Thursday, November 15 Mount Lorette [Day 53] 0800-1900 (Cliff Hansen, assisted by Rick Robb). The temperature at 0800 was -1C, the high was 4C (1200-1400) and it was 3C at 1700. Ground winds were S 0-8 gusting to 25 km/h at 1600 and ridge winds were moderate SSW. Cloud cover was 100% stratus and cumulus at the start and then 70-90% stratus, cumulus and stratocumulus for the rest of the day. The east ridges were clear all day and the west was clear to 1200 when it was 10% obscured and gradually increased to 50% by 1700. The only migrant raptors seen were 2 Golden Eagles gliding above the Fisher Range ridge: an adult at 1038 and an unaged bird at 1528. The path to the site early in the morning revealed the tracks of 3 Grey Wolves, 1 Red Fox and 1 Coyote that led to the carcass of a freshly killed White-tailed Deer on a gravel bar in the river south of the Hay Meadow site. Perched in adjacent trees were 3 adult Bald Eagles and a juvenile Bald Eagle was perched on the gravel bar, while 2 more Bald Eagles (1a, 1sa) were perched in trees farther south along the river. Ten ravens and 2 magpies were also in attendance. By 1600 the carcass had been entirely consumed. Other birds seen were 1 Belted Kingfisher, 4 Canada Jays, 1 Pacific Wren, 15 Lapland Longspurs and 6 White-winged Crossbills. Seven visitors were at the site today. The spring 2019 count at Mount Lorette will start on March 1.

RMERF counts, November 14
Wednesday, November 14 Mount Lorette [Day 52] Hay Meadow 0815-1500, Lusk Creek 1615-1650 (Blake Weis, assisted by Heinz Unger). The temperature at 0815 was 2C, the high was 4C (1100-1300) and it was 1C when heavy snow ended observation at Hay Meadow, and when Blake resumed the count at Lusk Creek. Ground winds to 1100 were variable 0-10 gusting 15 km/h and then were W-SW 5-10 gusting 20 and occasionally 50 km/h. Ridge winds were moderate to strong W-NW to 1200 and then W-SW. Cloud cover was initially 50% altocumulus, altostratus, cumulus, cirrus and cirrostratus that increased to 100% from 1200 to 1300 when 100% stratocumulus developed that obscured all ridges and brought moderate snow that became heavy at 1500 when the Hay Meadow count ended for the day. A total of 11 migrant raptors of 3 species were counted between 0924 and 1212 comprising 3 Bald Eagles (2a and 1 undifferentiated immature), 1u Northern Goshawk and 7 Golden Eagles (4a, 3u). All the eagles moved at varying heights along the Fisher Range and maximum hourly counts were 4 between 1000 and 1100 and again between 1100 and 1200. Around 1600 the snow stopped and Blake went to the Lusk Creek site between 1615 and 1650 where the highest foothills ridge was clear and recorded a further 3 migrants: 1 adult Bald Eagle, 1u Northern Goshawk and 1u Golden Eagle. An adult resident Northern Goshawk soared near the Hay Meadow site at 1310, and other birds near the site were a pair of Mallards that flew low to the south above the river, 1u Northern Shrike, 4 Canada Jays, 1 Black-billed Magpie, 2 Clark’s Nutcrackers that flew low to the south, 6 Common Ravens, 3 Black-capped, 3 Mountain and 1 Boreal Chickadee, 12 Bohemian Waxwings, 520 Common Redpolls, most of which were south-bound migrants, 112 White-winged Crossbills, 11 Pine Siskins and 3u Dark-eyed Juncos. Six visitors arrived at the site before the snow started to fall. Tomorrow will be the last day of the fall 2018 count.

Wednesday, November 14 Vicki Ridge [Day 49] 0745-1645 (Peter Sherrington, assisted by Hilary Atkinson observing from the Waterton 61 wellsite, and Gord Petersen observing from the Waterton 68 wellsite, 1415-1600). The temperature at 0745 was 3C, the high was 5.5C at 1300 and it was 0C at 1645. Winds were strong W all day 40-50 gusting 60-70 km/h apart from 1400 and 1500 when they were WSW 60 gusting 80-90 km/h. Cloud cover was initially 20% altocumulus and cirrus to 0900 when it increased to 50% altostratus, altocumulus, cumulus and cirrus that reached 100% at 1100. Between 1200 and 1410 cloud cover was 60-80% cirrostratus, altostratus and altocumulus, but at 1410 stratus cloud quickly moved from the west that brought snow until 1630 when the sky quickly cleared to 30% cumulus. The ridges were partially obscured between 1410 and 1540 and then completely obscured to 1630. There was another fairly strong late-season raptor movement of 30 birds of 3 species between 0804 and 1525 that comprised 7 adult Bald Eagles, 1 light morph Rough-legged Hawk, 21 Golden Eagles (15a, 2sa, 1j, 3u) and 1 unidentified eagle. The total includes 4 Golden Eagles (2a, 2u) seen by Gord Petersen between 1429 and 1525 at the western edge of Kyllo Ridge near the Waterton 68 wellsite. The maximum hourly count was 8 between 1000 and 1100 and the last 8 birds moved through steady light snow before heavy snow at 1530 brought all movement to an end. Other birds were scarce apart from about 70 Common Ravens which were continuously in the air until the snow arrived, attracted to the area by gut-piles from recently hunted deer. Tomorrow will be the last day of the fall 2018 count.

RMERF counts, November 11
Sunday, November 11 Mount Lorette [Day 49] 0855-1700 (Blake Weis, assisted by Lori Anderson). The temperature at the start was -7C, the high was -2C (1400-1600) and it was -3C at 1700. Ground winds were 0-5 km/h all day, mainly WSW to 1300 and then N, and ridge winds were moderate NW all day. Cloud cover was 100-80% stratocumulus to 1200 that produced heavy to light snow, quickly cleared between 1200 and 1300 to 40% cumulus, altocumulus and cirrus before returning to 100% stratocumulus and moderate snow between 1300 and 1400; the rest of the day was 30% cumulus, altocumulus and cirrus. Both the eastern and western ridges were 100% obscured to 1200. The east was 40% obscured to 1300, 100% to 1400 and 30-0% thereafter, while the west was 90% obscured to 1300, 100% to 1400 and 20-0% thereafter. Despite the weather there was a fairly strong late-season count of 33 birds of 4 species between 1148 and 1550 that comprised 10 Bald Eagles (6a, 3sa, 1j), 1u Rough-legged Hawk, 21 Golden Eagles (16a, 3sa, 2u) and 1u columbarius Merlin. All the eagles moved in the face of the Fisher Range or at ridge level and there was much flapping and soaring flight. The maximum hourly count was 13 (2 Bald and 11 Golden Eagles) between 1400 and 1500. A non-migrant adult Bald Eagle perched by the river for 2 hours and an adult resident Golden Eagle traversed the Fisher Range from north to south before crossing the valley to Mount Lorette. Other birds identified were 1 male Hairy Woodpecker, 1 female American Three-toed Woodpecker, 1 Pileated Woodpecker, 5 Canada Jays, 7 Common Ravens, 1 Black-capped and 1 Mountain Chickadee, 1 Golden-crowned Kinglet, 50 Common Redpolls, 3 White-winged Crossbills, 2 Pine Siskins and 1u Dark-eyed Junco. A total of 18 visitors made it to the site after the snow stopped falling.

Sunday, November 11 Vicki Ridge [Day 46] 0945-1645 (Peter Sherrington, assisted by Hilary Atkinson and Gord Petersen observing from the Waterton 61 wellsite). Snow started to fall at dawn and quickly obscured the ridges but at 0930 it became light so we went to the site and found both Vicki Ridge and Kyllo Ridge essentially clear. The ridges remained visible but partially obscured until 1100 when heavier snow returned and the ridges again disappeared. At 1300 the snow abruptly stopped and within minutes both ridges were clear and by 1310 cloud cover was 40% cumulus and there was hazy sunshine. The temperature at 0945 was -4C, the high was -3C at 1400 and 1500 and it was -6C at 1645 under a completely cloudless sky. Winds were variable light to calm all day. The first migrant was an adult female columbarius Merlin that flew low and rapidly to the south on the western flank of Vicki Ridge at 1326 but the main movement of 25 of the day’s 27 migrants occurred between 1339 and 1524 and involved 19 Bald Eagles (10a, 2sa, 7j), 1 light morph Rough-legged Hawk and 5 adult Golden Eagles. Most of the birds soared high above the valley between the two ridges and drifted and glided slowly to the south and up to 7 birds were seen at one time. The only other migrant was an unidentified eagle that flew south at 1608 against the face of the setting sun. Four geese that flew high from NE to SW over Kyllo Ridge at 1611 were probably Greater White-fronted Geese, and other birds seen were 1 Canada Jay, 10 Common Ravens, 1 American Robin that flew high to the NW, 14 Bohemian Waxwings, 12 Grey-crowned Rosy-Finches and 4 Red Crossbills.

Sunday, November 11 Steeples [Day 47] 1200-1700 (Vance Mattson). The temperature was 1C, conditions were calm, cloud cover was 60-40% stratus and cumulus and once again the ridge was obscured although it was otherwise a sunny day. A total of 7 adult eagles, 1 Bald Eagle and 6 Golden Eagles, moved sporadically low to the south in front of the ridge and beneath the cloud between 1322 and 1548. Soaring birds at times disappeared into the base of the cloud before gliding south in front of the shrouded ridge.
