The wind, which was initially S-SE and light, progressively moved to SW and then W steadily increasing in velocity from 20 km/h at 1400 to 30 km/h at 1700 and 40 km/h at 1900; cloud cover after the rain stopped was 70-90% cumulus, altostratus and cirrus giving a perfect viewing backdrop, and the temperature rose to 16C from a starting temperature of 7C. The first raptor migrant, a juvenile Sharp-shinned Hawk, moved by at 1258 and subsequent movement was slow but steady and involved 7 species, with 3 additional non-migrant species seen (Northern Goshawk, Golden Eagle and Prairie Falcon). At 1415, the 2<sup>nd</sup> Swainson’s Hawk of the season, a light morph adult, moved north above the ridge, and the last 2 birds of the day (and of the count) were an adult Peregrine Falcon at 1736 and a juvenile light morph Broad-winged Hawk at 1843. There were no migrant Golden Eagles and the resident pair was seen occasionally after 1700 with the male still gamely displaying. A Warbling Vireo singing at the parking area, two Chipping Sparrows on the ridge and a Barn Swallow flying over the ridge towards the west at 1535 were all seasonal firsts. The non-raptor highlight of the day, however, was a flock of 21 American White Pelicans soaring over the Crowsnest Valley south of the site at 1233 18 of which slowly made their way up the valley with much soaring finally disappearing behind Turtle Mountain at 1250. The other 3 glided back to the east. It was a good last day of the 2008 spring count! 10.5 hours (975.5) BAEA 1 (453), SSHA 1 (196), COHA 2 (39), BWHA 1 (7), SWHA 1 (2), RTHA 2 (227), PEFA 1 (6) TOTAL 9 (4204)</p> <i style=""><span style="font-size: 12pt; font-family: "Times New Roman";">May summary</span></i><span style="font-size: 12pt; font-family: "Times New Roman";"> (compared to 1994-2008 Mount Lorette count averages). We spent 19 days (234.3 hours) in the field during the month and most of the time was spent on the ridge. Four days were significantly affected by inclement weather. The days and hours are 35.7% and 48.5% above average respectively. The combined species count of 339 birds is the second highest RMERF May count (after the 460 at </span><st1:place><st1:placetype><span style="font-size: 12pt; font-family: "Times New Roman";">Mount</span></st1:PlaceType><span style="font-size: 12pt; font-family: "Times New Roman";"> </span><st1:placename><span style="font-size: 12pt; font-family: "Times New Roman";">Lorette</span></st1:PlaceName></st1:place><span style="font-size: 12pt; font-family: "Times New Roman";"> in 1999) and is 141.1% above average.

The sky was ideal for viewing with 30-80% mainly cumulus and cirrus cloud cover. Raptor movement was surprisingly good starting at 0953 with a juvenile rufous morph <i style="">calurus</i> Red-tailed Hawk through to a Cooper’s Hawk at 1810 which was the only adult bird seen today. Nine of the day’s 19 migrants moved between 1234 and 1400, and the total of 5 Golden Eagles comprised 2 subadult and 3 juvenile birds. The resident pair of Golden Eagles was seen soaring together with the male still displaying suggesting that she is not nesting, and is unlikely now to do so at this late juncture. A Cassin’s Vireo singing near the site at 1122 was the first of the season, and a Hoary Elfin was a new butterfly species for the site. Because of today’s strong raptor movement I am planning to watch tomorrow but the start may be delayed as I need to catch up on some sleep. 12.67 hours (965) OSPR 1 (21), SSHA 7 (195), COHA 1 (37), NOGO 1 (137), RTHA 4 (225), GOEA 5 (2981) TOTAL 19 (4195)<o:p></o:p></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4213051643702610616.post-53300275340745171672008-05-17T22:01:00.001-06:002008-05-17T22:01:46.940-06:00<p class="MsoNormal"><b style="">May 17</b> [Day 82] This was the warmest day yet with a high of 23.5C from a low of 14C. Light westerly winds prevailed until 1100 when they progressively increased in velocity and changed to WNW after 1400: by the end of the day they were gusting to 45 km/h. Cloud cover was 60-90% mainly altostratus and cirrus all day. Apart from a juvenile Northern Goshawk at 0824 all the raptor movement was after 1300, and with the exception of 2 subadult Golden Eagles all the migrants were juvenile birds. I was greeted at the site this morning by 9 Bighorn rams, and before the wind increased the day was delightful. Vesper Sparrows were singing for the first time and male Townsend’s Solitaires were in splendid voice during prolonged aerial displays with two birds performing side-by-side on occasion. At least 4 Brown-headed Cowbirds flew high to the west over the ridge during the morning, but the most unusual bird was a male Belted Kingfisher that also flew high to the west at 0935: both species were new for the ridge top.

The cloudless sky was relieved by the development of cirrus cloud between 1000 and 1500 which also gave welcome relief to the eyes. There was again a good late-season count of 19 raptors of 8 species, between a juvenile Northern Goshawk at 1049 and 1854 when a juvenile male Sharp-shinned Hawk flew north with a juvenile female Prairie Falcon with considerable mutual antagonism despite their size difference. All the <i style="">accipiters </i>counted<i style=""> </i>were juveniles as was the only Golden Eagle to move today at 1119: maybe we are finally running out of them. The highlights of the day were 2 Turkey Vultures each of which glided to the north low overhead: a juvenile at 1509 followed at 1648 by an adult. Two male Brown-headed Cowbirds seen by Dawn as she climbed the ridge at 1011 and 2 Violet-green Swallows feeding over the ridge at 1840 were both firsts for the site. Two Snowshoe Hares on the ridge early in the morning were in brown pelage appropriate for the rapidly melting snow conditions, and Western Whites were the first for the season and one of 5 butterfly species found on the ridge today. 12.67 hours (939.8) TUVU 2 (8), SSHA 7 (186), COHA 2 (36), NOGO 2 (133), RTHA 1 (219), GOEA 1 (2971), AMKE 2 (4), PRFA 1 (17), TOTAL 19 (4164)</span>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4213051643702610616.post-80565522249012953282008-05-15T21:43:00.001-06:002008-05-15T21:43:52.790-06:00<p class="MsoNormal"><b style="">May 15</b> [Day 80] The temperature rose to a season-high 17C from a low of 7C, with W-WNW winds gusting between 30 and 65 km/h all day: it was like spending the day inside a hair-drier! Apart from some altostratus low to the horizon before 0900 the day was completely cloudless and finding and keeping birds flying high in the blue in the binoculars with the strong gusty winds took a lot of effort. The day’s total of 21 migrant raptors is not a bad late-season count and again the flight was dominated by Sharp-shinned Hawks and Golden Eagles, all of which were immature as were the Cooper’s Hawk and 2 Northern Goshawks. The female American Kestrel that flew along the ridge at 1820 was only the second for the season and the first since the anomalously early male seen on March 19. Passerine migration was confined to 6 American Pipits and 5 Pine Siskins, and a very noisy pair of copulating <st1:place>Clark</st1:place>’s Nutcrackers at the site at 1610 was briefly diverting.

Of the 17 <i style="">accipiters</i> counted all were juveniles with the exception of 1 adult Sharp-shinned Hawk, and all the 11 Golden Eagles were also juveniles.

The first migrant raptor was a juvenile Golden Eagle at 0831, but the second bird, a juvenile light morph <i style="">calurus</i> Red-tailed Hawk did not appear until 1105 and subsequent movement was only one or two birds an hour until the 3rd juvenile Golden Eagle went north at 1806. The 4 Sharp-shinned Hawks brought the season’s total to 158 passing the highest ever Mount Lorette count for the species of 155 in 1999.

Winds were N-NE gusting up to 25 km/h until 1800 when they shifted to SW-WSW followed by a general clearing. To add to the fun there were occasional thunder showers and at 1435 a simultaneous lightening flash and thunder clap occurred right overhead in a snow pellet white-out which left me tingling for a few minutes. Through all this the temperature only ranged from 0C to 2C all day: it must be spring! There were only two relatively clear periods and in the first a juvenile dark morph Harlan’s Red-tailed Hawk flew by at 0954 and in the second an Osprey went north at 1350. During this second clear period 3 resident adult Golden Eagles flew together to the south. As might be expected songbirds were not much in evidence but 4 Brewer’s Blackbirds flew high over the ridge towards the west at 0836 and the season’s first two Cedar Waxwings were perched west of the ridge at 1340. 12.67 hours (889.3) OSPR 1 (19), RTHA 1 (214) TOTAL 2 (4081)</span>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4213051643702610616.post-27639759391844050452008-05-11T20:55:00.001-06:002008-05-11T20:55:29.548-06:00<p class="MsoNormal"><b style="">May 11</b> [Day 76] I returned home from the Gala at 0030 and after what seemed to be 5 minutes sleep I was climbing the ridge at 0730.

I climbed to the ridge where the wind was NE-E gusting to 40 km/h and -4C which left a little to be desired in the comfort department, and light snow continued to 1310 after which there were periods of snow and flurries to 1810 with generally overcast skies. The clouds began to break by late afternoon, the wind dropped and by 1900 it was calm, sunny and the temperature had risen to 0C. Because of the conditions only three migrants were seen including a juvenile Golden Eagle at 1752 which I first saw soaring well to the south. It slowly glided northward towards me and soared high immediately to the south, then continued to glide to the north. Suddenly I was aware of the bird plummeting vertically to the ground in a hunting stoop just to the south of the site and by running to the edge of the hill I saw it perched on the ground empty-taloned where it was immediately mobbed by two resident ravens. The eagle raised its hackle feathers and looked splendidly fierce for a few seconds before flying to the west with the ravens in hot pursuit, where it soared again before gliding to the north. Meanwhile the Columbian Ground Squirrel that was the intended meal was giving its call note every couple of seconds for several minutes, either as an “all clear” signal or as a “where’s my clean underwear?” call. The most notable non-raptor sighting was 4 American Crows flying west at 1410, the first time in three field seasons that I have seen them above the ridge. 12.75 hours (853.2) BAEA 1 (444), GOEA 1 (2940), PRFA 1 (16) TOTAL 3 (4058) </p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4213051643702610616.post-14310415733488700582008-05-08T21:55:00.000-06:002008-05-08T21:56:04.102-06:00<p class="MsoNormal"><b style="">May 8</b> [Day 73] I again watched from the Valley View site and with moderate to strong W winds on the ridge all day this time it proved to be the right decision.

Cloud cover was 100% altostratus and cumulus all day giving rather gloomy conditions and the temperature started at 5C and rose to 11C. The calm conditions precluded early movement and the first bird, a juvenile Northern Goshawk, wasn’t seen until 1133. After that, however, movement was steady until 1500 when it slowed to a trickle until 1844 when the last 4 Golden Eagles of the day came through in a 12 minute period. The last bird of the day was a juvenile Bald Eagle at 1929. Eleven of the day’s 36 migrants moved between 1200 and 1300 which included the 4,000<sup>th</sup> migrant of the season which was a Golden Eagle at 1218, and an11 minute period that saw the passage of 3 Turkey Vultures, an adult dark morph “Harlan’s” Red-tailed Hawk, a juvenile Golden Eagle and an adult Peregrine Falcon. The Golden Eagle count comprised 2 subadults and 11 juveniles, and the resident pair was seen soaring together on occasion, but never near a visible nest site. On a couple of occasions the male vigorously <span style=""> </span>mobbed a resident Red-tailed Hawk only to have the tables quickly reversed with the eagle beating a hasty retreat closely pursued by the hawk! The recent list of bird species apparently out of place on a mountain ridge was augmented at 1334 by our first Great Blue Heron flying high to the north just east of the ridge. The first Yellow-rumped Warbler of the year was singing at 0745, but the most spectacular bird of the day was undoubtedly a male Dusky Grouse in full display strutting with a fully fanned tail and expanded scarlet nuchal sacs set off in their coronas of snow white exposed under-feathers. 12.83 hours (807.7) TUVU 3 (6), OSPR 1 (18), BAEA 3 (442), NOHA 1 (25), SSHA 7 (147), COHA 1 (26), NOGO 3 (123), UA 1 (8), RTHA 2 (213), GOEA 13 (2928), PEFA 1 (5) TOTAL 36 (4030) </p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4213051643702610616.post-80364906172797417932008-05-04T23:09:00.001-06:002008-05-04T23:09:14.229-06:00<p class="MsoNormal"><b style="">May 4</b> [Day 69] (Bill) Winds were westerly all day gusting to 30 km/h by mid-afternoon, and cloud cover ranged from 2%-100% altostratus and altocumulus cloud cover giving sunny skies, or hazy sunshine after 1300. The temperature rose to a very pleasant 14C from a low of 4C. Raptor migration was slow but steady for much of the day with 9 of the day’s 28 birds occurring between 1600 and1700. The highlight of the day was the 11<sup>th</sup> Ferruginous Hawk of the season, a light morph adult. Only 3 Golden Eagles were recorded: 2 subadults and 1 juvenile. The other highlights were both species not expected to be seen on a mountain ridge at 1900 m and both were new species for the site.

Probably because of the light winds raptor movement was very sporadic between 1133 and 1827 with only 13 birds counted including 5 Golden Eagles (2 subadults, 1 juvenile and 2 of indeterminate age). A calling Mourning Dove early in the morning just above the parking area was a new species for the study area, and 3 Brewer’s Blackbirds flying above the ridge to the WSW at 0903 were a first for the site.

The temperature rose to 10.5C from a low of 0C, and 20-60% cumulus cloud cover for most of the day made locating birds relatively easy although unlike yesterday few were close to the ridge. Movement was very sporadic with most birds moving during periods of SW winds, with a period between 1225 and 1510 with no movement at all. Notable were the 4<sup>th</sup> Broad-winged Hawk (adult light morph) and 13th “Harlan’s” Red-tailed Hawk (adult dark) of the season and all 11 migratory Golden Eagles were immature, 1 subadult and 10 juveniles, the last of which came through at 1911. When I arrived at the ridge top the site was occupied by 6 Dusky Grouse and males were heard hooting throughout the day. New species for the season were Savannah Sparrow and a singing Ruby-crowned Kinglet, and Tree Swallow and a winnowing Wilson’s Snipe were recorded for the first time from the ridge.

Cloud cover was cumulus, cirrus and cirrostratus gradually increasing from 5% early in the morning to 80% at the end of the day providing an excellent observing backdrop. Again there was no early movement and the first bird, an adult Northern Harrier, didn’t appear until 1056 and steady migration only started after noon after which it was steady until the last 2 Golden Eagles glided north at 1935. Many of the birds moved low overhead giving ample opportunity to study details of plumage. Immature Golden and Bald Eagles have dominated the flight for the last couple of weeks, but now young birds of other species are becoming more common with all 4 Red-tailed Hawks, 4 Northern Goshawks and 4 of the 17 Sharp-shinned Hawks being juveniles. All the 26 migrant Golden Eagles were immature: 6 subadults and 20 juveniles. The 3<sup>rd</sup> Broad-winged Hawk of the season, a light morph adult, flew low overhead at 1739. For the first time this season I observed a resident Golden Eagle carrying prey (probably ground squirrels) towards the west on two occasions, probably a male going to present food to the female: maybe breeding is getting closer! On the ridge Townsend’s Solitaires were anything but solitary as I counted 19 there, many of which were singing. For the first time there was a variety of finches moving: 46 Grey-crowned Rosy-Finches, 1 Pine Grosbeak, 2 Red Crossbills, 3 White-winged Crossbills and a single Pine Siskin. 13 hours (754.2) OSPR 2 (16), BAEA 2 (434), NOHA 2 (22), SSHA 17 (130), COHA 4 (22), NOGO 4 (114), BWHA 1 (3), RTHA 4 (201), GOEA 26 (2896), MERL 1 (17), PRFA 1 (13) TOTAL 64 (3929)</p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4213051643702610616.post-92178593590081269112008-04-30T22:54:00.001-06:002008-05-19T22:41:28.543-06:00<p class="MsoNormal"><b style="">April 30</b> [Day 65] So much for the weather forecast! I spent the day on the ridge after all, where it was sunny all day with 10-40% cumulus cloud cover. The wind initially was from the NW gusting 70 km/h and with a starting temperature of -4C it felt a little chilly. The wind progressively backed to WNW and finally W and moderated to gusts of 25-40 km/h as the pressure rose rapidly after 1500, and the temperature reached a high of 3C. As yesterday early movement was slow with the first bird, a juvenile Golden Eagle appearing at 0942 and by 1300 only 6 migrants had passed. Subsequent movement was steady peaking at 14 birds between 1500 and 1600 and the last bird, the first Swainson’s Hawk of the season (an adult light morph), moved north at 1855. This is the first time the species has been recorded in April on an RMERF count. Other notable birds were the second Broad-winged Hawk of the season (a light juvenile) and the 5<sup>th</sup> Gyrfalcon (an adult grey morph, probable female) which flew low overhead giving a splendid view in the bright sunlight. Two of the Red-tailed Hawks were dark morph “Harlan’s Hawks” (one a juvenile), and the 21 migrant Golden Eagles comprised 5 subadults and 16 juveniles but there was no sign of the resident birds today. Grey-crowned Rosy-Finches continue to move in good numbers with 289 flying north along the ridge with the largest flock containing about 150 birds. 12.75 hours (741.2) SSHA 15 (113), NOGO 1 (110), UA 1 (5), BWHA 1 (2), SWHA 1 (1), RTHA 4 (197), UB 1 (3), GOEA 21 (2870), MERL 2 (16), GYRF 1 (5), PRFA 1 (12) TOTAL 49 (3865)</p> <p class="MsoNormal"><i style="">April summary</i> (compared to 1993-2008 Mount Lorette count averages).

The combined species total of 1212 was the 3<sup>rd</sup> highest total ever (+44.2%) and included 17 species: the only species not recorded was American Kestrel, only the second time it has been absent from an April count. The Golden Eagle count of 646 was 5.8% above average making it the 6<sup>th</sup> highest April count and the 121 Bald Eagles were 33.6% above average and the 3<sup>rd</sup> highest April count.

Rain persisted until 1350, after which the rest of the day was dry, with the temperature at the base of the ridge reaching 9C. Ridge winds were moderate westerly all day, and mid afternoon was sunny with 60-70% mainly cumulus cloud before the clouds thickened again after 1700. A single Sharp-shinned Hawk that moved along the ridge at 0816 was the only migrant before the rain started, and movement only really began at 1410 after which there was a fairly steady stream of birds until the last Bald Eagle went north at 1924. Compared to the last few days there was little specific variety and the flight was dominated by Golden Eagles, the total of 29 comprising 1 adult, 5 subadults and 23 juveniles. Again compared to recent days the resident Golden Eagles were hardly in evidence today. The forecast for the next two days is for overcast conditions with rain or snow so I shall probably watch from the Valley View site (if at all!) until Friday. 12.67 hours (728.5) BAEA 2 (432), NOHA 1 (20), SSHA 6 (98), NOGO 1 (109), RTHA 4 (193), GOEA 29 (2849) TOTAL 43 (3816) </p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4213051643702610616.post-39510554610176793792008-04-28T22:52:00.001-06:002008-04-28T22:52:52.269-06:00<p class="MsoNormal"><b style="">April 28</b> [Day 63] We finally made it to the ridge top to observe for the first time this season with the site snow-free but with several metres of snow packed on the lee side of the ridge. Even at 1900 m the temperature rose to 13.5C from a low of 6C, and it was mainly sunny with 30-60% cumulus cloud cover for most of the day. The wind was westerly all day gusting to around 40 km/h until 1715 after which gusts were in the vicinity of 70 km/h, and after 1615 smoke haze developed which lingered until the end of the day. Despite the wind it was good to be back up high and to appreciate again close views of migrating raptors, and there were fairly good numbers to see with 67 birds of 11 species (and 2 additional subspecies) moving: the 3<sup>rd</sup> highest count this month. The movement started late with only 4 birds seen by 1100 and the first Golden Eagle migrant didn’t appear until 1331 but then movement was steady until the passage of the last bird at 1854. The 5 Northern Harriers (all adults: 2 males and 3 females) was the highest count this season, and one of the day’s 8 Red-tailed Hawks was an adult “Krider’s Red-tailed Hawk” which glided close along the ridge at 1654 for a first site record. A juvenile light morph Ferruginous Hawk at 1405 was the 10<sup>th</sup> record of the species this season, and all the 22 Golden Eagles were immature: 4 subadults and 18 juveniles. The closest birds of the day, however, were the <i style="">three</i> resident Golden Eagles that glided by moving low to the north over the ridge at 1848, and despite much display by the male (or males) during the day, the female still shows little sign of nesting.

The day’s count of 49 migrant raptors was reasonable for this stage of the season but after yesterday’s cornucopia it seemed rather plodding even though 11 species of migrant were tallied. Highlights again were the 3<sup>rd</sup> Turkey Vulture (adult) and 4<sup>th</sup> Peregrine Falcon (adult) of the season, and the total of 22 Golden Eagles comprised 2 adults, 6 subadults and 14 juveniles. Both resident Golden Eagles were on the aerie for about 10 minutes just before 0800 and again for 3 minutes at 1343, but spent most of the day away from the site.

The combined species count of 146 birds was the highest since March 21 and the hourly counts at 1300-1400, 1400-1500 and 1500-1600 were progressively the highest yet for April at 23, 25 and 26 respectively. The counts for Osprey (4), Sharp-shinned Hawk (27), Cooper’s Hawk (5) and Red-tailed Hawk (24, including 2 “Harlan’s Hawks”) were the highest so far this season, and notable were the 2<sup>nd</sup> Turkey Vulture (adult), 3<sup>rd</sup> Peregrine falcon (adult) and 4<sup>th</sup> Gyrfalcon (juvenile grey morph) of the season. The total of 73 Golden Eagles was the highest daily count since March 21 and comprised 6 adults, 11 subadults and 56 juvenile birds.
