0 comments

Monday, March 16 Beaver Mines [Day 21] 0730-2000 (Peter Sherrington and Hilary Atkinson). The temperature at 0730 was -12C, the high from 1400 to 1800 was 1C and it was  -3C at 2000. Winds were W-NW 10-18 km/h to 1400 after which they were variable and light (0-8 km/h) for the rest of the day. There was 40% stratus cloud cover at 0700 after which it was cloudless all day. The light winds again produced a very poor raptor movement with only 3 birds, 1 subadult Bald Eagle and 2 adult Golden Eagles recorded between 1702 and 1705. The birds soared high above the ridge before flapping to the NW. At the Frank Slide Interpretive Centre in the Crowsnest Pass, however, Trevor Lewis saw 32 eagles moving to the north along the Livingstone Ridge in 16 minutes around 1600 with the birds probably originating from the Carbondale Ridge to the west of the Beaver Mines site. A strong eagle movement also occurred at Mount Lorette where Blake Weis saw a season high 177 birds that comprised 5 Bald Eagles and 172 Golden Eagles. Other birds seen here were 8 Rock Pigeons, 1 Eurasian Collared Dove, 3 Downy Woodpeckers, 1 Hairy Woodpecker, 1 Northern Shrike, that was the first at the site this season, 1 Steller’s Jay, 4 Black-billed Magpies, 49 Common Ravens, 8 Black-capped Chickadees, 12 Mountain Chickadees, 2 Red-breasted Nuthatches, 1 White-breasted Nuthatch, 10 European Starlings, 6 Evening Grosbeaks, 25 Pine Grosbeaks, 1 American Tree Sparrow and 22 Dark-eyed Juncos (1 hyemalis, 1 cismontanus and 25 montanus). On March 15 Connie Simmons saw the area’s first Varied Thrush along the Gladstone Valley Road.

Monday, March 16 Steeples [Day 12] 1530-1900 (Vance Mattson). The temperature was 4C and conditions were calm, cloudless and sunny which produced low gliding flight and offered excellent views of 21 migrants that comprised 2 Bald Eagles (1a, 1j), the season’s first migrant Red-tailed Hawk, an adult light morph of the race calurus that was the last bird seen at 1849, and a season-high 18 Golden Eagles (16a, 2j), the first of which was moving across the ridge as Vance arrived at the site. No resident birds were seen.

Monday, April 22 Mount Lorette [Day 51] 0700-1845 (Blake Weis, assisted by Eric Langshaw). The starting temperature was 3C, the high was 15C from 1600 to 1800 and it was 12C at the end of the count. Ground winds were SSW to 1500 0-5 gusting up to 35 km/h, and SE-SW 5-10 gusting to 48 km/h for the rest of the day; ridge winds were SW all day, moderate to strong to 1300 after which they were strong to very strong. Cloud cover was 20-30% cirrus to 0900 and then 50-100% variable mixtures of cirrus, cirrostratus, altocumulus, cirrocumulus, cumulus and lenticular cloud with stratocumulus developing from the west after 1800, that 30% obscured the western mountains and brought rain that ended the count at 1845. Otherwise, the ridges were clear all day. The last day of the count saw a migration of 8 raptors of 5 species between 1134 and 1815 that comprised 1 Osprey, that was the only bird seen on the western route, 2u Sharp-shinned Hawks, 1u Cooper’s Hawk, 1 adult light morph calurus Red-tailed Hawk, 2u Golden Eagles and one medium-sized unidentified distant raptor. Apart from the Osprey all birds moved above the Fisher Range ridge or above the eastern side of the valley at variable heights, and 4 of the birds were seen between 1300 and 1400. A resident adult Northern Goshawk displayed above Olympic Summit at 0920, an adult Red-tailed Hawk was seen hunting on three occasions over Hummingbird Plume Hill and a resident adult Golden Eagle hunted on the SW flank of Mount Lorette at 1235. Other birds recorded in the area were 3 Canada Geese, 1 pair of Mallards, 1 male Common Merganser, 4 drumming Ruffed Grouse, 1 Wilson’s Snipe, 1 male Belted Kingfisher (the first of the season), 1 pair of Downy Woodpeckers, 1 pair of Northern Flickers, 6 Common Ravens, 6 Black-capped Chickadees, 9 Mountain Chickadees, 2 Boreal Chickadees, 3 Red-breasted Nuthatches, a pair of American Dippers at Troll Falls, 5 Golden-crowned Kinglets, 4 Ruby-crowned Kinglets, 1 pair of Mountain Bluebirds, 18 American Robins, 26 European Starlings, 1 American Pipit, 3 Pine Siskins, 1 singing Fox Sparrow, 2 Savannah Sparrows that were the first of the season, 2 Song Sparrows, 2 female Red-winged Blackbirds and 2 male Yellow-rumped Warblers (1 “Audubon’s” and 1 of undetermined race) that were also new for the season.

Monday, April 22 Beaver Mines [Day 51] 0600-2100 (Peter Sherrington assisted by Hilary Atkinson). The temperature at 0600 was 7C, dropped to the day’s low of 6C at 1700 before rising to a high of 16 C at 1300 and 1400 and again at 1600, and it was still 11C at 2100. Winds were W-WSW 15-25 gusting 40 km/h to 0900 after which they were strong W-WSW all day, 40-60 gusting to 85 km/h. Cloud cover was 100% cirrostratus and cirrocumulus to 1200, reduced to 80% cirrocumulus, cirrus and cirrostratus at 1300 and was mainly 100% stratus, lenticular, altocumulus and cumulus form the rest of the day, giving excellent viewing conditions throughout. There was a surprisingly strong and varied raptor migration for the last day of the count with 79 birds of a site record 16 species moving between 0757 and 2034. The flight comprised a site-record 4 Turkey Vultures (2a, 2u), 1 Osprey, 5 Bald Eagles (3a, 2j), 6 Northern Harriers (3 males: 2a, 1j, 2 females: 1a, 1j, and 1u), 10 Sharp-shinned Hawks (1a, 9u), 2 Cooper’s Hawks (1a, 1u), 4 Northern Goshawks (2a, 2u), 3 light morph Broad-winged Hawks (1a, 2u), 1 juvenile light morph Swainson’s Hawk, 4 light morph calurus Red-tailed Hawks (2a, 2u), 1 dark morph Rough-legged Hawk, 32 Golden Eagles (6a, 7sa, 15j, 4u), 2 American Kestrels (1 male, 1u), 1u columbarius Merlin, 1 adult female Peregrine Falcon and 2 Prairie Falcons (1 male, and 1 female that was the last bird of the spring 2019 count at 2034).

It was cloudless to 1300 when 40-100% thin to moderate altostratus developed that gave excellent viewing conditions for the rest of the day. The ridges were completely clear. There was a strong raptor movement for so late in the season with a total of 56 birds of 6 species moving between 1053 and 2032 that comprised 4 Bald Eagles (2a, 1 late subadult and 1 undifferentiated immature bird), a season-high 4 Sharp-shinned Hawks (1j, 3u), 1u Cooper’s Hawk that was the first of the season, 3 Northern Goshawks (1a, 2u), 3 adult light morph calurus Red-tailed Hawks and 41 Golden Eagles (5a, 2sa, 11j, 23u).

Sunday, April 21 Steeples [Day 41] 1300-1730 (Vance Mattson). The temperature was 15C, conditions were calm and cloud cover of 10-20% cumulus and cirrus gave continuous sunshine. Only two migrants were seen: 1 juvenile Bald Eagle at 1528, and 1 juvenile Golden Eagle at 1423 that was the first migrant bird of the species seen at the site since April 6. Non-migrants were 20 Turkey Vultures that included a kettle of 7 birds, 1 adult Bald Eagle, 1u Northern Goshawk and 3 sightings of single Red-tailed Hawks.

Saturday, April 20 Mount Lorette [Day 49] 0705-2015 (Blake Weis, assisted by Ruth Morrow). The starting temperature was 0C, the high was 8C at 1700 and 1800 and it was 6C at the end of observation. Ground winds were SW 0-5 km/h to 1000, N-NW 0-5 gusting 20 km/h to 1900 and N-NW 0-10 km/h for the rest of the day, while ridge winds were moderate SW all day. Cloud cover was 100% low stratus and fog that obscured all ridges to 1000 when it began to break to 90% stratocumulus, cumulus, cirrus and stratus and further reduced to 70% at 1500,, and was then 70-80% cumulus, cirrus, altocumulus and cirrocumulus for the rest of the day. The eastern ridges did not fully clear until 1700 and the west not until 1800, but the only precipitation was light snow flurries between 1100 and 1200. Locating conditions were excellent after 1000 and resulted in the highest count since April 12 that comprised 33 migrants of 6 species seen between 1117 and 1952. The count was 2 Ospreys that were the first of the season. 3 Bald Eagles (1a, 2sa), a season-high 4 adult Northern Harriers (3 males, 1 female), 2 adult light morph calurus Red-tailed Hawks, 4 Rough-legged Hawks (3 light, 1 dark), 2 unidentified Buteos, 15 Golden Eagles (3a, 2sa, 9j, 1u) and 1 unidentified eagle. Birds moved fairly steadily throughout and peaked between 1800 and 1900 when 1 Osprey and 8 Golden Eagles were seen. Most birds were seen over the western part of the valley to 1400 after which they were mainly located above the Fisher Range although some eagles seen over Mount Lorette later in the day may have originated from Wasootch Creek north of the Fisher Range. Resident birds were 1 adult Bald Eagle that flew south from Mount Old Baldy at 1400, 3 sightings of single adult Northern Goshawks and 1 calling from the nest site, three sightings of single soaring Red-tailed Hawks and 1 adult Golden Eagle that soared high above the Fisher Range at 1555 before gliding high to the south. Other birds in the area were 4 Canada Geese, 5 Mallards, 3 drumming Ruffed Grouse, 1 Killdeer, 1 Wilson’s Snipe that performed its winnowing display flight for the first time this season early in the morning, 1 Hairy Woodpecker, 4 Northern Flickers, 12 Common Ravens, 3 Tree Swallows, 2 Black-capped Chickadees, 6 Mountain Chickadees, 2 Boreal Chickadees, 6 Red-breasted Nuthatches, 3 American Dippers 2 of which were seen at Troll Falls, 10 Golden-crowned Kinglets, 3 Ruby-crowned Kinglets, 2 male and 1 female Mountain Bluebirds, 6 singing Varied Thrushes, 39 American Robins including a single flock of 13, 2 American Pipits, 1 White winged Crossbill, 2 Red Crossbills, 7 Pine Siskins, 1 singing Fox Sparrow, 4 Song Sparrows, 16 Dark-eyed Juncos, 1 of which was hyemalis and 3 montanus, and 1 male Red-winged Blackbird. Three White-tailed Deer fed in the meadow late in the evening, 3 Bighorn Sheep were seen on Olympic Summit and there were fresh tracks of Canada Lynx and Black Bear in the 2cm of snow that had fallen overnight. There were 15 visitors to the site today.

Saturday, April 20 Beaver Mines [Day 49] 0630-2030 (Peter Sherrington assisted by Hilary Atkinson). The temperature at 0630 was 2C, the high was 7C at 1700 and it was 5C at 2030. Winds were calm or light (<5 km/h) to 1400, then NE 10 km/h and finally SW-W 10-15 km/h after 1900. Cloud cover was 100% stratus almost throughout the day that began to break at 2015 and reduced to 80% cumulus at 2030. Steady light and occasionally moderate rain started falling at 0840 and persisted to 1550 after which there were further periods of rain to 1820, and the ridge was obscured between 0930 and 1200. There was a compressed raptor movement of 12 birds of 7 species between 1503 and 1752 that comprised 3 Bald Eagles (1a, 2j), 2 adult Northern Harriers (1 female and 1 male), 1u Sharp-shinned Hawk, 2 adult light morph calurus Red-tailed Hawks, 1 light morph juvenile Ferruginous Hawk, 1 subadult Golden Eagle and 2 female columbarius Merlins (1a, 1u). Six of the birds were seen between 1503 and 1600 and 4 between 1711 and 1752. Resident birds were a pair of Northern Harriers and 2 pairs of Red-tailed Hawks that hunted low above the bottom of the valley, a non-migrant juvenile Northern Goshawk that made three low hunting passes at a group of Mallards on the creek, the third of which was presumably successful as it failed to re-appear from the willow shrub behind which it dived at 1943, and a male Prairie Falcon hunted songbirds in the rain near the site at 1215. Other birds were 1 Greater White-fronted Goose that flew to the NE above the valley at 1910, a pair of  Canada Geese, 2 pairs of Wood Ducks, 12 Mallards, 1 pair of Green-winged Teal, a pair of Common Mergansers that flew high to the north at 1732, 9 Rock Pigeons, a pair of Sandhill Cranes that fed by the creek at 1518, 2 pairs of Downy Woodpeckers, 1 pair of Hairy Woodpeckers, 1 pair of  Northern Flickers, 4 Blue Jays, 1 Clark’s Nutcracker, 5 American Crows, 11 Common Ravens, 14 Tree Swallows most of which flew high towards the SW, 2 Black-capped Chickadees, 2 Mountain Chickadees, 2 Red-breasted Nuthatches, 1 American Dipper that flew high to the NE above the creek at 2028, 1 Ruby-crowned Kinglet, 5 American Robins, 88 European Starlings, 32 Evening Grosbeaks, 2 female Cassin’s Finches, 10 Pine Siskins and 11 male Red-winged Blackbirds that included 5 females which were the first seen here this year.

Saturday, April 20 Steeples [Day 40] 1300-1800 (Vance Mattson). The temperature was 15C, winds were moderate N and cloud cover was 100% thin altostratus and cumulus that reduced to 40% cumulus and produced mainly sunny conditions. The 6 migrants seen comprised 5 Bald Eagles (3a, 2j) and 1u Sharp-shinned Hawk, with 3 of the Bald Eagles moving between 1545 and 1600. Non-migrants were 11 Turkey Vultures, 4 Bald Eagles (1a, 3j), 1 adult Northern Goshawk, three sightings of single Red-tailed Hawks including one that displayed, and 1 juvenile Golden Eagle that was intensely harried by a Red-tailed Hawk but remained entirely aloof throughout a series of bombing flights.

Friday, April 19 Mount Lorette [Day 48] 0715-1600 (Cliff Hansen, assisted by Rick Robb). The temperature at 0715 was 7C, the high was 9C between 1000 and 1200 and it was 4C when the count was abandoned for the day in the rain at 1600. Winds were light (<5 km/h) at the Hay Meadow site, where the 100% stratus cloud cover produced light rain and descended to substantially cover the ridges by 0900 when the observers decided to relocated to the Lusk Creek site. There winds were NW 5-10 gusting 25 km/h, cloud cover was 100% stratus and cumulus and the ridges were clear, but rain started at 1200 and by 1300 all ridges were obscured. One resident adult calurus Red-tailed Hawk was seen, but there were no migrants. Other birds at the Hay Meadow were 6 Canada Geese, a pair of Mallards, 1 drumming Ruffed Grouse, 1 Northern Flicker, 2 Common Ravens, 1 male Mountain Bluebird, 6 American Robins, 2 Black-capped Chickadees, 2 Mountain Chickadees, 1 Red-breasted Nuthatch and 1u Dark-eyed Junco. At Lusk Creek other birds were 1 Downy Woodpecker, 1 Pileated Woodpecker, 1 singing Townsend’s Solitaire, 1 American Robin and 6 singing Dark-eyed Juncos. One visitor stopped by the Lusk Creek site.

Friday, April 19 Beaver Mines [Day 48] 0630-2030 (Peter Sherrington assisted by Hilary Atkinson). The temperature at 0630 was 12C that rose to a season-high 19C at 1330 before quickly dropping down to 9C at 2030. Winds were strong W-WSW 45-55 gusting 80 km/h to 1700 after which they moderated to 20-30 gusting 40 km/h. Cloud cover was 0-20% cumulus to 1200 when it thickened to 60% altocumulus, altostratus, cirrus and cumulus and throughout the afternoon it was 90-100% altostratus, stratus and cumulus that brought light to moderate rain between 1500 and 1830 and then occasional showers for the rest of the day. There was a fairly varied raptor movement involving 20 birds of 7 species between 0932 and 1456 when rain stopped migration which did not restart despite seemingly ideal migration conditions after 1830. The count was 1 adult Turkey Vulture, 1 adult female Northern Harrier, 3 Sharp-shinned Hawks (1a, 2u), the first 2 light morph Broad-winged Hawks (1a, 1u) of the season that soared high above the centre of the valley with a Golden Eagle at 1248, 5 Red-tailed Hawks (2a and 2u calurus light, and 1 dark adult harlani), 7 Golden Eagles (3a, 2sa, 1j, 1u) and 1u columbarius Merlin. The resident Northern Harrier pair hunted throughout the day and up to 4 resident Red-tailed Hawks were seen hunting before the rain started. Other birds seen in the area were a pair of  Canada Geese and 8 that flew high to the SW in 2 flocks, 2 pairs of Wood Ducks, 3 pairs of  Mallards and 3 pairs of Green-winged Teal, 12 Rock Pigeons, 1 pair of Downy Woodpeckers, 1 pair of  Northern Flickers, 4 Blue Jays, 2 Black-billed Magpies, 6 American Crows, 8 Common Ravens, 1 pair of Tree Swallows, 8 American Robins, 5 European Starlings, 15 Evening Grosbeaks, 10 Pine Siskins and 4 male Red-winged Blackbirds.

Thursday, April 18 Mount Lorette [Day 47] 0715-2010 (Blake Weis, assisted by Rachel MacKay). The temperature at 0715 was 5C, the high was 14C from 1700 to 1900 and it was 12C at 2010. Ground winds were W-SW all day, 2-5 gusting 15 km/h to 0900 and then 5-10 gusting to 32 km/h for the rest of the day, while ridge winds were moderate to strong NW all day. Cloud cover was initially 40% altocumulus, lenticular cirrus and altostratus that gradually spread to 70% at 1100; between 1100 and 1300 it was 80-90% cumulus, altocumulus, altostratus, cirrus, cirrocumulus and cirrostratus, at 1300 and 1400 it was 100% altostratus and cumulus and for the rest of the day it was variable 50-80% cumulus, altocumulus, altostratus and cirrus with minor stratocumulus developed to the west. The variety of cloud forms was not matched by the number of raptor migrants as again only two were seen: 1 adult light morph calurus Red-tailed Hawk that flew north from the Fisher Range at 1458 and an immature Bald Eagle that flew from the south face of Mount Lorette to Mount McGillivray and on to the NW at 1844. Resident birds were a pair of Red-tailed Hawks soaring over Hummingbird Plume Hill and single birds, probably of the same pair, that hunted north of the site, and an adult Golden Eagle that flew low from Mount Lorette to the Fisher Range at 1140. Other birds noted in the area were 3 Canada Geese and a pair of Mallards on the river, 3 drumming Ruffed Grouse, 1 Hairy Woodpecker, 3 Northern Flickers, 1 Canada Jay, 1 American Crow, 7 Common Ravens, 3 Black-capped Chickadees, 2 Mountain Chickadees, 2 Boreal Chickadees, 2 Red-breasted Nuthatches, 1 American Dipper seen at Troll Falls, 1 Golden-crowned Kinglet, 1 singing Ruby-crowned Kinglet, 1 male and 2 female Mountain Bluebirds, 2 singing Varied Thrushes, 15 American Robins, 2 American Pipits, 12 White winged Crossbill, 2 Pine Siskins, 1 Fox Sparrow that sang only in the morning, 1 singing Song Sparrow, 10 Dark-eyed Juncos, 3 of which were montanus, the first Western Meadowlark of the season and 1 male Red-winged Blackbird. Three White-tailed Deer fed in the meadow early in the morning and again late in the evening, a single Bighorn Sheep was seen on Olympic Summit, and there were 5 visitors to the site today.

[Addenda to April 17 report: while driving to the site, at 0945 Cliff saw an adult light morph Ferruginous Hawk soaring low at the confluence of the Kananaskis and Bow Rivers, 18 km NNE of the Hay Meadow site. Three Mountain Bluebirds, 2 males and 1 female, were also seen in the Hay Meadow.]

 

Thursday, April 18 Beaver Mines [Day 47] 0630-2045 (Peter Sherrington assisted by Hilary Atkinson). The temperature at 0630 was already 7C, the high at 1200 and again at 1600 was 14C and it was still 10.5C at 2045.

Cloud cover was 60-100% altostratus, cumulus, cirrus, cirrocumulus, altocumulus and lenticular to 1530, 20-70% cumulus to 1900 and then 100-30% thin cirrostratus and cumulus for the rest of the day. Observing conditions were very good all day and produced a varied if sporadic movement of 22 raptors of 11 species between 0926 and 1821. The flight was 1u Turkey Vulture at 1703, 1 Osprey at 1640, both of which were the first of the season, 1 subadult Bald Eagle, 3u Sharp-shinned Hawks, 2 Cooper’s Hawks (1a, 1u), 2 Northern Goshawks (1j, 1u), 1 adult light morph Ferruginous Hawk, 1 dark morph Rough-legged Hawk, 7 Golden Eagles (3a, 4j), 2 columbarius Merlins (1 male, 1 female) and 1 male Prairie Falcon. Resident birds were 1 male Northern Harrier and sporadic sightings of hunting Red-tailed Hawks. Other birds seen were 1 Canada Goose, 2 male and 1 female Wood Ducks, 5 Mallards and 2 pairs of Green-winged Teal on the creek, a lek of 8 Wild Turkeys that comprised 5 very aggressive displaying males that fought amongst themselves and 3 females that completely ignored them and calmly fed close by, 17 Rock Pigeons, single Sandhill Cranes that flew high to the SW at 0913 and 1801, 1 Wilson’s Snipe, 1 Downy Woodpecker, 2 male Northern Flickers, 6 Blue Jays, 2 Black-billed Magpies, 4 American Crows, 32 Common Ravens, 1 Tree Swallow, 4 American Robins, 65 European Starlings, 30 Evening Grosbeaks, 1 female Cassin’s Finch, 15 Pine Siskins and 7 male Red-winged Blackbirds.

Thursday, April 18 Steeples [Day 39] 1300-1730 (Vance Mattson). The temperature was 14C, winds were moderate to strong S and cloud cover was 100% altostratus and cumulus that slightly obscured the ridges at 1700 and brought light rain. It was another slow day with no migrant raptors and just one non-migrant juvenile Bald Eagle seen.
