Friday, March 29 Mount Lorette [Day 27] 0715-2005 (Caroline Lambert, assisted by Patrick Farley, Patricia Farley and Doug Pederson). The temperature at 0715 was -1C, the high was 8C at 1700 and 1800 and it was 1C at 2000. Ground winds were light and variable all day with the exception of around 1500 when they gusted to 15 km/h from the S, while ridge winds were also mainly light and variable all day. Cloud cover was initially 90% cumulus, altocumulus and altostratus that gradually dwindled to 10% cirrus at 1800 before increasing to 50% cirrus and expanded contrails late in the day. Both ridge systems were initially obscured with the east clearing after 0900 and the west clear after 1100. There was a moderate raptor movement that involved only eagles between 1040 and 1940 comprising 2 adult Bald Eagles, 55 Golden Eagles (45a, 4sa, 1j, 5u) and 1 unidentified eagle. With the exception of one bird all movement was on the western route until 1720 where birds mainly soared high over Olympic Summit before gliding high to the NW behind the summit of Mount Allan, but after 1720 soaring birds were located on the eastern route over the Fisher Range or Mount Lorette. Movement was steady throughout the day but significantly increased after 1800 with 14 and 10 Golden Eagles seen between 1800 and 1900, and 1900 to 1940 respectively. A resident adult Northern Goshawk were heard calling east of the river early in the morning and 1 later hunted over the west valley, and a juvenile hunted above Hummingbird Plume Hill in the mid-afternoon; and the Golden Eagle pair was seen once, hunting against the face of Mount Bogart. Other birds in the area were 6 Canada Geese, 1 drumming Ruffed Grouse, 1  Pileated Woodpecker, 1 Northern Shrike, 1 Canada Jay, 1 Black-billed Magpie, 16 Common Ravens, 3 Black-capped Chickadees, 6 Mountain Chickadees, 3 Boreal Chickadees, 2 Red-breasted Nuthatches,  2 male Mountain Bluebirds that riskily shared the meadow with the shrike around 1500, 5 singing Varied Thrushes, 3 American Robins, 20 European Starlings, a flock of 20 Bohemian Waxwings that flew north and 7 singing Dark-eyed Juncos. Four Bighorn Sheep were on Olympic Summit and an American Mink was seen on the river bank at the site and entertained several of today’s 20 visitors.

Friday, March 29 Beaver Mines [Day 27] 0730-2000 (Peter Sherrington, assisted by Gord Petersen and Hilary Atkinson). The starting temperature at 0730 was -1C, the high was 6.5C at 1800 and it was 2C at 2000. Winds were mainly NE 5-15 km/h in the morning that became light to 1600, after which they were light SW-SSW for the rest of the day. Cloud cover was 100-70% mainly stratocumulus and cumulus to 1730, with the exception of 1000 and 1100 when it was 30-40% cumulus and cirrus, but after 1730 the sky cleared to 40-20% cumulus, cirrostratus and expanded contrails which gave sunny conditions at the end of the day. The day started promisingly with a Sharp-shinned Hawk flying north at 0929 and 2 Golden Eagles gliding high to the north at 1048 and 1055, but a third Golden Eagle was not seen until 1510 and the only sustained movement was when 20 Golden Eagles soared high above the SW flank of the ridge between 1641 and 1742 including 8 that soared together at 1655. The last bird of the day was an adult Bald Eagle at 1841. The final count of 29 birds was 2 Bald Eagles (1a, 1j), 1a Sharp-shinned Hawk, 2a Northern Goshawks and 24 Golden Eagles (22a, 2sa). The resident pair of Golden Eagles soared above the ridge together between 1141 and 1155, and the resident juvenile perched at the top of the hill at 1545. Other birds seen were 4 Canada Geese, 2 Mallards, a flock of 60 Northern Pintails that flew high to the north at 1054, 53 Wild Turkeys, 16 Rock Pigeons, 4 Downy Woodpeckers, 1 Northern Flicker, 5 Blue Jays, 2 Black-billed Magpies, 10 American Crows, 19 Common Ravens, 2 Black-capped Chickadees, 2 Mountain Chickadees, 4 American Robins, 36 European Starlings, 21 Evening Grosbeaks, 55 Grey-crowned Rosy-Finches that flew high to the north in 2 flocks at 1825 and 1845, 2 female Cassin’s Finches, 8 Pine Siskins and 8 Dark-eyed Juncos (1 hyemalis, 2 cismontanus and 5 montanus).

Friday, March 29 Steeples [Day 24] 1200-1830 (Vance Mattson). The temperature reached 13C from a starting low of 7C, conditions were initially calm with light E winds developing later and 80% cumulus cloud cover at the start reduced to 20% at the end of the day. Only 3 migrants were seen between 1418 and 1757: 1 adult Bald Eagle and 2 Golden Eagles (1a, 1j). Non-migrant activity was somewhat more eventful with a resident Golden Eagle soaring high above the site from 1630 to 1641, 7 Bald Eagles (5a, 2j) that included a pair-flight and extended dueling of the juvenile birds in which an adult briefly joined in, and the first sightings of the resident pair of Northern Goshawks that chased and dived at each other at 1659. The ice was fully melted on Wasa Lake and 7 Bald Eagles (3a, 1sa and 2j) fished the lagoon and a spirited territorial battle between 2 adults was seen after which to two combatants parted the scene in opposite directions.

Thursday, March 28 Mount Lorette [Day 26] 0715-2005 (Blake Weis, assisted by Rick Robb). The starting temperature was -2C, the high at 1600 and 1700 was 5C and it was 4C at the end of observation. Ground winds were N-NE 0-5 km/h to 1100, S-SW 0-5 gusting 10 km/h to 1700 and then N-NE 0-5 km/h again for the rest of the day, while ridge winds were light NW to 1100 and then W-NW light to moderate. Cloud cover was 100-90% cumulus, altocumulus and stratocumulus to 1000, variable 60-90% altostratus, altocumulus and cumulus to 1700 and then 60% altocumulus to the end. All ridges were initially obscured but gradually cleared throughout the morning and all were completely clear by 1300. Light snow fell to 1000. There was  fairly strong raptor movement of 144 birds of 4 species between 1018 and 1915 that comprised a season-high 36 Bald Eagles (26a, 3sa, 1j, 3 undifferentiated immature birds and 3u), 102 Golden Eagles (79a, 1sa, 1j, 21u), 4 unidentified eagles, the season’s first Gyrfalcon, a grey morph and 1 Prairie Falcon. With a couple of exceptions movement was exclusively on the western route from Mount Kidd to Olympic Summit and thence to the NW over Skogan Pass to 1300, after which movement was equally divided between the western and eastern routes (Fisher Range to Mount Lorette). The light winds produced much soaring flight with a maximum kettle of 7 Golden Eagles over Olympic Summit. Movement was persistent and steady to 1800 with a high hourly count of 26 (2 Bald Eagles, 22 Golden Eagles and 2 unidentified eagles) between 1500 and 1600, but 1800-1900 produced just 1 Golden Eagle and 1900-2000 just 1 Bald Eagle. A resident Northern Goshawk called early in the morning near the parking area, and later 2 probable adult males flew above the western valley with one bird performing a display flight before harassing the second bird, and the resident Golden Eagle pair were seen several times displaying and perching together in the vicinity of Olympic Summit. Other birds seen in the area were a flock of 25 Snow Geese that flew north above the Fisher Range at 1415, 6 Canada Geese, 1 drumming Ruffed Grouse, 1 Hairy Woodpecker1 Northern Flicker, 2 Pileated Woodpeckers, 2 Canada Jays, 1 American Crow, 16 Common Ravens, 4 Black-capped Chickadees, 4 Mountain Chickadees, 2 Boreal Chickadees, 1 Red-breasted Nuthatch,  4 singing Varied Thrushes, 4 American Robins, 55 Bohemian Waxwings in 3 flocks all of which flew south, 1 Common Redpoll, 4 White-winged Crossbills, the first American Tree Sparrow of the season and 7 Dark-eyed Juncos. Ten visitors were at the site today.

Thursday, March 28 Beaver Mines [Day 26] 0900-2000 (Peter Sherrington, assisted by Hilary Atkinson). The temperature at 0900 was -3C, the high at 1600 was 3C and it was 0C at 2000. Winds were light (<10 km/h) and variable to 1800 when they became light SW-W. Cloud cover was 100% stratus 1745 when it began to quickly break and by 1800 it was 30% cumulus and at 1900 it was cloudless, after which altostratus developed that reached 80% at 2000. The ridge cleared at 0900 that allowed observation to start, but snow persisted to 1150 that left 8 cm of fresh snow on the ground. There was again a disappointing and very sporadic raptor movement involving 28 birds of 3 species that moved to the north between 1304 and 1653 comprising 3 Bald Eagles (2a. 1sa), 1 adult light morph calurus Red-tailed Hawk and 24 Golden Eagles (21a, 1sa, 2j). With the exception of a juvenile Golden Eagle at 1419 all birds moved in two waves, the first of 9 birds between 1304 and 1352 and the second involving 18 birds between 1522 and 1653 that included the highest hourly count of 13 (all Golden Eagles) between 1600 and 1700. All birds soared high above the ridge before gliding to the north, with some birds disappearing into the base of the stratus cloud. Other birds seen were 33 Canada Geese, 16 Rock Pigeons, 4 Downy Woodpeckers, 2 Hairy Woodpeckers, 1 Northern Flicker, 6 Blue Jays, 1 Black-billed Magpie, 60 Common Ravens, 5 Black-capped Chickadees, 1 Mountain Chickadee, 1 Townsend’s Solitaire, 9 American Robins, 111 European Starlings, 30 Evening Grosbeaks, 1 singing Cassin’s Finch, 50 Pine Siskins and 9 Dark-eyed Juncos (1 hyemalis, 3 cismontanus and 5 montanus).

Thursday, March 28 Steeples [Day 23] 1400-1830 (Vance Mattson). The temperature was 9C to 10C, conditions were calm and cloud cover was 80-100% altostratus and dark cumulus. A total of 7 eagles that comprised 2 Bald Eagles (1a, 1sa), 4 Golden Eagles (3a, 1u) and 1 unidentified eagle. With the exception of the subadult Bald Eagle at 1734, all birds migrated between 1416 and 1535. Non-migrant birds were 6 Bald Eagles (3a, 1sa, 2j) that included a pair that flew west together into the valley, and three sightings of adult Golden Eagles including one that made a brief display flight.

Wednesday, March 27 Mount Lorette [Day 25] 1430-1945 (Caroline Lambert). Snow, sometimes heavy, fell all day and the mountains were obscured, but Caroline arrived in the area at 1945 when it appeared that the snow was easing. She spent a couple of hours unsuccessfully searching for a clear ridge between Kananaskis Village and Lusk Creek before finally arriving at the Hay Meadow site. The temperature was 0C at 1430, reached a high of 2C at 1600 and was again 0C at 1945. Ground winds were NE-NW 0-5 gusting 10 km/h and ridge winds were also probably light. Cloud cover was 100% stratocumulus that briefly cleared to 80%, the east ridges were 100% obscured to 1800 but cleared to 80% late in the afternoon and the west was 100% obscured all day. Snow continued to fall throughout. The only migrant raptor was an unidentified eagle that glided to the north from Mount Old Baldy along the Fisher Range at 1611; an adult bird that soared low on the southern flank of Mount Allan and flew to the north was considered to be one of the resident pair. Other birds seen were 1 Black-billed Magpie, 1 Common Raven, 2 Black-capped Chickadees and 2 Mountain Chickadees and, not surprisingly, there were no visitors today.

Wednesday, March 27 Beaver Mines [Day 25] 0730-1915 (Peter Sherrington, assisted by Hilary Atkinson). The temperature at 0730 was -3C, the high at 1400 was 4C and it was 0C at 1915 when heavy snow ended observation. Winds were light (5 km/h) and variable to 1330 after which they were NE-ENE 5-10 gusting up to 18 km/h. Cloud cover was 100% low stratus all morning that obscured the ridge to 1015 and produced light freezing rain to 0830. The afternoon saw 100% stratocumulus cloud except between 1630 and 1715 when it reduced to 60-80% and allowed brief sunny breaks. At 1830 thick dark stratocumulus moved from the north bringing snow that persisted to the end of observation. Despite the generally unfavourable conditions there was a slow but persistent raptor movement of 20 birds of 6 species between 1052 and 1850 that comprised 2 Bald Eagles (1a, and 1 undifferentiated immature bird that was just discernible in the snow at 1850), 2 female Northern Harriers (1a, 1j), 1 adult Sharp-shinned Hawk, 2 light morph Rough-legged Hawks the second of which moved just ahead of the advancing snow storm at 1834, 12 adult Golden Eagles 11 of which were seen between 1506 and 1705, and 1 juvenile female Prairie Falcon that flew north at 1052. Other birds seen were 49 Canada Geese, a flock of 10 Trumpeter Swans that flew high to the north at 1338, 2 Mallards, 20 Rock Pigeons, 4 Downy Woodpeckers, 2 Northern Flickers, 14 Blue Jays, 2 Black-billed Magpies, 16 American Crows, 18 Common Ravens, 4 Black-capped Chickadees, 4 Mountain Chickadees, 1 Red-breasted Nuthatch, 3 American Robins, 121 European Starlings, 20 Evening Grosbeaks and 14 Pine Siskins. Yesterday (March 26) Cornell VanRyk reported the area’s first Ferruginous Hawk this year, an adult light morph bird, at his home on the lower Castle River 10 km ENE of Beaver Mines.

Wednesday, March 27 Steeples [Day 22] 1645-1830 (Vance Mattson). A Wednesday teaching commitment again prevented Vance from arriving at the site before 1645 where the temperature was 11C, conditions were calm and cloud cover was 40-80% cumulus and altostratus. No migrants were seen, but a resident and juvenile Golden Eagle were present with the juvenile soaring low near the site, and a subadult Bald Eagle was soaring when Vance arrived, but glided to the south.

Tuesday, March 26 Mount Lorette [Day 24] 0735-1950 (Blake Weis, assisted by Katherine Peterson). The temperature at the start was -2C, the high was 7C at 1300 and it was 0C at the end of observation. Ground winds were S-SW all day, 0-3 km/h to 1000 then 0-5 gusting 20 km/h to 1800 after which they were 0-5 gusting 10 km/h for the rest of the day, while ridge winds were moderate SW all day. Cloud cover to 1200 was 90-30% altocumulus, altostratus, cumulus and cirrus, but by 1300 it was 100% stratocumulus that brought snow flurries. The eastern ridges were clear to 1100 but by 1500 were 100% obscured, while the west was 10% obscured to 1000, 70-80% obscured to 1400 and by 1500 it was also 100% obscured. At 1535 the observers decided to relocate to the Lusk Creek site where the ridges were clear and cloud cover was 50-70% altostratus, altocumulus and cumulus. The first 6 Golden Eagles were seen from the Hay Meadow at 0918 and a total of 112 migrants, 1 Bald Eagle, 1 Northern Goshawk and 110 Golden Eagles were seen before the move to Lusk Creek with high hourly counts of 37 Golden Eagles between 0900 and 1000, and 25 Golden Eagles between 1100 and 1200. Lusk Creek produced a further 108 migrants up to 1930 comprising 102 Golden Eagles, 5 unidentified eagles and 1 small unidentified raptor, with the 3 hours after 1600 producing 27, 25 and 38 migrants respectively. The final combined count was a season-high 220 birds that comprised 1 adult Bald Eagle, 1u Northern Goshawk, a season-high 212 Golden Eagles (53a, 1sa, 158u), 5 unidentified eagles and 1 small unidentified raptor. At Hay meadow all birds initially moved high from the Fisher Range to Mount Lorette but moved at lower elevations as the weather deteriorated. The cloud conditions produced mainly silhouetted views of the migrants that resulted in the high number of unaged Golden Eagles. Resident birds seen at Hay Meadow were 1 subadult Bald Eagle, 1 adult Northern Goshawk and 1 adult Golden Eagle, while at Lusk Creek 1u Northern Goshawk and 1 adult Golden Eagle that moved to the south were considered to be non-migrants. Other birds seen at Hay Meadow were 1 Canada Goose on the river, 1 Hairy Woodpecker, 2 Canada Jays, 16 Common Ravens, 1 Black-capped Chickadee, 1 Mountain Chickadee, 1 Boreal Chickadee, 1 American Dipper, 4 singing Varied Thrushes, 5 American Robins, 4 European Starlings, 6 White-winged Crossbills, 1 Pine Siskin and 5 Dark-eyed Juncos. Only 2 visitors came to the Hay Meadow site today. Additional bird species seen at Lusk Creek were 1 Northern Pygmy-Owl that was chased away by 4 White-winged Crossbills, 2 Red-breasted Nuthatches, 1 Brown Creeper and a flock of 100 Bohemian Waxwings.

Tuesday, March 26 Beaver Mines [Day 24] 0730-2000 (Peter Sherrington, assisted by Hilary Atkinson). The temperature at 0730 was 4C, the high was 9.5C at 1500 and it was 3C at 2000. Winds were strong WSW all day 40-50 gusting to 70 km/h, and cloud cover was mainly 40% altostratus, cumulus and cirrostratus that gave excellent observing conditions, except at 1300 and 1400 when 90% cumulus and altostratus gave occasional rain and sleet showers, and after 1900 when it was essentially cloudless. The conditions produced a moderate raptor migration of 56 birds, with a season-high 10 species moving between 0805 and 1913. The count was 6 Bald Eagles (5a, 1sa), 1u Sharp-shinned Hawk (the first of the season), 3a Northern Goshawks, a season-high 3 adult calurus Red-tailed Hawks (2 light, 1 dark), a season-high 3 Rough-legged Hawks (2 light, 1 dark), a disappointing 35 Golden Eagles (33a, 1sa, 1j), the first 2 columbarius Merlins of the season (1a female, 1u), 1 female grey morph Gyrfalcon, the first Peregrine Falcon of the season, an adult male and 1 Prairie Falcon. The first Peregrine Falcon also occurred on this date last year. Movement was again sporadic with high hourly counts of only 10 birds between 1100 and 1200, and again between 1400 and 1500. Other birds seen were 2 Canada Geese, 18 Rock Pigeons, 1 Downy Woodpecker, 1 Hairy Woodpecker, 8 Blue Jays, 3 American Crows, 32 Common Ravens, 1 Black-capped Chickadee, 4 American Robins, 98 European Starlings, 37 Evening Grosbeaks and 5 Pine Siskins.

Tuesday, March 26 Steeples [Day 21] 1400-1900 (Vance Mattson). Initially the temperature was 9C, winds were strong S and cloud cover was 50-80% cumulus and altostratus. The ridges were obscured from 1600 to 1650 after which cloud reduced to 30% cumulus and winds became moderate S. A total of 7 Golden Eagles (4a, 1sa, 1j, 1u) migrated between 1501 and 1814 with 3 moving between 1501 and 1533 and 4 between 1756 and 1814. One non-migrant adult Bald Eagle was also seen.

Monday, March 25 Mount Lorette [Day 23] 0715-2015 (George Halmazna, assisted by Dan and Cindy Parliament). The temperature reached 10C at 1600 and 1700 from a morning low of -2C and was 3C at 2015. Ground winds were NW-W 0-2 km/h to 1100 after which they were SW for the rest of the day, mainly 5-10 km/h but 8-15 km/h between 1400 and 1700 and again 0-2 km/h after 1700, while ridge winds were SW light to moderate. Cloud cover was 100% altostratus with minor cumulus to 1000 that diminished to 30% cumulus at 1400 and 90% thin cirrostratus formed for the last 2 hours of observation. Location of high-flying birds in the blue sky was often challenging where cloud was absent and during the last 2 hours birds could only be aged when they flew against the face of Mount Lorette. The day produced a season-high count of 217 migrant raptors between 1101 and 1942 that comprised 6 Bald Eagles (5a, 1j), 1 adult Northern Goshawk and a season-high 210 Golden Eagles (202a, 1sa, 5j, 2u). All birds moved high or very high on the eastern route above the Fisher Range ridge to Mount Lorette where a few birds soared. Migration was strong and steady throughout the migration period and peaked between 1800 and 1900 when 65 Golden Eagles were seen. Resident birds were 3 adult Bald Eagles, a pair and a single bird, and 1 adult Golden Eagle that flew south from Hummingbird Plume Hill to Olympic Summit at 1242. Other birds seen in the area were 2 Snow Geese that flew from the Fisher Range to Mount Lorette at 1658, 2 Canada Geese, 25 adult white-headed gulls of unknown species that flew high to the north, 1 Northern Flicker, 1 Pileated Woodpecker, 2 Canada Jays, 19 Common Ravens, 1 Black-capped Chickadee, 2 Mountain Chickadees, 3 Red-breasted Nuthatches, 2 Varied Thrushes, 3 American Robins, 1 American Dipper, 1 Lapland Longspur and 4 “Slate-coloured” morph Dark-eyed Juncos. Twenty-four visitors were at the site today.

Monday, March 25 Beaver Mines [Day 23] 0730-2000 (Peter Sherrington, assisted by Hilary Atkinson). The temperature at 0730 was -3C, the high was 10.5C at 1500 and it was 6C at 2000. Winds were W-WSW 20-40 gusting to 55 km/h to 1700 after which they were WNW15-25 km/h and became light after 1900. Yesterday’s fog persisted to 0730 when the top of the hill became visible but by 1800 it was completely clear. Cloud cover was 10-40% cumulus to 1300, 80-100% altostratus and cumulus to 1500, 20-60% altocumulus, cumulus and cirrostratus to 1800 and 100% cirrostratus for the rest of the day, all of which gave excellent observing conditions. There was a moderately strong raptor movement of 86 birds of 5 species between 0901 and 1859 which was the highest count so far this season. The flight comprised 20 Bald Eagles (15a, 3sa, 2j), 1 adult male Northern Harrier, a season-high 3 Northern Goshawks (1a, 2u), 1 adult dark morph harlani Red-tailed Hawk and a season-high 61 adult Golden Eagles. Most birds soared high above the ridge, sometimes for extended periods, before gliding high to the N or NW. Movement was often sporadic with several raptor-free periods and the highest hourly count was 15 between 1100 and 1200 and again between 1400 and 1500. Ten Golden Eagles moved between 1806 and 1859. Other birds seen were 9 Canada Geese, 1 male Common Merganser that flew high to the NE at 1905. 27 Wild Turkeys, 12 Rock Pigeons, 3 Downy Woodpeckers, 1 Northern Flicker, 1 Pileated Woodpecker, 2 Blue Jays, 5 Black-billed Magpies, 7 American Crows, 55 Common Ravens 35 of which flew high to the SW to roost between 1700 and 1909, 3 American Robins, 50 European Starlings, 20 Evening Grosbeaks, 70 Grey-crowned Rosy-Finches that flew high to the north in 2 flocks at 1217 and 1558, and 2 Pine Siskins.

Monday, March 25 Steeples [Day 20] 1645-1845 (Vance Mattson). Teaching commitments again restricted observation to the late afternoon when the temperature was 12C, conditions were calm and cloud cover was 80% thin altostratus, altocumulus and cirrus. A total of 9 Golden Eagles (6a, 2j, 1u) migrated between 1652 and 1718. A resident Golden Eagle soared low in the gap and a non-migrant juvenile Bald Eagle soared high over the ridge and then high over Mount Bill Nye to the south. It was rainy and overcast in the morning but the mountains were clear by 1300 so it is probable that several birds migrated before 1645.
