Friday, April 5 Mount Lorette [Day 34] 0740-2040 (Caroline Lambert, assisted by Patrick Farley). The temperature reached a high of 11C from a morning low of -1C and was 5C at 2040 when observation ceased. Ground winds were light all day, variable to 1100,  NE to 1400, SE to 1700 and SW after 1800, while ridge winds were SW all day, light to 1500 after which they were moderate. Cloud cover was 100% stratus, altocumulus and altostratus which broke up to 70-80% after 1500. Conditions were hazy with light mist to 1500, and the western mountains were 20-80% obscured after 1000; apart from Mount Lorette being briefly obscured around noon the eastern route was clear all day. There was a fairly strong raptor movement of 57 birds of 3 species between 1038 and 1942 that comprised the season’s first Turkey Vulture, of unknown age, that flew to the  north above the eastern valley at 1325, 2 adult Bald Eagles, 53 Golden Eagles (21a, 6sa, 2j, 24u) and 1 unidentified eagle. Only 5 birds were seen before 1400 but movement was then steady and peaked at 15 Golden Eagles between 1800 and 1900. All birds moved on the eastern route to 1345 when they switched to the west where birds again soared high on Olympic Summit before gliding high to the NW behind the summit of Mount Allan; between 1510 and 1660 both routes were used and after 1600 all birds glided high from the Fisher Range to Mount Lorette. Resident birds were 1 adult Sharp-shinned Hawk seen hunting north of the site, 1 adult Northern Goshawk, 1u Bald Eagle and the resident pair of Golden Eagles that spent much of the day around Olympic Summit where the male displayed several times. Other birds seen were 10 Canada Geese, 1 Downy Woodpecker, 2 Hairy Woodpeckers, 2 Northern Flickers, 12 Common Ravens, 1 Black-capped Chickadee, 4 Mountain Chickadees, 4 Boreal Chickadees, 1 American Dipper, 2 Golden-crowned Kinglets that were with the season’s first Ruby-crowned Kinglet, 1 male Mountain Bluebird, 3 singing Varied Thrushes, 14 American Robins, 4 European Starlings, 10 White-winged Crossbills, 2 Pine Siskins, 7 Dark-eyed Juncos and 1 Song Sparrow. Twelve Bighorn Sheep were on Olympic Summit, 4 White-tailed Deer in the meadow and 5 visitors were at the site today.

Friday, April 5 Beaver Mines [Day 34] 0700-2015 (Peter Sherrington, assisted by Mark Sherrington and Hilary Atkinson). At 0700 the temperature was 0C the high at 1500 was 10.5C and it was 8C at 2015. Winds were light all day, variable but principally SE-ESE and although there was a gentle W upper flow all day it never lowered to ridge level. It was a generally dull day with 100% mainly stratocumulus cloud cover that brought very light rain and light snow to 1100 and again after 1445. The cloud began to break at 1700 and after 1730 it was 40-60% cumulus that gave sunny conditions. The conditions provided a very sporadic movement of 16 raptors of 6 species between 1111 and 1901 that comprised 1 adult Bald Eagle, 1 adult male Northern Harrier, 2u Sharp-shinned Hawks, a season-high 9 adult Red-tailed Hawks (6 light and 2 dark calurus and 1 dark harlani), 1 light morph Rough-legged Hawk and only 2 adult Golden Eagles. Five of the birds moved between 1800 and 1900. A resident adult Northern Goshawk made a display flight above the ridge at 1236, and the resident pair of Red-tailed Hawks soared and occasionally displayed between 1147 and 1834. Other birds in the area were 3 Canada Geese, 1 Mallard, 2 Rock Pigeons, 1 Sandhill Crane that soared high and called above the ridge at 1331 before flying high to the SE, 3 Downy Woodpeckers, 2 Hairy Woodpeckers, 2 Northern Flickers, 8 Blue Jays, 3 Black-billed Magpies, 14 American Crows, 16 Common Ravens, 2 Black-capped Chickadees, 2 Mountain Chickadees, 1 Red-breasted Nuthatch, 9 American Robins, 16 European Starlings, 40 Evening Grosbeaks, 20 Pine Siskins and 2 Dark-eyed Juncos (1 cismontanus and 1 montanus).

Friday, April 5 Steeples (Vance Mattson). NO OBSERVATION (weather). It was overcast all day with intermittent light drizzle. The mountains were shrouded all day except around 1700 when there was some clearing but they soon clouded over again.

Thursday, April 4 Mount Lorette [Day 33] 0640-2020 (Cliff Hansen, assisted by Rick Robb). The starting temperature was 3C, the high was 11C at 1700 and it was 7C at the end of observation. Ground winds were variable but mainly S 5-10 gusting 20 km/h to 1600, SW5-15 gusting 20 km/h to 1900 and then N 5-10 gusting 20 km/h for the rest of the day; ridge winds were mostly WNW moderate to strong to 1800 and then moderate NW. Cloud cover was variable 20-90% cumulus and altocumulus all day that gave good observing conditions and the ridges were clear, but despite this the raptor count was a disappointing 9 birds, made more so as it followed a week of strong movement. The first bird seen was a light morph Rough-legged Hawk at 1345, but eagle movement did not begin until after 1600 and comprised 1 adult Bald Eagle and 6 Golden Eagles (3a, 1sa, 1j, 1u) that moved up to 1943, with 4 of the Golden Eagles seen between 1800 and 1900; a mid-sized unidentified raptor was also seen during this hour. All the eagles glided high above the Fisher Range to Mount Lorette. A resident Northern Goshawk called from the nest site early in the morning and there was a single sighting of an adult resident Golden Eagle. Other birds recorded in the area were 2 Canada Geese, 10 unidentified gulls that soared over the northern end of the Fisher Range in the late afternoon before flying to the east, 1 Hairy Woodpecker, 2 Northern Flickers, 11 Common Ravens, 2 Black-capped Chickadees, 1 Boreal Chickadee, 1 Red-breasted Nuthatch, 1 singing Varied Thrush, 6 American Robins, 2 Bohemian Waxwings and 3 Dark-eyed Juncos. Twelve visitors were at the site today.

Thursday, April 4 Beaver Mines [Day 33] 0715-1945 (Peter Sherrington, assisted by Hilary Atkinson). At 0715 the temperature was 5.5C, the high was 11C at 1200 and 1300, and again at 1600 and 1700 and it was still 8C at 2015. Winds were W-WSW all day 25-40 gusting up to 60 km/h and cloud cover was variably 30-70% mainly cumulus to 1830 when 100-70% thin cirrostratus developed. Observing conditions were very good throughout and it was encouraging to see the first Golden Eagle gliding high to the north at 0759, but the second bird, an adult Bald Eagle, did not occur until 1103 and the second Golden Eagle was only seen at 1349. After this, however, the pace quickened and peaked at 21 birds between 1700 and 1800, with the last 3 Bald Eagles moving NNW at 1902. The final count of 57 raptors of 8 species was 14 Bald Eagles (11a, 2sa, 1j), 1 adult male Northern Harrier, 4 Sharp-shinned Hawks (1a, 3u), 1u Northern Goshawk, 8 adult calurus Red-tailed Hawks (5 light, 3 dark), 1 unidentified dark Buteo, 26 Golden Eagles (23a, 3j), 1 dark morph Gyrfalcon and 1 Prairie Falcon. Other birds seen were 1 Canada Goose, 25 Wild Turkeys, 18 Rock Pigeons, 2 Downy Woodpeckers, 1 Northern Flicker, 5 Blue Jays, 1 Black-billed Magpie, 30 American Crows, 18 Common Ravens, 4 Black-capped Chickadees, 4 Mountain Chickadees, 1 Red-breasted Nuthatch, 12 American Robins, 516 European Starlings, 35 Evening Grosbeaks 8 Grey-crowned Rosy-Finches that flew north at 1318, 14 Pine Siskins and 3 Dark-eyed Juncos (1 hyemalis, 1 cismontanus and 1 montanus).

Thursday, April 4 Steeples [Day 30] 1300-1900 (Vance Mattson). The temperature was 11C, winds were moderate to strong S-SE and 60-90% altostratus cloud cover gave partially sunny conditions. Only three migrants were seen: an adult Golden Eagle at 1452, a juvenile Golden Eagle at 1746 and a juvenile Bald Eagle at 1817. Non-migrants consisted of 10 sightings of Turkey Vultures, 3 sightings of adult Bald Eagles, 5 sightings of single adult calurus Red-tailed Hawks including 2 hovering hunting flights over the ridges, and 3 adult Golden Eagles that were seen twice including two birds that soared together while one displayed although there was no perceived antagonism between them.

Wednesday, April 3 Mount Lorette [Day 32] 0640-2020 (Bill Wilson, assisted by Glenn Webber and Graeme Dunlop). The temperature at 0730 was -5C, the high from 1400 to 1700 was 8C and it was 6C at the end of observation. Ground winds were variable 0-2 km/h to 1100 then S-SW for the rest of the day, 2-10 gusting to 27 km/h to 1700 and 2-10 km/h to 2015; ridge winds were moderate SW all day. Cloud cover was 100% altostratus throughout the morning and 100% cumulus and altostratus throughout the afternoon that provided hazy sunshine and good locating conditions but made detailed determination of age difficult. There was yet another strong April raptor migration with 113 birds of 3 species seen between 0914 and 1947. The flight was 12 Bald Eagles (9a, 1sa, 2j), 1u Sharp-shinned Hawk and 100 Golden Eagles (50a, 1sa, 9j, 40u). The Golden Eagle count of 510 for the first three days of April has already exceeded the long-term April average count for the species of 442. Once again birds moved steadily throughout with a highest hourly count of 23, including 18 Golden Eagles, between 1400 and 1500. Birds moved on both ridge systems to 1500 with the western birds again soaring high over Olympic Summit and gliding high to the NW behind the summit of Mount Allan, but after 1500 all birds flew on the eastern ridges gliding high from the Fisher range to Mount Lorette. There were several records of resident birds with a Northern Goshawk heard calling from the nest site early in the morning, 5 sightings of 1 or 2 adult Bald Eagles mainly moving southwards, and 3 of adult Golden Eagles including one that displayed against the face of Mount Bogart at 1221. Other birds recorded in the area were 75 Canada Geese that flew to the north in 6 flocks, 1 Ruffed Grouse, 1 Killdeer, 1 Northern Flicker, 1 Pileated Woodpecker, 15 Common Ravens, 1 unidentified flying swallow, 4 Mountain Bluebirds (1 male, 3u), 3 singing Varied Thrushes, 15 American Robins, 3 European Starlings, 30 Bohemian Waxwings in one flock, 1 singing White-winged Crossbill and 1 singing Dark-eyed Junco. There were 8 visitors at the site today.

Wednesday, April 3 Beaver Mines [Day 31] 0715-1945 (Peter Sherrington, assisted by Hilary Atkinson). The temperature was initially 0C, the high at 1300 was 10.5C and it was 6.5C at 1945. Winds were WSW-W all day, 10-20 gusting 25 km/h to 1135 after which they strengthened to 25-40 gusting to 65 km/h for the rest of the day. Cloud cover was mainly 100% altocumulus in the morning and 70-90% altostratus, altocumulus, cumulus and cirrus for the rest of the day, all of which provided good viewing conditions. Despite the favourable winds there was yet another desultory raptor movement with 16 birds of 6 species moving sporadically between 1108 and 1855. The flight comprised 4 adult Bald Eagles, the season’s first Cooper’s Hawk (an unaged bird), 1 adult Northern Goshawk, 5 light morph calurus Red-tailed Hawks (3a, 2u), the first Ferruginous Hawk of the season, an unaged light morph bird at 1714 and only 3 Golden Eagles (2a, 1sa). A resident pair of Red-tailed Hawks was present with birds seen displaying on a couple of occasions. A rather dull day was greatly enlivened towards the end when the first Sandhill Crane of the season soared high above the ridge at 1803 and flew high to the north and at 1814 a large flock of about 250 Snow Geese in several skeins flew to the east above the ridge: for a couple of minutes the sky was more reminiscent of Saskatchewan than SW Alberta! A more distant flock of 60 geese at 1757 were also probably Snow Geese. These numbers are unprecedented for the area. Other birds seen were 5 Canada Geese, a small flock of 14 Wild Turkeys that included 6 displaying males, 18 Rock Pigeons, 2 Downy Woodpeckers, 1 Hairy Woodpecker, a pair of Northern Flickers, 7 Blue Jays, 1 Black-billed Magpie, 56 American Crows, 19 Common Ravens, 2 Black-capped Chickadees, 1 Red-breasted Nuthatch, 1 Townsend’s Solitaire, 5 American Robins, 30 European Starlings, 27 Evening Grosbeaks and 8 Pine Siskins.

Tuesday, April 2 Mount Lorette [Day 31] 0730-2015 (Cliff Hansen, assisted by Rick Robb and Graham Dunlop). The temperature was -4C at 0730, the high at 1700 was 10C and it was 4C at 2015. Ground winds were very light 0-5 km/h to 1300 then S-SW 0-15 km/h to 1700 after which they were again very light, while ridge winds were light to moderate SW all day. It was initially cloudless with a trace of cumulus that gradually increased to a maximum of 40% at 1600 after which it gradually dwindled to a trace of cirrus at the end of observation. There was another strong raptor migration with 173 birds of a season-high 7 species moving between 1015 and 1931 that comprised 16 Bald Eagles (15a, 1sa), 2u Sharp-shinned Hawks, 1u Northern Goshawk, 1 Red-tailed Hawk of unknown age, morph or race, 2u Rough-legged Hawks, 1 unidentified Buteo, 147 Golden Eagles (51a, 3sa, 11j, 82u), 2 unidentified eagles and 1u columbarius Merlin. The lack of detail on many of the birds resulted from back-lighting of very high flying birds against an often clear blue sky. Movement was strong throughout the migration period with 93 birds seen before 1300 that included a maximum hourly count of 49 between 1200 and 1300, and the last 22 moved after 1800. All birds were seen on the western route until 1400 with birds again soaring very high on the southern flank of Mount Allan and Olympic Summit before gliding very high to the NW behind the summit of Mount Allan. After 1400 most birds used the eastern route with birds again soaring very high above the Fisher Range and gliding very high to the NW to Mount Lorette. A resident adult Northern Goshawk was seen on a nest, and the Golden Eagle pair was seen over Olympic Summit where the male displayed. Other birds recorded were 3 Canada Geese on the river, 1 female Common Merganser, 1 drumming Ruffed Grouse, the season’s first Killdeer, 1 Northern Flicker, 1 Pileated Woodpecker, 1 American Crow, 13 Common Ravens, 1 Red-breasted Nuthatch, 2 male Mountain Bluebirds in the meadow, 2 singing Varied Thrushes, 5 American Robins, 10 Bohemian Waxwings, a flock of 30 Grey-crowned Rosy-Finches that flew high on the Fisher Range and 2 Dark-eyed Juncos. A single Mule Deer unusually joined 11 White-tailed Deer to feed in the meadow, where a Striped Skunk was also seen. Five visitors were at the site today.

Tuesday, April 2 Beaver Mines [Day 31] 0730-2015 (Peter Sherrington, assisted by Hilary Atkinson). The temperature at 0730 was 0C, the high at 1400 and again at 1600 was 8C and it was 4C at 2015. Winds were very variable but principally from the NE to the SSE, mainly light but occasionally briefly gusting to 20 km/h. Cloud cover was 100-90% stratocumulus to 1030 that produced light snow flurries to 0830, 20-60% cumulus to 1500, 50-60% cumulus and altostratus to 1600 and finally 40% very thin cirrostratus with traces of altocumulus to 2015. Observation conditions were excellent and thermal lift was strong but the day only produced 9 migrant raptors comprising 5 adult calurus Red-tailed Hawks (4 light and 1 dark) and 4 Golden Eagles (3a, 1j). For much of the day a pair of resident light morph Red-tailed Hawks was present and conspicuous between 1124 and 1815 performing several low and high intensity display flights, soaring as a pair with legs dangling and hunting the valley floor. Other birds recorded were 6 Canada Geese,  6 Mallards, a pair of Common Mergansers that flew north at 1955, 1 calling Wild Turkey, 5 Rock Pigeons, 4 Downy Woodpeckers, 2 Hairy Woodpeckers, 1 Northern Flicker, 6 Blue Jays, 2 Black-billed Magpies, 40 American Crows, 10 Common Ravens, 4 Black-capped Chickadees, 4 Mountain Chickadees, 2 Red-breasted Nuthatches, 14 American Robins, 221 European Starlings, 32 Evening Grosbeaks, 1 female Cassin’s Finch, 8 Pine Siskins and 2 Dark-eyed Juncos (1 hyemalis and 1 montanus. Moderate SW winds are forecast so we are expecting a stronger raptor movement tomorrow.

Tuesday, April 2 Steeples [Day 28] 1230-1945 (Vance Mattson). The temperature was 9-11C, it was calm with intermittent light SE winds and mostly 50% cumulus which provided sunny conditions and a helpful backdrop for detecting high-flying birds throughout most of the day. A total of 33 migrant raptors of 4 species were seen between 1300 and 1908 comprising 13 Bald Eagles (11a, 2j), 3 adult Red-tailed Hawks (1 light calurus and 2 dark harlani), 1 light morph Rough-legged Hawk and 16 Golden Eagles (14a, 2j). Nine migrants moved between 1300 and 1400, but only 6 were seen in the next three hours (1400-1700); 12 (including 9 Golden Eagles) moved between 1700 and 1800, 4 between 1800 and 1900 and 2 between 1900 and 1908, the last being a “Harlan’s Hawk”. Movement was very high and fast, especially after 1700 when birds appeared high above the western peak of Mount Bill Nye. There was also much non-migrant activity with 14 sightings of Turkey Vultures, none of which exhibited migratory behaviour although at least one bird was in the air all day, 9 Bald Eagles (4a, 5j). 1u Northern Goshawk, 1 Red-tailed Hawk, and 4 Golden Eagles (3a, 1j) which performed a pair-flight low across the ridge and 2 display flights.

Monday, April 1 Mount Lorette [Day 30] 0700-1950 (George Halmazna, assisted by Dan Parliament and Graham Dunlop). The temperature was -3C at 0700, the high was 4C at 1600 and 1700 and it was 2C at the end of observation. It was calm to 1100, then ground winds were NE 2-8 km/h to 1400, SW2-5 km/h at 1500 and 1600 and NE 5-20 km/h after 1700; ridge winds were probably light to moderate W-NW. Cloud cover was 100-70% altostratus, altocumulus, cumulus and stratus all day with the exceptions of 1100 and 1900 when it reduced to 50%, and there were frequent snow flurries that swept from the west between 1300 and 1800. The eastern ridges were 90% obscured to 1200, 50% to 1400, 30% at 1500, clear at 1600 and 1700 and then 80-90% obscured after 1800; the west was 30% obscured to 0900 and then variably obscured to 1600 after which it was mainly clear. Remarkably these unpromising conditions produced a season-high total of 283 migrant raptors of 6 species between 1050 and 1845 that comprised 15 Bald Eagles (10a, 3sa, 2j), the season’s first Northern Harrier, a juvenile bird of unknown sex, 2 adult Northern Goshawks, 1 adult light morph calurus Red-tailed Hawk, a season-high 263 Golden Eagles (174a, 4sa, 10j, 75u) and 1u columbarius Merlin. Movement was mainly on the western route to 1500 with birds soaring high with kettles of up to 20 eagles that often disappeared into the cloud base, and then glided high to the NW either behind the summit of Mount Allan or above Skogan Pass. After 1500 the movement was entirely on the eastern route which saw the highest single hour count of 78 birds (76 Golden Eagles) between 1500 and 1600. Resident birds were 1 adult Bald Eagle, 1 calling and displaying adult Northern Goshawk, and the pair of resident Golden Eagles to the west where the male displayed above the southern flank of Mount Allan. Other birds recorded on a busy day were 4 Canada Geese, 1 drumming Ruffed Grouse, 1 Northern Flicker, 1 Pileated Woodpecker, 9 American Crows, 19 Common Ravens, 2 Black-capped Chickadees, 2 Red-breasted Nuthatches, 1 male Mountain Bluebird, 5 singing Varied Thrushes, 19 American Robins, 7 European Starlings, 10 Bohemian Waxwings and 8 Dark-eyed [Oregon] Juncos.

The temperature at 0730 was 0C, the high was 7C at 1600 and 1700 and it was 4C at 1930. Winds were light W-SSW to 1030, light NE –E to 1330 when they were mainly SW-SSW 5-10 gusting 15 km/h to 1900, after which it was calm. Heavy snow fell at 0730 that left 4 cm of fresh snow on the ground when it stopped at 0830 and the ridge cleared. Cloud cover was 100-70% stratocumulus, cumulus and altostratus in the morning that cleared throughout the afternoon giving excellent observing conditions to 1700 after which it was essentially cloudless. The day saw a season-high migration of 95 raptors of 6 species that moved between 1052 and 1841 and comprised 13 Bald Eagles (8a, 3sa, 2j), 1 adult male Northern Harrier, a season-high 7 adult Red-tailed Hawks (6 light and 1 dark calurus, and 1 dark harlani), a season-high 71 Golden Eagles (51a, 8sa, 10j, 2u), 1 unidentified eagle and 1 Prairie Falcon. The highest hourly count was 1400-1500 when 44 raptors were counted that included 35 Golden Eagles, 11 of which soared high together at 1440. A resident Golden Eagle displayed vigorously above the centre of the valley at 1429. Other birds in the area were 2 Canada Geese, 2 Tundra Swans that flew north at 1120 a distant flock of unidentified swans that flew north at 1444, 3 Mallards, 11 Wild Turkeys, 12 Rock Pigeons, a flock of 15 California Gulls, the first of the season, that flew north at 1205, 3 Downy Woodpeckers, 1 Hairy Woodpecker, 1 Northern Flicker, 1 Pileated Woodpecker, 1 adult Northern Shrike, 7 Blue Jays, 1 Black-billed Magpie, 37 American Crows, 23 Common Ravens, 2 Black-capped Chickadees, 3 Mountain Chickadees, 1 Red-breasted Nuthatches, a pair of Mountain Bluebirds, 17 American Robins, 70 European Starlings, 20 Evening Grosbeaks1 male Cassin’s Finch and 20 Pine Siskins.

Monday, April 1 Steeples [Day 27] 1630-1945 (Vance Mattson). Afternoon teaching commitments again resulted in a late start, but despite not arriving at the site at 1630 Vance counted 13 migrants: 3 adult Bald Eagles, 1 adult light morph calurus Red-tailed Hawk and 9 Golden Eagles (8a, 1u) between 1648 and 1919, the last of which was the latest bird seen this season. Most of the Golden Eagles moved in pairs. Non-migrants were 9 Turkey Vultures and the season’s first American Kestrel that mobbed a Golden Eagle as it flew low above the flank of Mount Bill Nye. The temperature was 11C, it was calm and 30-50% cumulus and altocumulus cloud cover gave sunny conditions.

Sunday, March 31 Mount Lorette [Day 29] 0710-2030 (Bill Wilson, assisted by Lori Anderson, Doug Pederson, Heinz Unger and Graham Dunlop). The starting temperature was -1C, the high was 7C at 1400 and 1500 and it was 1C at the end of observation. Ground winds were SSE-SSW 2-10 gusting 24 km/h to 1400, NNE 5-20 gusting 35 km/h to 1700 and then NNE-NNW 5-15 km/h for the rest of the day; ridge winds were probably moderate SW all day. Cloud cover was 100% stratus to 0900, 90-100% altostratus to 1200 and then 100% stratus for the rest of the day that gave light to moderate flurries between 1500 and 1700 and then light to moderate snow for the rest of the day. Ridges were mostly clear to 1300 becoming 20-30% obscured at 1400 and completely obscured after 1500. Despite the weather conditions there was a fairly strong raptor movement of 133 birds of 4 species between 0848 and 1736 that comprised 8 Bald Eagles (7a, 1j), 1 light morph Rough-legged Hawk, 121 Golden Eagles (70a, 2sa, 2j, 47u), 2 unidentified eagles and 1 large unidentified falcon. One hundred and one birds moved between 1100 and 1500 with a high hourly count of 38 between 1300 and 1400 and 2 Bald Eagles and 2 Golden Eagles moved in the falling snow between 1700 and 1736. Birds used both the western and eastern routes throughout the day with the majority (88 birds) using the west where they mainly soared over the southern flank of Mount Allan and Olympic Summit before gliding high to the NW behind the summit of Mount Allan. Resident birds were 2 adult Bald Eagles that soared at Mount Lorette and flew south at 1527, 2 records of Northern Goshawks, a resident adult light morph calurus Red-tailed Hawk that soared over the valley at 1147 and glided to the south, and 2 sightings of adult Golden Eagles including one that displayed over Mount Old Baldy at 1339. Other birds recorded were 4 Snow Geese that flew low, appropriately in the snow, above the river with Canada Geese where they landed at 1913, a further 120 Canada Geese that flew north in flocks of 50, 40 and 30, 1 Mallard, 1 female Common Merganser, 1 or 2 Ruffed Grouse, 9 (1+8) unidentified gulls that flew high to the north at 1511 and 1734 respectively, 2 Northern Flickers, 1 adult Northern Shrike, 2 Canada Jays, 17 Common Ravens, 2 Black-capped Chickadees, 1 Mountain Chickadee, 1 Red-breasted Nuthatch, 4 male Mountain Bluebirds in the meadow, 3 singing Varied Thrushes, 42 American Robins, 2 European Starlings, 160 Bohemian Waxwings in two flocks of 80 birds, 4 Red Crossbills, 1 Song Sparrow singing east of the river and 3 Dark-eyed Juncos.

Sunday, March 31 Beaver Mines [Day 29] 0730-2000 (Peter Sherrington, assisted by Hilary Atkinson). The temperature at 0730 was -1C the high at 1600 was 11C and it was 4C at the end of observation at 2000. Winds were variable and light to 1400 when they became mainly WSW 10-15 gusting 30 km/h to 1900, after which they were NE 10-15 km/h for the rest of the day. Cloud cover was mainly 100% stratocumulus to 1430 when it became 40-60% cumulus and cirrus to 1800 after which it was again 100% stratus and stratocumulus that produced light rain showers between 1900 and 1920. The day saw a moderate raptor movement of 70 birds (the second highest count of the season) of 6 species between 1121 and 1752. The flight was 9 Bald Eagles (6a, 3sa), 1 adult Northern Goshawk, 2 adult light morph calurus Red-tailed Hawks, 1 light morph Rough-legged Hawk, 55 Golden Eagles (31a, 4sa, 5j, 15u) and 1 male Prairie Falcon. Sixty-six birds moved between 1424 and 1752 coincident with the development of the moderate WSW winds, and the highest hourly count was 23 between 1600 and 1700. Other birds seen were 34 Canada Geese including a flock of 30 that flew high to the north at 0938, a leck of 36 Wild Turkeys including 2 displaying males, 9 Rock Pigeons, 3 Downy Woodpeckers, 5 Blue Jays, 20 American Crows, 12 Common Ravens, 4 Mountain Chickadees, 8 American Robins, 23 European Starlings, 40 Evening Grosbeaks, and 2 Pine Siskins.

Sunday, March 31 Steeples [Day 26] 1230-1930 (Vance Mattson). The temperature was initially 8C that rose to a high of 10C, conditions were calm throughout and cloud cover was 100% altostratus and dark cumulus that brought rain and obscured the ridges from 1430 to 1530, but was then 40% cumulus and thin altostratus that gave sunny conditions. Despite the weather interruption the day produced 35 migrant raptors of 4 species between 1253 and 1757 comprising 3a Turkey Vultures, the first migrants of the season, 14 Bald Eagles ((8a, 2sa, 4j), 1u Sharp-shinned Hawk that was the first bird seen and a first record for the season, and 17 Golden Eagles (13a, 2j, 2u). Migration was initially slow with just 4 birds seen before 1530, but 14 migrants were seen between 1533 and 1600 with many of the birds moving in light rain between the ridge and the site as the ridge was clearing. The ridges were clear by 1600 but only 1 migrant moved before 1700, but the following hour produced 16 migrants with the last Golden Eagle seen at 1757. Non-migrants were 6 Turkey Vultures, 5 adult Bald Eagles including 2 pair-flights, 1 resident Sharp-shinned Hawk and 3 Golden Eagles (2a, 1j) with one adult seen displaying. Forty Tundra Swans moved to the NE at 1317.
