Thursday, November 01 Mount Lorette [Day 39] 0830-1815 (Joel Duncan, assisted by Lori Anderson). The starting temperature was 0C the high was 4C from 1400-1700 and it was 3C at the end of observation. Ground winds were E-NE 2-5 km/h to 1500 after which they were 4-8 occasionally gusting to 14 km/h, while ridge winds were SW all day, strong to 1600 and then moderate. Cloud cover was initially 80% stratus and cumulus which reduced to 20-30% between 1000 and 1200 and gradually increased throughout the afternoon to 80% cumulus, altocumulus and altostratus by the end. The eastern ridges were initially 40% obscured but were clear after 1000, and the west was initially 100% obscured that dropped to 20% at 1000 and was then clear for the rest of the day. There was 0.5 cm of fresh snow on the ground at the start but there was no further precipitation. A total of 16 eagles were seen between 1145 and 1720 that comprised 2 adult Bald Eagles, 13 Golden Eagles (6a, 3sa, 4u) and 1 unidentified eagle. All birds moved on the eastern route with most birds initially located at the northern end of the Fisher Range and most birds employed flapping flight. Maximum hourly counts were 4 from 1500 to 1600 and again from 1600 to 1700. A non-migrant adult Bald Eagle perched by the river and a resident adult Northern Goshawk soared above the Hay Meadow. Other birds seen were 1 Northern Flicker, 20 Bohemian Waxwings, a single flock of 200 Grey-crowned Rosy-Finches, 5 White-winged Crossbills, a remarkable single flock of 23 Cassin’s Finches, 30 Common Redpolls which were the first of the season and 2 Swamp Sparrows. There were 7 visitors today.

Thursday, November 01 Vicki Ridge [Day 36] 0815-1745 (Peter Sherrington, assisted by Gord Petersen observing from the Waterton 61 wellsite. The temperature at 0830 was 0C and the high was 5C at 1700 and 1745. Winds were calm or light all day, SW-W to 1600 and then ESE for the rest of the day. Cloud cover was 100-70% generally thin cumulus, stratocumulus and altostratus that allowed hazy sunshine to 1330 when 100% dark stratocumulus moved from the west and gave gloomy conditions for the rest of the day. The calm conditions produced the lowest full-day count of the season with only 15 birds of 2 species seen between 1044 and 1730: 10 Rough-legged Hawks (8 light morphs, 2u) and 5 Golden Eagles (4a, 1sa). By 1600 only 7 birds had been counted but each of the final 2 hours produced 4 birds that were seen soaring to the south of the site after they had glided low from behind the east side of Vicki Ridge. Gord watched at the western edge of Kyllo Ridge near the Waterton 68 wellsite between 1355 and 1520 but only saw a single Rough-legged Hawk that had also been observed soaring over the eastern edge of Kyllo Ridge a couple of minutes earlier. A mixed flock of 12a Tundra and 2a Trumpeter Swans flew high to the west at 1737 and a flock of 50 Canada Geese flew high to the west at 1225. At 1325 a high-flying adult Northern Shrike selected a single Grey-crowned Rosy-Finch from a small flock and pursued it to the north and had almost caught up with it when both birds disappeared behind trees. Other birds seen included 8 Clark’s Nutcrackers, 120 Bohemian Waxwings, 245 Grey-crowned Rosy-Finches, 3 Red Crossbills and 193 Pine Siskins.

Thursday, November 01 Steeples [Day 38] 1200-1730 (Vance Mattson). The temperature was 6C, conditions were calm and cloud cover was 100% altostratus and dark grey cumulus that obscured the front face of Mount Bill Nye, but the main migration ridge remained clear. Just 2 migrants were noted: an adult Golden Eagle at 1332 and an adult Bald eagle at 1338, and no resident birds were seen.

5.5 hours (165.3) BAEA 1 (92), GOEA 1 (145) TOTAL 2 (427)

 

Friday, November 02 Mount Lorette [Day 40] 0900-1830 (Caroline Lambert, assisted by Joel Duncan). The temperature at 0900 was 5C, the high at 1400 was 10C and it was 4C at 1830. Ground winds were SW 0-5 km/h to 1200 then variable gusting to 20 km/h to 1400 after which they were N 0-10 gusting 20 for the rest of the day; ridge winds were strong all day, SW to 1000, NW to 1500 and NNW to the end. Cloud cover was 80-100% mainly cumulus and altostratus all day that produced 20-minute light rain showers around 1500 and 1600. The eastern ridges were occasionally lightly draped by cloud, but the west was on average 40% obscured all day. A total of 18 migrants of 3 species moved between 1022 and 1752 comprising 1u Bald Eagle, 1u Northern Goshawk and 16 Golden Eagles (5a, 2sa, 1j, 8u). All eagles glided high above the Fisher Range and probably originated from Mount Lorette. Ten birds, all Golden Eagles, were seen before 1200 but afternoon movement was slow and sporadic. An adult Bald Eagle perched on its usual tree by the river, and 2u Northern Goshawks flying high to the west were considered resident. Three unidentified swans flew high towards the north, 3 Common Loons flew high to the south and other birds seen included 1u Northern Shrike, 1 Brown Creeper, 1 Golden-crowned Kinglet, 2 Bohemian Waxwings, 15 White-winged Crossbills, 2 Pine Siskins, and 10 Dark-eyed Juncos that included 2 cismontanus (“Slate-coloured” morphs) and 2 montanus (“Oregon” morphs). Only 4 visitors were seen today.

Friday, November 02 Vicki Ridge [Day 37] 1140-1800 (Peter Sherrington, assisted by Hilary Atkinson observing from the Waterton 61 wellsite). It was a late start as we had to drive back from Calgary. At 1140 the temperature was 8C, the high was 8.5C at 1300 and 1400 and it fell to 5C at 1800. Winds were strong W 40-50 gusting to 80 km/h to 1600 when they moderated and at the end of the day they were light SSE. Cloud cover was 70% altostratus and cumulus that gave sunny periods to 1400 after which it was 100% stratocumulus that produced almost continuous very light rain that only became steady light rain at 1800. There was a fairly steady movement of 39 raptors of 3 species between 1203 and 1746 that comprised 16 Bald Eagles (10a, 1sa, 3j, 1 undifferentiated immature and 1u), 6 Rough-legged Hawks (4 light, 2u) and 17 Golden Eagles (15a, 1sa, 1u). The highest hourly counts were 11 (1300-1400) and 10 (1500-1700). Other birds were relatively scarce in the high winds but included 1 Pileated Woodpecker, 1 Clark’s Nutcracker, 37 Bohemian Waxwings, 100 Grey-crowned Rosy-Finches and 32 Pine Siskins.

6.33 hours (333.4) BAEA 16 (330), RLHA 6 (418), GOEA 17 (2512) TOTAL 39 (4376)

 

Friday, November 02 Steeples [Day 39] 1315-1800 (Vance Mattson). The morning was rainy and overcast but it began to clear at 1230 although the front face of Mount Bill Nye again remained obscured all day. On arrival the temperature was 12C, winds were moderate S and cloud cover was stratus and cumulus, but by 1600 conditions were calm and 40% cumulus and lenticular cloud cover gave mainly sunny conditions for the rest of the day. A total of 4 migrant Golden Eagles were seen: 2 adults migrating together at 1612 and adult and a juvenile that also migrated together at 1612. The juvenile’s two outer left retrices had been somehow shorn off in a clean line that gave the tail a paddle-like appearance. A non-migrant adult Bald Eagle soared high above the ridges and moved to the north at 1559.

Tuesday, October 30 Mount Lorette [Day 37] 0830-1830 (Cliff Hansen, assisted by Brian McBride). The temperature reached a high of 6C at 1500 and 1600 from a morning low of -1C and it was 4C at 1830. Ground winds were SW all day, 0-10 gusting to 15 km/h in the afternoon and ridge winds appeared to be moderate NW. Cloud cover was 70-50% cumulus and altocumulus all day apart from 1240-1310 when a light snow squall obscured the sky and ridges which otherwise were clear all day. Observing conditions were good but the day only produced 13 migrant raptors between 1053 and 1640 which is the lowest count for a non-weather affected day since October 3. The count was 3 light morph Rough-legged Hawks, 9 adult Golden Eagles and 1 unidentified eagle. All the eagles glided high above the Fisher Range and 6 of the birds were seen between 1500 and 1600. A resident adult male Northern Goshawk was seen hunting near the site at 1532. Other birds seen were 2 Belted Kingfishers that flew to the south about 30 metres above the river around 1300 that may have been migrating, 1 adult Northern Shrike, 3 American Robins flying south and a small flock of 4 cismontanus Dark-eyed Juncos. There were 6 visitors to the site today.

Tuesday, October 30 Vicki Ridge [Day 34] 0815-1800 (Peter Sherrington, observing from the Waterton 61 wellsite). The temperature at 0815 was 0.5C, the high at 1400 was 8C and it was 3C at 1800. Winds were W and were a remarkably constant 30-40 gusting 50 km/h all day. Cloud cover was 80-90% cirrostratus and altocumulus to 0900 which diminished to 0% at 1300, after which it was 10-20% cumulus and cirrus that was essentially confined to the west. There was a fairly reasonable, although rather sporadic, raptor migration with 70 birds of 7 species moving between 0821 and 1721. The count was 25 Bald Eagles (12a, 5sa, 6j, 1 undifferentiated immature and 1u), 2 adult Sharp-shinned Hawks, 1 adult Cooper’s Hawk, 7 adult Northern Goshawks (6 males, 1 female), 1 adult dark morph harlani Red-tailed Hawk, 9 light morph Rough-legged Hawks and 25 Golden Eagles (21a, 1j, 3u). The highest hourly count was 14 between 1400 and 1500 that included 9 Bald and 4 Golden Eagles. The 3 Bald Eagles that were seen at 1429 moved the cumulative total species count above the previous fall site record of 4237 that was established on November 15 last year. Other bird sightings included 4 Trumpeter Swans (3a, 1j) that flew to the WNW over Kyllo Ridge at 0943, 8 Clark’s Nutcrackers, 56 Bohemian Waxwings flying south in 3 flocks, 200 Grey-crowned Rosy-Finches in 7 flocks, 7 Red Crossbills and 24 Pine Siskins.

Monday, October 29 Mount Lorette [Day 36] 0740-1830 (George Halmazna, assisted by Dan Parliament). The starting temperature was 0C the high was 5.5C at 1600 and it was 3.5C at the end of observation. Ground winds were SW mainly light but gusted to 15 km/h between 1000 and 1200, and ridge winds were SW also light and occasionally moderate in the afternoon. Cloud cover was mainly cumulus all day, 30% to 1200 and 90-70% in the afternoon which provided good observing conditions, and the ridges were all clear. A total of 36 migrants of 3 species were seen between 0932 and 1742 of which 32 were Golden Eagles (21a, 1sa, 3j, 7u): the other birds were 1 juvenile Bald Eagle and 3 Northern Goshawks (2a, 1u). The maximum hourly count was 1600-1700 which saw the passage of 7 Golden Eagles. All movement was along the Fisher Range mainly at ridge level and only the last 5 eagles after 1700 glided high above the ridge. Other birds included 3 Ruffed Grouse, 50 Bohemian Waxwings in 2 flocks, 52 Grey-crowned Rosy-Finches, 11 White-winged Crossbills, 2 Evening Grosbeaks and 31 Pine Siskins. The highlight of the day, however, was a Bobcat that was seen and photographed early in the morning near the site. The animal is rare in the Kananaskis Valley. The 5 visitors today were particularly welcome as they brought baked goods for the observers!

Monday, October 29 Vicki Ridge [Day 33] 0815-1840 (Peter Sherrington, observing from the Waterton 61 wellsite and Gord Petersen observing from the Waterton 68 wellsite, 1340-1745). The temperature at 0815 was 2C the high at 1600 was 6C and it was 4C at 1815. Winds were W-WSW all day, 15-20 km/h to 1100 then 25-35 gusting to 45 km/h for the rest of the day. Cloud cover was 70-100% altostratus, altocumulus, cumulus and cirrus all day that provided a spectacular sunrise and sunset and excellent viewing conditions throughout. There was a fairly strong and persistent raptor movement throughout the day with 126 migrants of 8 species seen between 0825 and 1806. The count was the highest since October 20 and the diversity was highest since October 18. The count comprised a season-high 32 Bald Eagles (19a, 5sa, 6j, 2u), 1 adult male Northern Harrier, 4u Sharp-shinned Hawks, 1u Cooper’s Hawk, 4 Northern Goshawks (3a, 1j), 1 adult light morph calurus Red-tailed Hawk, 42 Rough-legged Hawks (32 light, 7 dark, 3u) and 41 Golden Eagles (36a, 3j, 2u). The total includes 35 migrants seen by Gord Petersen between 1340 and 1745 at the western edge of Kyllo Ridge near the Waterton 68 wellsite that comprised 9 Bald Eagles (5a, 4sa), 1u Sharp-shinned Hawk, 1u Cooper’s Hawk, 3 Northern Goshawks (2a, 1j), 16 Rough-legged Hawks (9 light, 5 dark, 2u) and 5 adult Golden Eagles.

Sunday, October 28 Mount Lorette [Day 35] 0725-1830 (Bill Wilson, assisted by Cliff Hansen). The temperature at 0725 was 2C, the high at 1600 was 9C and it was 6C at 1830. Ground winds were SW 2-10 gusting 25 km/h and ridge winds were SW all day, moderate to 1100 and then strong. Cloud cover was 100% stratus to 1100 then 40-90% cumulus for the rest of the day with the exception of 1600 when it briefly thinned to 10%. Moderate rain and sleet fell between 0930 and 1030 that completely obscured the Fisher Range that was otherwise 10-30% obscured to 1100. The west was 70-100% obscured to 1100 and was then variably 10-90% obscured for the rest of the day. The first migrant was not seen until 1242, but the final count was 52 raptors of 4 species with the last 2 Golden Eagles moving at the relatively early time of 1608. The count was 8 Bald Eagles (6a, 1sa, 1j), 1 juvenile Sharp-shinned Hawk, 2 Rough-legged Hawks (1 light, 1u) and 43 Golden Eagles (34a, 5j, 4u). All the birds used the eastern route with most eagles gliding high above the Fisher Range, and the maximum hourly count was 17, including 15 Golden Eagles, between 1500 and 1600. Other birds were 1 Mallard flying to the south high above the Fisher Range, 2 female Common Mergansers, 1 Northern Shrike, 4 Canada Jays, 5 Rusty Blackbirds, 85 White-winged Crossbills and 2 Pine Siskins. There were 23 visitors at the site today.

Sunday, October 28 Vicki Ridge [Day 32] 0845-1805 (Peter Sherrington, observing from the Waterton 61 wellsite and Gord Petersen observing from the Waterton 68 wellsite, 1545-1745). The temperature at the start was 2C, the high was 9C at 1600 and it was 6C at the end. Winds were W-WSW all day, light to 1100 and strong thereafter gusting 60-70 km/h in the middle of the afternoon and were still 40-50 km/h for the last two hours. Cloud cover was 100% stratus and cumulus to 1300 that produced steady moderate and sometimes heavy rain to 1110, although the ridges remained clear. The cloud cover began to break at 1300 and was 90-80% altostratus, cumulus and cirrus to 1430 when it thinned to 20-40% cumulus, altostratus and cirrus until 1800 when it increased to 70%. Once the rain ceased a total of 52 migrant raptors of 6 species were seen between 1128 and 1745 comprising 16 Bald Eagles (11a, 4sa, 1j), 1u Sharp-shinned Hawk, 4 adult Northern Goshawks (3 male, 1 female), 13 Rough-legged Hawks (9 light, 3 dark, 1u), 17 Golden Eagles (11a, 3sa, 2j, 1u) and 1u male Prairie Falcon. The total includes 16 migrants seen by Gord Petersen between 1545 and 1745 at the western edge of Kyllo Ridge near the Waterton 68 wellsite that comprised 7 Bald Eagles (6a, 1sa), 1u Sharp-shinned Hawk, 2 Rough-legged Hawks (1 light, 1 dark) and 6 Golden Eagles (3a, 2sa, 1j). Twenty-five of the birds moved between 1606 and 1745. Between 1021 and 1042 a non-migrant Rough-legged Hawk hunted by hovering and planing above Vicki Ridge in steady moderate rain but only made one (unsuccessful) vertical stoop. At 1042 a raven soared low beneath it and the hawk immediately flew to the east of the ridge and out of sight. Migrant finches were 430 Grey-crowned Rosy-finches in 4 flocks and 80 Pine Siskins in 2 flocks.

Sunday, October 28 Steeples [Day 33] 1330-1730 (Vance Mattson). The mountain ridges were heavily obscured although the valley began to clear at 1300. Vance observed from the balcony of his house in Wasa where the temperature reached 11C, conditions were calm and cloud cover was 60% stratus and cumulus that brought rain showers between 1420 and 1500. The only migrant seen was a juvenile Bald Eagle at 1403.

Saturday, October 27 Mount Lorette [Day 34] 0845-1815 (Blake Weis, assisted by Rosemary). The temperature at 0845 was 3C the high was 7C (1400-1700) and it was 5C at 1815. Ground winds were SSW all day 3-10 gusting 20-30 km/h and ridge winds were strong SW-WSW all day. Cloud cover was initially 20% altocumulus that increased to 60% at 1200, decreased to 20% altocumulus and cirrus at 1500 after which it was 30% cirrus and altocumulus for the rest of the day. The first bird of the day was an adult Peregrine Falcon at 1131 that crossed the Kananaskis Valley from the summit of Mount Lorette to the northern end of the Fisher Range in about 30 seconds. Unfortunately, the rest of the day up to 1744 only produced another 18 migrants that comprised 2 adult Bald Eagles, 15 Golden Eagles (12a, 1j, 2u) and 1 unidentified eagle. Seven of the Golden Eagles moved between 1500 and 1600. Most of the birds were initially located at the northern end of the Fisher Range and most glided fairly high above the ridge. Other birds flying to the south were a flock of 25 Canada Geese, 1 Clark’s Nutcracker, 20 Bohemian Waxwings, 40 White-winged Crossbills and 35 Pine Siskins. There were 15 visitors at the site today.

Saturday, October 27 Vicki Ridge [Day 31] 0845-1800 (Peter Sherrington, observing from the Waterton 61 wellsite). The starting temperature was 4C the high at 1600 was 10C and it was 6C at 1800. Winds were W-WSW all day, 10-15 km/h to 0930 then 30-40 gusting 50-70 km/h for the rest of the day. It was cloudless to 1530 when traces of cirrus and cumulus began to develop that became 30% cirrus at 1700 and 100% thin cirrostratus and altocumulus at 1800. Today’s count was 64 raptors of 5 species that moved between 0907 and 1748 which comprised 15 Bald Eagles (12a, 1sa, 2u), 3 adult Northern Goshawks, 2 adult Red-tailed Hawks (1 light calurus and 1 dark harlani) that soared together above Vicki Ridge at 1531 and brought the season’s total raptor count to 4000, 14 Rough-legged Hawks (11 light, 1 dark, 2u) and 30 Golden Eagles (23a, 2sa, 4j, 1u). Thirty-six migrants, including 26 Golden Eagles, were counted before 1200 and a significant migration appeared to be in the offing, but the next 3 hours yielded only 7 birds before a slight recovery saw the movement of 21 more raptors between 1510 and 1748. Other birds seen included a large adult white-headed gull (probably a Herring Gull) that flew high to the west from the northern end of Kyllo Ridge at 1531, 6 Clark’s Nutcrackers, 1 American Robin, 271 Grey-crowned Rosy-Finches that flew to the south in 6 flocks, 15 Red Crossbills and 10 Pine Siskins.
