RMERF counts, October 10
Wednesday, October 10 Mount Lorette [Day 17] 0710-1920 (Caroline Lambert, assisted by Joel Duncan). The temperature was initially -7C, the high was 1C from 1400 to 1900 and it was 0C on departure. Ground winds were variable and light to 1400, NE 5-10 gusting 20 km/h to 1600 then N 0-5 gusting 15 km/h for the rest of the day.; ridge winds were light S to 1100, light west to 1400 after which they were moderate. Cloud cover was initially 50% altocumulus and altostratus that reduced to 20% cumulus and cirrocumulus at 1200-1500, and was then 100% stratus for the rest of the day. There were light snow flurries after 1600. The only migrant raptors were 8 Golden Eagles (4a, 1sa, 1j, 2u) that moved between 1250 and 1430, 6 of which occurred between 1400 and 1430. All birds moved on the eastern route with much soaring and flapping flight. A single adult resident Golden Eagle flew to the east from Hummingbird Plume Hill to beyond the Fisher Range ridge. The Sora was still present and other birds included 1 Belted Kingfisher, 1 Brown Creeper, 2 American Dippers, 10 Golden-crowned Kinglets, 3 American Pipits, 20 White-winged Crossbills, 6 Pine Siskins, 4 Lapland Longspurs, 8 cismontanus Dark-eyed Juncos, 2 White-throated Sparrows 1 male Rusty Blackbird and 1 Yellow-rumped Warbler.

Wednesday, October 10 Vicki Ridge [Day 14] 1045-1715 (Peter Sherrington, observation from Waterton 61 wellsite). The snow finally stopped around 1000 and there was 6cm of fresh snow at the site. The temperature was -4C at 1100, rose to a high of -2 C at 1500 and was -3C at the end of observation. Winds were light SE-E all day and cloud cover was 100% stratus that was only occasionally and briefly broken giving gloomy conditions all day. East of the ridge after 1715, however, the skies were clear and it was sunny! There was only a light, sporadic migration of 18 raptors of 5 species between 1110 and 1626 that comprised 8 Sharp-shinned Hawks (4a, 4u), 1a Northern Goshawk, 7 Red-tailed Hawks (4a calurus: 3 light, 1 dark; 3 dark harlani: 2a, 1j), 1u columbarius Merlin and 1 Prairie Falcon. Ten birds moved before 1300 with 6 between 1100 and 1200, but 6 Sharp-shinned Hawks were the only migrants moving after 1330. Other birds included 1 Dusky Grouse, 1 Northern Pygmy-Owl that called briefly, 1 adult Northern Shrike, 5 Clark’s Nutcrackers, 8 American Robins and 8 Red Crossbills

Wednesday, October 10 Steeples [Day 18] 1530-1800 (Vance Mattson). It was a beautiful day with a temperature of 11C and sunny calm conditions with a cloud cover of 30% altostratus and cumulus that increased to 60% altocumulus. Only 2 migrants were seen, however: 1u Sharp-shinned Hawk and 1j Northern Goshawk that flew south together at 1722. The only other raptors were the resident Golden Eagles that interacted above the ridge including a playful stoop that produced a barrel-roll from the other bird followed by a brief display flight by one of the birds. The two then soared together over the flank of Bill Nye Mountain.

RMERF counts, October 9
Tuesday, October 09 Mount Lorette [NO OBSERVATION]. (Cliff Hansen and Rick Robb 0830-1650). The temperature was -4C to -1C, wind was N 5-10 gusting 15 km/h and cloud cover was 100% low stratus that produced light snow and obscured all mountains. The few birds identified were 1 Hairy Woodpecker, 2 Black-billed Magpies, 2 Ruby-crowned Kinglets and 1 Varied Thrush.
Tuesday, October 09 Vicki Ridge [NO OBSERVATION]. The temperature was -4C, winds were E-ENE 15-20 km/h and cloud cover was 100% low stratus that completely obscured the ridge. Light snow fell all day.
Tuesday, October 09 Steeples [Day 17] 1315-1745 (Vance Mattson). The precipitation that was forecast did not arrive although it was a cloudy day with 60-80% cumulus and altostratus, a temperature of 9C and NW and, later in the day, E winds. A total of 11 migrants of 4 species were seen up to 1702 which comprised 3 juvenile Bald Eagles, 3u Sharp-shinned Hawks, 2 Northern Goshawks (1j, 1u) and 3 Golden Eagles (1a, 1j, 1u). Four non-migrant Bald Eagles (3a, 1j) were seen but, unlike the last couple of days, they were not heading north. The last migrant was a juvenile Golden Eagle that soared low at length, then rose very high and joined 6 soaring ravens which immediately set about the eagle that quickly glided to the south after making a brief token rejoinder.

RMERF counts, October 7 and 8
Sunday, October 07 Mount Lorette [Day 16] 0710-1920 (Bill Wilson, assisted by Lori Anderson and Patrick Farley). The temperature at 0800 was -7C, the high was 7C at 1600 and 1700 and it was 1C at 1920. Ground winds were SW all day 5-8 km/h which probably also reflected the ridge winds. There was a trace of altostratus at the start which expanded to 40% at 0900 and was 0-20% for the rest of the day with a trace of cumulus developing at the end of observation. There was a fairly strong raptor migration with 105 birds of 7 species moving between 1046 and 1829 comprising 8 Bald Eagles (1a, 1sa, 6j), 5u Sharp-shinned Hawks, 2 adult Northern Goshawks, 1 small unidentified Accipiter, 1 light morph Rough-legged Hawk, 86 Golden Eagles (41a, 5sa, 29j, 11u), 1u Merlin and 1 adult Peregrine Falcon which was the first for the season. Most of the birds used the eastern route but about 20 of the Golden Eagles were seen to the west. There was much soaring and flapping and gliding flight in the light winds. The highest hourly counts were 23 from 1200 to 1300 and again from 1300 to 1400 and there was a late peak of 14 birds (1 Bald Eagle and 13 Golden Eagles) between 1800 and 1829. Other birds included the Sora that was first reported on October 3, 1 Pileated Woodpecker, 2 Clark’s Nutcrackers, 1 American Dipper and 3 American Pipits. Twenty-six visitors enjoyed both the weather and the birds.

Monday, October 08 Mount Lorette [NO OBSERVATION]. (George Halmazna, assisted by Dan Parliament 0745-1200). The temperature was -2C to -1C, wind was WNW 5-10 km/h and low stratus cloud obscured all the ridges and produced steady snow. Birds seen around the Hay Meadow and at Lorette Ponds included the now apparently “resident” Sora, 1 Varied Thrush, 1 American Dipper, 1 Song Sparrow, 1 Savannah Sparrow, 4 Rusty Blackbirds (3 males, 1 female) and 1 Palm Warbler.
Sunday, October 07 Vicki Ridge [Day 13] 0900-1815 (Peter Sherrington to 1415; Doug and Teresa Dolmen after 1415, observing from the Waterton 61 wellsite). The temperature at 0900 was 0C the high was 9C at 1300 and 1400 and it was 6C at 1815. Winds were NW 3-10 gusting 15 km/h to 1200, and W in the afternoon to 10 km/h. Cloud cover was 0-10% in the morning with trace amounts of altocumulus and cirrus, 30-80% cirrus, cumulus and altocumulus to 1700 and it became almost cloudless again at the end of observation. There was another fairly strong and varied raptor movement of 150 birds of 11 species between 1036 and 1810 that comprised 7 Bald Eagles (5a, 2sa), 15 Sharp-shinned Hawks (3a, 1j, 11u), 5 Cooper’s Hawks (1a, 4u), 1 adult Northern Goshawk, 1 unidentified small Accipiter, 3 light morph Broad-winged Hawks (1a, 2u), 11 Red-tailed Hawks (calurus 9 : 4a, 1j light, 4a dark, and 2 dark harlani: 1a, 1j), 3 Ferruginous Hawks (1j light morph and 2a dark morphs), 2 light morph Rough-legged Hawks, 7 unidentified Buteos (1 light, 4 dark, 2u), 94 Golden Eagles (38a, 13sa, 30j, 13u) and 1u columbarius Merlin.

Monday, October 08 Vicki Ridge [NO OBSERVATION]. Ridges obscured all day by low cloud to 1100 and dense fog with light rain thereafter.
Sunday, October 07 Steeples [Day 15] 1145-1845 (Vance Mattson, assisted by Joe Rothermund, Dianne Cooper and Virginia Rasch). The temperature was 10C, winds were calm to light variable, and cloud cover was 10% cumulus. A total of 22 migrants of 4 species were counted between 1258 and 1801 comprising 4 Bald Eagles (3a, 1j), 11 Sharp-shinned Hawks (6a, 5u), 4 Red-tailed Hawks (2j light morph calurus Red-tailed Hawks and 2 (1a, 1j) dark morph harlani (1a, 1j)), and 3 Golden Eagles (2a, 1sa). Many migrants appeared from behind the main ridge and were difficult to spot in the blue sky and the presence of 3 other observers was a great help. Resident Golden Eagles were seen on 2 occasions, and 13 non-migrant Bald Eagles (8a, 4j, 1u), 11 of which moved to the north along the ridge including a group of 6 at 1641.

Saturday, October 06 Mount Lorette [Day 15] 0800-1900 (Blake Weis, assisted by Ruth Morrow and Patrick Farley). The temperature was -8C at 0800, the high was 6C from 1600 to 1800 and it was -1C at 1900. Ground winds were light all day, variable 0-3 km/h to 1000, SSW 0-5 gusting 10 km/h to 1300, SSW and occasionally E to 1800 and SSW 0-5 km/h for the last hour; ridge winds were probably light to moderate SSW. It was essentially cloudless all day with only traces of cirrus and altocumulus cloud. There was another strong raptor movement again dominated by Golden Eagles with 209 birds of 7 species migrating between 1055 and 1907. The flight comprised a season-high 13 Bald Eagles (6a, 2sa, 5j), 5u Sharp-shinned Hawks, 1a Northern Goshawk, 2 small unidentified Accipiters, 1a light morph calurus Red-tailed Hawk, 1 dark morph Rough-legged Hawk, 182 Golden Eagles (91a, 6sa, 69j 16u), 1 unidentified eagle, the season’s first Gyrfalcon, a probable female grey morph that briefly harassed a juvenile Golden Eagle as it flew south, and 2 small unidentified raptors. With the exception of one Sharp-shinned Hawk, all birds were seen on the eastern route with most migrants flapping low in front of the face of the Fisher Range. Peak movement was 53 raptors between 1300 and 1400 that included 46 Golden Eagles. Non-migrants were a Sharp-shinned Hawk that hunted American Pipits along the river in the morning and a Merlin that perched near the site at 1815. Other birds near the site were 1 American Dipper, 1 Varied Thrush, 1 American Robin, 1 Ruby-crowned Kinglet, 4 Golden-crowned Kinglets, 25 American Pipits, 5 White-winged Crossbills, 1 Lincoln’s Sparrow, 1 Song Sparrow, 1 White-crowned Sparrow of the race gambelii which was found dead, having probably perished in the recent snow storm, 7 Dark-eyed Juncos, 2 Yellow Warblers and a late migrating Common Yellowthroat. A Mountain Goat spent some time high on the ridge at the northern end of the Fisher Range, and there were 24 visitors at the site today.

Saturday, October 06 Vicki Ridge [Day 12] 0900-1730 (Peter Sherrington, assisted by Hilary Atkinson observing from the Waterton 61 wellsite). The temperature at 0900 was -2C the high at 1200 was 7C and it was 5C at 1730. Winds were light all day (< 8 km/h), variable to 1200 then E for the rest of the day, but there was probably a light westerly flow above Kyllo Ridge to the west of Vicki Ridge. Cloud cover was 0-10% cirrostratus to 1200 after which scattered cumulus developed that reached 20% at 1400 and 1500 after which it was again cloudless with trace cumulus and cirrus cloud. The only raptor seen in the morning was a female columbarius Merlin at 1013 which briefly perched on a snag on the flank of Vicki Ridge before flying low to the south. This proved to be the only bird seen on Vicki Ridge all day with the remaining 233 migrant raptors soaring high and gliding high to the south between 1223 and 1706 on a broad front between the centre of the valley and the western edge of Kyllo Ridge. The final count of a season-high 234 birds of 9 species was 6 Bald Eagles (2a, 2sa, 2j), 11u Sharp-shinned Hawks, 2 Cooper’s Hawks (1a, 1u), 2 Northern Goshawks (1a, 1u), 1u dark morph Broad-winged Hawk, 19 Red-tailed Hawks (16 calurus: 7a, 5u light morphs, 3a, 1u dark morphs; 1a dark harlani, and 2 undifferentiated dark morphs), 7 Rough-legged Hawks (5 light, 1 dark, 1u), 8 unidentified Buteos (7 dark, 1u), a season-high 175 Golden Eagles (78a, 14sa, 46j, 37u), 1 female columbarius Merlin and 2 small unidentified raptors. There was much high soaring flight with the largest kettles of Golden Eagles being 14 at 1409 and 16 at 1519. The busiest hour was 1500-1600 with 70 migrants including 63 Golden Eagles and 1400-1500 saw 60 birds move of which 46 were Golden Eagles. Other birds were scarce and included 1 male Pileated Woodpecker, 2 Blue Jays, 3 Clark’s Nutcrackers, 3 American Robins, 5 Red Crossbills and 16 Pine Siskins.

Saturday, October 06 Steeples [Day 14] 1200-1900 (Vance Mattson). The temperature was 9C at 1200, reached a high of 10C before dropping to 7C at 1900, winds were light to moderate N-NW and cloud cover was 20-40% cumulus which provided both sunshine and excellent observing conditions. The mountains finally cleared and there was a strong raptor movement of 104 birds of 6 species between 1229 and 1840 that comprised 14 Bald Eagles (9a, 3sa, 2j), 2 Northern Harriers (1a female, 1u), 9 Sharp-shinned Hawks (4a, 5u), 1a Northern Goshawk which was the first for the season, 3 calurus Red-tailed Hawks (2a light, 1u dark) and a season-high 75 Golden Eagles (55a, 20j). Both the total and the Golden Eagle count were site records for fall counts. The highest hourly counts were 29 (including 23 Golden Eagles) between 1400 and 1500, 24 (18 Golden Eagles 1500-1600 and 19 (18 Golden Eagles) 1700-1800. Most migrants moved close to the ridges and the flight was initially very fast but became slower as the day progressed. Resident Golden Eagles were seen on 3 occasions and 14 non-migratory Bald Eagles were seen including many that moved along the ridges towards the north.

Cloud cover was 60% altocumulus and cirrus that became cumulus and cirrus at 1400 and reduced to 20% after 1500. The ridges were clear all day. There was a fairly strong raptor movement of 125 migrants of 5 species between 1125 and 1923 that included the highest Golden Eagle count of the season. The count was 2 Bald Eagles (1a, 1j), 7 Sharp-shinned Hawks (5a, 2u), the first Swainson’s Hawk of the season, a light morph adult, 1 adult rufous morph calurus Red-tailed Hawk, and 124 Golden Eagles (16a, 2sa, 71j, 35u). Golden Eagle movement was increasingly strong from mid-afternoon with hourly counts of 21 (15-1600), 18 (16-1700), 25 (17-1800), 32 (18-1900) and 12 (19-1923). Only a few Golden Eagles were located over Mount Lorette and they appeared originate from Heart Mountain farther to the north, from where they crossed Wasootch Creek and flapped low to the SE in front of the Fisher Range, although there was some soaring flight between 1400 and 1700. [NOTE: the low adult and subadult counts and the high count of juvenile birds are anomalous compared to the Vicki Ridge count of October 5 and the Lorette count of October 6]. Other birds seen were 1 Hairy Woodpecker, 4 Common Ravens, 2 Golden-crowned Kinglets, 3 Ruby-crowned Kinglets, 1 Swainson’s Thrush, 1 Varied Thrush, 2 American Robins, 2 American Pipits, 1 Song Sparrow and 6 White-winged Crossbills. Many of the birds were seen feeding at the river’s edge on newly emerged stoneflies. Looking distinctly out of place in the snowy landscape was a single Mourning Cloak butterfly on the wing. There were 5 visitors to the site today.

Thursday, October 04 Vicki Ridge [Day 10] 0930-1745 (Peter Sherrington, assisted by Hilary Atkinson observing from the Lynx Creek road). The starting temperature was -5C, the high was 1C at 1600 and it was -2C at 1745. Winds were light all day, WSW to 1030 and subsequently E 4-10 km/h. Cloud cover was 100% stratus that became 100% altostratus, cirrostratus, altocumulus and cumulus after 1500 that produced hazy sunshine all day. There was another fairly strong and varied raptor migration with 107 birds of 12 species moving between 1044 and 1733. The flight comprised 2 Ospreys, 4 Bald Eagles (2sa, 2j), 1 adult male Northern Harrier, 61 Sharp-shinned Hawks (1a, 60u), 10u Cooper’s Hawks, 3 Northern Goshawks (1a, 2u), 3 small unidentified Accipiters, 3 Red-tailed Hawks (2 calurus: 1u light, 1 dark adult, and 1 adult dark harlani), 1 light morph Rough-legged Hawk, 1 unidentified dark Buteo, 12 Golden Eagles (9a, 3j), 1u American Kestrel, 2 columbarius Merlins (1 female, 1u), 1u Peregrine Falcon, 1 large unidentified falcon and 1 small unidentified raptor. Fifty of the birds moved between 1300 and 1500.

Thursday, October 04 Steeples [Day 12] 1300-1900 (Vance Mattson). The entire valley was enshrouded in low cloud which began to clear at 1300 but the mountains remained enveloped so Vance conducted the count from the balcony of his house in Wasa. The temperature was 6C, winds were calm or light W and cloud cover was 100-70% altocumulus, cumulus and altostratus; the mountains remained 90-100% obscured throughout. A season high total of 66 raptors of 10 species migrated between 1332 and 1812 comprising 2 Ospreys, 11 Bald Eagles (5a, 5j), 2 Northern Harriers (1 adult female, 1 juvenile), 11 Sharp-shinned Hawks (3a, 1j, 7u), 2 Cooper’s Hawks (1a, 1j), a season-high 28 Red-tailed Hawks (24 calurus: 20a (19 light, 1 dark), 1 light juvenile, 1 rufous juvenile and 2 unaged; 1j dark morph harlani and 3 birds of unknown race, morph or age), 1 light morph Rough-legged Hawk, 6 Golden Eagles (3a, 3j) 1 unidentified eagle, 1 female American Kestrel and 1u columbarius Merlin. About 90% of the birds moved over or just east of Wasa Lake and the highest hourly counts were 17 from 1600 to1700 and again from 1700-1800. There was also a strong movement of 147 American Crows including flocks of 28 and 40 birds, and 5 California Gulls also moved to the south.

Friday, October 05 Mount Lorette [Day 14] 0800-1900 (Caroline Lambert, assisted by Rosemary). The temperature at 0800 was -11C but reached a high of 3C at 1600 and 1700 and was -1C at the end of observation. Ground winds were SW 0-5 km/h all day, and ridge winds were moderate, SW to 1700 then W. Cloud cover was 60% cirrus and cirrostratus to 1000 then 60-100% altostratus with minor cumulus for the rest of the day; the ridges were completely clear. There was a strong raptor movement dominated by Golden Eagles with a season high 349 birds of 6 species moving between 0904 and 1846. The count was 3 Bald Eagles (2sa, 1j), 1u Sharp-shinned Hawk, 1u Northern Goshawk, 1u light morph Red-tailed Hawk, 1 unidentified Buteo, a season high 337 Golden Eagles (207a, 29sa, 51j, 50u), 3 unidentified eagles, 1 female columbarius Merlin and 1 unidentified raptor. All the eagles moved mainly close the Fisher Range ridge, but as relatively few birds were seen leaving Mount Lorette it is probable that most of the birds, as yesterday, originated from Heart Mountain. Golden Eagle movement was strong all day and peaked at 62 birds between 1400 and 1500 and 6 other hours produced over 30 migrants, Other birds included 1 Sora, presumably the bird reported a couple of days ago, 6 Golden-crowned Kinglets, 10 American Robins, 1 American Pipit, the first Pine Grosbeak of the season, 50 Grey-crowned Rosy-Finches, 6 White-winged Crossbills, 2 Pine Siskins, 1 Song Sparrow, 1 Lincoln’s Sparrow, 1 Orange-crowned Warbler and 1 Yellow-rumped Warbler. Seventeen visitors to the site enjoyed the spectacular eagle movement.

Friday, October 05 Vicki Ridge [Day 11] 0900-1800 (Peter Sherrington, assisted by Hilary Atkinson, Denise Cocciolone-Amatto, Pat Lucas and Trevor Lewis, observing from the Waterton 61 wellsite). The temperature at 0900 was -1C, the high was 6C at 1500 and it was 4.5C at 1800. Winds were WNW 20-25 km/h to 1000 and were then W 20-35 gusting 55 km/h that dropped to 15-20 km/h after 1630. It was initially cloudless but cirrus and altocumulus cloud rapidly developed after 1000 and was 100% mainly altostratus and altocumulus cloud after 1200 which produced gloomy conditions for much of the afternoon. A season high 205 raptors of 8 species were seen between 0908 and 1744 that comprised 2a Bald Eagles, 49 Sharp-shinned Hawks (9a, 40u), 3 Cooper’s Hawks (1a, 2u), 3a Northern Goshawks, 14 a Red-tailed Hawks (12 calurus: 10 light, 2 dark and 2 dark harlani), 7 Rough-legged Hawks (6 light, 1 dark), a season-high 126 Golden Eagles (78a, 14sa, 34j) and 1 adult male Peregrine Falcon. Peak moment was 53 raptors between 1400 and 1500 and the maximum Golden Eagle passage was 36 between 1300 and 1400. Only 3 birds moved after 1700. Other birds seen included 5 Clark’s Nutcrackers, 11 Mountain Bluebirds, 10 American Robins, 40 Bohemian Waxwings, 25 Grey-crowned Rosy-Finches, 5 Red Crossbills and 27 Pine Siskins.

Friday, October 05 Steeples [Day 13] 1330-1800 (Vance Mattson). Weather conditions were similar to those of yesterday with the mountains completely obscured, a temperature of 7C, calm and 100% stratus, altostratus and dark cumulus. Observation was again from the balcony of Vance’s house in Wasa from where he counted 15 migrants of 4 species between 1342 and 1548. The count was 8 Bald Eagles 6a, 1sa, 1j), 1a light morph calurus Red-tailed Hawk, 1 dark morph Rough-legged Hawk, 4a Golden Eagles and 1 unidentified eagle. Movement was similar to yesterday but with less soaring flight.
