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.

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

Visitors:
4 people stopped by the site to ask about eagles.

Weather:
The temperature at 0745 was -13C, the high was 6C and it was 2C at 2000. Ground winds were calm to light all day, between SE and SW. Ridge winds were difficult to estimate but seemed to be light from a southerly direction. The day was cloudless with excellent visibility.

Raptor Observations:
The days first Golden Eagles were seen just before 10:00 soaring at Mt.Lorette. Subsequent movement through the rest of the morning until late afternoon was a little slow and sporadic with birds using a variety of different flight paths on both sides of the valley. Flying conditions appeared good and there was quite a lot of high soaring. Numbers increased from late afternoon and these birds were soaring and gliding high above the east ridge before gliding on towards to Mt.Lorette. Almost half (49) the days total number of Golden Eagles were seen between 17:00 and 19:00. A total of 108 birds of 3 species were counted that comprised 2 adult Bald Eagles, 5 Northern Goshawk (2a, 3u), 101 Golden Eagles (84a, 1sa, 16u). Resident Northern Goshawk was seen displaying on several occasions.

Non-raptor Observations:
24 Canada Geese, 14 Snow Geese, 2 Downy Woodpeckers, 2 Hairy Woodpeckers, 3 Canada Jays, 1 Black-billed Magpie, 18 Common Ravens, 5 Black-capped Chickadees, 5 Mountain Chickadees, 12 European Starlings, 2 American Robins, 1 Dark-eyed Junco.

It was a quiet day for visitors. Nearly all the passers-by stopped to chat – a total of 11.

Weather:
Around 2pm we experienced a rather unusual event – a mini tornado. First we heard a rumbling, cracking noise from the other side of the river. Looking in that direction, we expected to see ice crumbling into the river due to melt as it was quite warm. Instead we saw the wind drilling into the ice on the gravel bank, causing pieces of ice to fly up in circles. A few seconds later we were hit by a massive gust of wind that knocked the chairs over – fortunately we were able to grab the scopes before those toppled too. The tornado lasted maybe a minute before the wind dissipated, and it went back to being a mild, sunny day.
The temperature started at -14C, rose to +5C in the late afternoon, and had dropped back to 0C by the time we left. There were no clouds at all, so it was difficult to judge winds. At ground level there was not much wind, other than the twister, until late in the day when there was a continuous strong breeze from the north. The weather station on Centennial Ridge indicated very low winds most of the day, picking up towards the end of the day, with the direction ranging from northwest to northeast.

Raptor Observations:
In spite of the low wind, there was a constant stream of eagles, starting around 1100 and continuing until 1900. The first couple were seen at Mt Lorette, but, until late afternoon, most were seen on the west ridge. Most of these appeared over the left slope of Olympic, rose in thermals, then glided off to the northwest. Around 1700 the movement abruptly switched to the east ridge, with the eagles skimming the top of the ridge and soaring a little to gain enough altitude to make it to Mt Lorette, where they soared again.
The resident Golden Eagle was seen hunting over Hummingbird Plume, and there were two appearances of an adult Northern Goshawk flying low across the meadow. One immature Northern Goshawk was intercepted by a second one that appeared to be chasing it out of the area.
The end tally for migrants was 51 Golden Eagles (49a, 1sa, 1u), one adult Bald Eagle, and one immature Northern Goshawk.

Non-raptor Observations:
The only non-raptor migrants were three European Starlings. Other than a brief squabble between three Hairy Woodpeckers, there was not much going on in the bird world. Other birds were: Common Raven 8, Black-capped Chickadee 4, Boreal Chickadee 1, Pine Siskin 12
