The Golden Eagle Migration Count

migration-sites-ab_(1)

Every fall Golden Eagles migrate from their breeding grounds north of us to wintering grounds to the south. In the spring they fly back to their breeding grounds. One of the main routes for this migration is along the front ranges of the Canadian Rockies. At our watch site on the banks of the Kananaskis River near Mount Lorette, we count the passing eagles, and other raptors, for nearly eight weeks each spring and fall.

The Spring 2026 Migration Count runs from March 1 to April 22 with observers at the Mount Lorette site daily. We welcome visitors, and suggest that if you are interested in visiting the site then come in the mid-afternoon, which is when we typically see the highest number of eagles.

You can follow along with the count by reading the daily blog below, and you can learn more about Golden Eagles and the count by browsing the pages on this website. Got questions? We’ve got answers!

Visitors:
17 visitors came by but only one couple stopped to visit.

Weather:
Temperature this morning was minus 9 Celsius and rose to minus 4. Cloud covered most of the sky for the day with some blue areas in the east. Cumulus and Stratus clouds filled the western ridges and spilled heavily into the south. There were scattered snow flurries during the morning and by 2 pm the whole sky was covered and it began to snow in earnest. The wind was light from the north, northeast. Ridge winds were moderate ,spinning columns of snow off the ridge tops and when visible the high clouds were moving quickly to the east. Once the heavier clouds socked in, there was no obvious movement.

Raptor Observations:
The first eagle was seen high over the eastern ridges sailing very fast. There was no time to identify it as more than an eagle. The only other eagle was seen flying low in front of Patrick and over to Lorette. As it dipped over the ridge, the base of it s tail showed white, indicating undifferentiated subadult.

Non-raptor Observations:
Other birds seen or heard were 4 Dark-eyed Juncos, 2 Varied Thrushes, 12 American Robins, 6 European Starlings, 4 Common Ravens, 4 Mountain chickadees, 2 Northern Flickers, 1 Golden-crowned Kinglet, 1 American Dipper 1 Belted Kingfisher and three flocks of silent, little brown birds 30-40 in each group.

Visitors:
31 People stopped to talk. 4 came with binoculars to watch for eagles.

Weather:
The temperate was -3 C at the start of observation, it rose to a high of 2, then fell to 0 as we were leaving. Ground wind was from the N-NW, 5-10 km/h in the morning and gusting up to 20 in the afternoon. Ridge wind was light from the NE, up to 13. High wind was moderate to strong from the SW. The collision of weather systems created a haze that made identification of distant raptors very difficult, and ageing impossible in most cases. Cloud cover was 20-30% cumulus and cirrus in the morning, but increased in the afternoon as the storm approached. Around 4 PM low cloud and snow began to envelop the west ridges, then started creeping into the valley to the north and south of the site. The count was concluded at 4:45 PM as snow reached the meadow and the east ridges began to disappear.

Raptor Observations:
Migration was slowish and somewhat sporadic between 12:45 and 4 PM. The count for the day was 27 raptors including 21 Golden Eagles (2 adults, 1 subadult, 18 u), 2 Bald Eagles (1 adult, 1 subadult), 1 Red-tailed Hawk, and 3 unidentified eagles. Movement was split between east and west ridges, and migrants were relatively low (often passing behind or in front of the mountains) given the poor flying conditions. Resident raptors included the Golden Eagle pair, one of which was displaying over Olympic Summit, an adult Goshawk that flew over the meadow carrying unidentified prey, and a Red-tailed Hawk that was displaying and harassing the migrating Red-tail.

Non-raptor Observations:
The most unusual bird of the day was a Spotted Towhee foraging with a group of Juncos. Other birds were 2 Canada Geese, 1 Common Merganser, 1 Belted Kingfisher, 1 American Three-toed Woodpecker, 1 Hairy Woodpecker, 1 Northern Flicker, 8 Common Ravens, 1 Black-capped, 1 Mountain, and 2 Boreal Chickadees, 2 Golden Crowned Kinglets, 3 Red-breasted Nuthatches, 4 European Starlings, 2 Varied Thrushes, 6 American Robins, 15 Bohemain Waxwings, 3 Pine Siskins, and 7 Dark-eyed Juncos (3 Oregon, 4 u). 3 White-tailed Deer were also seen.

Visitors:
About 28 people came by, and 14 stopped to chat and help look.

Weather:
Temperatures rose quickly from -8�C to 2�C, but sharp winds kept it brisk! For much of the days the ground winds blew around 15km/h, with gusts of up to 43km/h. Pressure dropped by a couple points throughout the day, and clouds cover varied from cirrus to cumulus to even a bit of lenticular, but rarely enough to fully cover the sky. Ridge winds looked strong from the SW based on the plumes of snow blowing off the peaks, but the Nakiska Ridgetop weather station was down so no exact numbers were obtained.

Raptor Observations:
Golden Eagles came slow and steady for most of the day after 11:00, apart from one burst between 12:30 and 1:00. This led to our highest hour, with 10 Goldens and 12 raptors in total. The final count was 31 Golden Eagles (18 adult, 11 unknown, and 2 subadults).
2 Bald Eagles (1a, 1s) and 4 Red-tailed Hawks also passed over. The Hawks were a fun mix, with three dark morphs – two ‘calurus’ and one Harlan’s – and one pale bird of the ‘abietacola’ subspecies.
Also entertaining was the resident Golden Eagle pair. The male performed an extended aerial display at various point across the Eastern slope, while the female feigned disinterest. The resident Goshawk, and an adult Bald Eagle made appearances.

Non-raptor Observations:
Perhaps because of the wind, it felt quiet today, but when there were birds it was a good variety. A male Red-winged Blackbird sang from several treetops, which were later occupied by the Northern Shrike. A Northern Flicker and a Hairy Woodpecker made absolutely sure they were heard by all around, and the first American Tree Sparrow of the year showed up at long last.

Observers: Guy Kerr

Visitors:
6 people stopped to chat, including a couple with binoculars who stayed for a while to help.

Weather:
The start of the count was delayed until 0900 due to poor visibility. The temperature at 0900 was -14C, the high at 1700 was -4C. It was initially calm at ground level then light variable for the rest of the day. Ridge winds were initially highly variable with different ridges having snow plumes blowing in opposite directions to the ones on the other side of the valley, but they became moderate to strong SW by late morning. Cloud cover was also mixed but generally the east ridges and overhead were clear with some cumulus. Much thicker stratocumulus and stratus clouds persisted to the south and west for most of the day. 100% stratus from 1445 to 1615 brought periods of light snow before gradually clearing again. No Golden Eagles were seen after 1630 so the count was ended a little early at 1920.

Raptor Observations:
The mixed conditions produced a disappointing count of 28 migrants that comprised 4 Bald Eagles (3a, 1sa), 2 adult light morph calurus Red-tailed Hawks, 2 Rough-legged Hawks and 20 Golden Eagles (15a, 5u). All Golden Eagles were seen over the eastern ridges. Before the mid-afternoon snowfall, the eagles were flapping and gliding just above ridge level before crossing the river valley, in quite a steep glide, taking them well to the east of Mt Lorette and quickly disappearing out of sight. When the snow cleared at 1615, 3 Golden Eagles appeared over Mt McDougall gliding north at a higher altitude, indicating that flying conditions had become more favourable. We hoped that we would have a busy evening but sadly we saw our last Golden Eagle of the day at 1630.

Non-raptor Observations:
The Northern Pygmy Owl was calling for much of the day but remained stubbornly out of sight. Other birds were: 15 Canada Geese, 6 Mallards, 1 Hairy Woodpecker, 1 Northern Flicker, 7 Common Ravens, 3 Black-capped Chickadees, 1 lone European Starling that hung around for much of the day, 16 American Robins, 2 Pine Siskins, 1 Dark-eyed Junco.

Observers: Peter Lloyd

Visitors:
The thick snow is likely at fault for our complete lack of visitors today. Coincidentally, the sk-hill was very busy!

Weather:
The day started out with a heavy snowstorm, which blanketed the valley in low clouds and dumped around 20-25cm over the course of a few hours. By noon it showed some signs of lifting, and by 1:00pm, ridgelines began to become visible. A pleasant calm settled, with very low winds, some sun, and a strong scattering of cumulus clouds up above. This lasted until around 6:30pm, when a sudden north wind swept into the clearing gusting up to 35km/h. The wind brought with it an increase in clouds and a decrease in temperature, and lasted until we lost the ridgelines again at 7:45pm. The temperature was -1ºC at 1:00, and held at zero until it dropped to -6ºC by 7:00.

Raptor Observations:
Within a few minutes of the ridgelines clearing, the first eagles of the day were spotted gliding over the Eastern ridgeline. Goldens continued in trickles until the final two hours of the day, when 11 Eagles in 15 minutes contributed to our busiest hour (17 between 6:00 and 7:00). In total, 53 Golden Eagles were counted, almost all along the Eastern side. One unidentified Eagle dipped behind Mt. Patrick and was never picked up again.
We did see a resident sub-adult Bald Eagle, which cruised southwards along the powerline.

Non-raptor Observations:
Upon arriving, a European Starling was unceremoniously evicted from the kiosk, where it had been taking shelter from the storm. This same Starling hung around and was seen over a dozen times during the afternoon. Also seen were a pair of Hooded Mergansers, which flew low overhead late in the day, as well as a smattering of Robins, Juncos, and Redpolls. Two male Mountain Bluebirds paused briefly in the meadow.

Visitors:
I would have been very surprised had there been any visitors so early in the morning on such a windy, snowy, cold day. There were none.

Weather:
Spring weather. There was some hope that just maybe the snow would hold off a little bit this morning and there would be a continuation of yesterday’s flight, but it was not to be. Although the sky was overcast, the ridges were clear on arrival at sunrise, but first the west ridge dissolved into the mist, and then clouds draped over the east ridge, bringing light snow that was forecast to worsen and continue for the rest of the day, so the count was abandoned after less than an hour. Ground winds were in the range 20-30kph from the northeast – migrant eagles are rarely seen when the wind is from that direction. For that brief time the temperature was -5C.

Raptor Observations:
In spite of the conditions, one unaged Golden Eagle was seen flying briefly above the east ridge.

Non-raptor Observations:
Other birds around were a small flock of starlings, some Canada Geese, a small flock of crows heading north, and a couple of Varied Thrushes.

Predictions:
Tomorrow is looking better than today, but some flurries may get in the way of the migration. The next big days could be Friday and Saturday this week.

Observers: Glenn Webber

Visitors:
About 25 visitors came to the site, and a few helped with binoculars. A combined group of students from multiple schools stopped by for an educational visit about the eagles.

Weather:
The temperature at the start of the count was -6ºC, rising to 6ºC and falling to 4 at the day’s end. The sky was totally covered with low-lying cloud, and none of the ridges were visible until around 10:00. Wind came from the north until 12:30, when it changed to W and SW for the remainder of the day. It blew at 1-2 Beaufort in the morning and 3-4 in the afternoon with some very intense gusts. One unexpected gust at 16:25 nearly carried us into the river! The weather station at the Nakiska Ridgetop is still not working, but the snow plumes on the ridges indicated very strong westerly wind at that level. Cloud coverage averaged about 40% and included cumulus, stratocumulus, and by the end of the day was mainly cirrostratus.

Raptor Observations:
All but a handful of birds used the east ridges. At first, we located the majority of the birds at Mount Lorette. But as the day progressed, we discovered their flight path extremely high above the North Fisher range. Near the end of the day, they flew straight over Lorette without stopping to fly across the escarpment and onto McGillivray, as did most of the birds today. Aging was exceedingly difficult due to atmospheric humidity, distance of flight, backlight conditions, and flight style. Also, because of the high winds, many of the eagles glided with wings tucked in. The total number of raptors was: 187 golden Eagles (76 a, 2 sa, 1 j, 7 ui, 101 u), 12 Bald Eagles ( 7a, 4 sa, 1j), 1 American Goshawk. A resident Golden Eagle, American Goshawk and Bald Eagles were seen.

Non-raptor Observations:
The Northern Pygmy-owl sounded throughout the day, and the male Mountain Bluebird made an appearance before the Northern Shrike appeared. Other birds included 40 European Starlings, 3 American Robins, 3 Varied Thrush, 1 Northern Flicker, Pine Siskins, 1 Mountain Chickadee, Dark-eyed Juncos, Hairy Woodpecker, 1 Bohemian Waxwing, 12 Canada Geese, Ravens.
