Observations:
3 American Robins were singing near the meadow at dawn. Canada Goose 3, Canada Jay 2, Northern Flicker 2, Downy Woodpecker 3, Common Raven 12, Black-capped Chickadee 2, Red Crossbill 1, Pine Siskin 3.

Not many people came by today. Of those, seven stopped to talk.

Weather:
The seemingly endless blue skies finally gave way today to layers of cumulus and cirrus clouds, but not until the last couple of hours of observation. For most of the day it was a challenge to find migrants in the blue, especially as there was a bit of haze as well. Ground winds were light in the morning, increased a bit during the day and tapered off in the evening. The temperature started at -9C, reached a high of +5C, and dropped to 0C at the end of the day. It was difficult to determine ridge winds, but they appeared to be light, from the west, for most of the day as there was much soaring needed for the migrants to make any progress. The ridge winds appeared to increase as the day went by.

Raptor Observations:
Not many migrants were spotted in the morning, and in the afternoon the numbers gradually increased as the wind became more favourable for migration. The highest hourly number, 35, occurred between 17:00 and 18:00. In the morning the migrants were mostly on the west ridge. It was difficult to spot any on the east ridge initially, but quite a few were picked up over Mt Lorette, some appearing to have come from Patrick, and some appearing to have gone over our heads. Late in the day most migrants were flying high over the east ridge, but there were still a few appearing on the west ridge too. Overall it was quite challenging with birds on both sides of the valley and overhead, with no consistent path until the last hour or so.
The final tally of migrants was 104 Golden Eagles (89a, 15u), one Northern Goshawk, five Bald Eagles (4a, 1sa), and one small accipiter. It is interesting to note that more than 1/3 of the Golden Eagles that have been seen so far this season were seen in the last two days.
There were three non-migrant raptors: one Golden Eagle, one Northern Goshawk, and one Bald Eagle.

Non-raptor Observations:
Other birds were: Canada Goose 3, Hairy Woodpecker 1, Northern Flicker 1, Black-billed Magpie 1, Common Raven 7, Black-capped Chickadee 2, Boreal Chickadee 2, European Starling 1, American Robin 1, Pine Grosbeak 1, White-winged Crossbill 5, Pine Siskin 6, Red-winged Blackbird 1
