The Mt. Lorette Raptor Count has now begun. Welcome to another exciting year of watching the birds migrate! We most enjoy having visitors to the site and assisting in the sightings. First official day of counting began on 18th February 2007. Follow the daily movement of the raptors on this blog updated daily by Peter Sherrington.

I tallied a total of 48 bird species today, the second highest for the season, including the first 4 White-crowned Sparrows [# 89], 4 days later than the long term average arrival date, and a female Rusty Blackbird [#90]. (14.25 hours: 839.7) TUVU 3 (3), OSPR 3 (4), BAEA 1 (206), SSHA 10 (50), COHA 5 (14), NOGO 1 (22), UA 3 (6), RTHA 2 (52), GOEA 27 (2117), AMKE 1 (5), PEFA 1 (2), PRFA 1 (4) TOTAL 58 (2528)

DAY 68 (April 28) (Cliff Hansen, Ron Dutcher) The rain continued to around 1030 with the ridges obscured until after 0900, then it progressively cleared until after 1900 it was almost cloudless. The temperature rose to 12C from a low of 4C and SW-W winds gradually diminished throughout the day. Once again raptor movement was almost non-existent with only one juvenile GOEA moving at 1605. There was an influx of 16 Northern Shovelers at Lorette Ponds and a flock of 10 Savannah Sparrows in the Hay Meadow was the highest number so far this year. (12.66 hours: 825.4) BAEA 1 (205), SSHA 1 (40), GOEA 1 (2090) TOTAL 3 (2470)

DAY 66 (April 26) Upper winds were moderate SW backing to strong W after 1200, with Cu and Ac cloud giving an excellent observation backdrop, and the temperature rose to 11C from -3C. Raptor movement was again slow and very sporadic including single SSHA, COHA and NOGO passing in a 3-minute period (moving in taxonomic order!) and a group of 3 juvenile GOEA just before 1900. An adult male

DAY 56 (April 13) Chinook conditions prevailed all day with moderate to strong SW winds and temperatures rising to 10C from a low of 4C. Once again raptor migration was slow and sporadic and was over by mid-afternoon. Of the 10 GOEA recorded only 1 was an adult. There were also very few non-raptor species and song was almost non-existent: a flock of 30 Common Redpolls were the only passerine migrants noted. A single Wood Frog singing near the site at 1745 was the first heard this year. (14 hours: 661.8) BAEA 2 (182), NOHA 1 (2), RTHA 1 (29), GOEA 10 (1904) TOTAL 14 (2171)

DAY 54 (April 11) At 0100 the sky was clear and a blanket of stars but by 0545 it was snowing again which persisted to 1000 (1cm fresh) and flurries continued to 1430. The temperature rose to 4C from a low of -2C, and winds were once again mainly from the N or NE gusting to 20 km/h after calm conditions prevailed while the snow was falling. I saw a total of 7 migrant raptor species but, unfortunately, a total of only 9 raptors and 3 of those came in a 12 minute period just after 1100! The 3 falcons were an adult male columbarius MERL, a male grey morph GYRF and an immature female PRFA. As soon as the snow finished a couple of Violet-green Swallows were feeding at the site and there were 5 more there at 1725, and a Northern Rough-winged Swallow flew to the south at 1802. Three Northern Shovelers (2m, 1f) [#70] and a male Lesser Scaup [#71] at the Ponds early in the morning were both the earliest ever records for the area by 3 days. At 0750 a Winter Wren was heard singing for the first time this season, beautiful as ever in the gently falling snow, but without the richness that will doubtless develop with practice. (12.75 hours: 634.3) BAEA 3 (174), RTHA 1 (26), RLHA 1 (12), GOEA 1 (1889), MERL 1 (7), GYRF 1 (3), PRFA 1 (2) TOTAL 9 (2142)

DAY 50 (April 07) Again most of the morning was calm with high St cloud burning off by noon leaving a cloudless afternoon and a temperature that climbed to 5.5C from a low of -7C. The morning was really spring-like for the first time with a significant influx of songbirds overnight including a flock of 80 bickering male American Robins, 3 Tree Swallows and 3 Violet-green Swallows, the first swallows since last weekend. The daily bird species count reached 40 for the first time this year although, oddly, no new species were recorded. The morning saw a steady if slow progression of a variety of raptors in the calm conditions, then at 1133 the winds instantly picked up from the NE then from the N gusting to 30 km/h and as yesterday almost everything stopped moving in the afternoon with the exception of a few BAEA and a single adult male MERL, the first of the subspecies richardsoni for the season. A single Milbert’s Tortoiseshell at the site was the 3rd butterfly species of the year. (13.33 hours: 587.7) BAEA 11 (587.7), SSHA 4 (10), COHA 1 (3), RTHA 3 (19), RLHA 3 (6), GOEA 8 (1826), MERL 1 (4) TOTAL 31 (2033).

DAY 43 (March 31) Springtime in the Rockies with light to moderate snow for most of the day, temperatures ranging from 1C to -1.5C and N to NE winds gusting to 30km/h. The upper winds, however, were SW to W all day, but the ridges were enveloped in cloud for most of the day. A brief clearing of the clouds mid-valley in mid-afternoon led to a short-lived raptor movement down the valley, with birds getting some lift from thermals probably generated from the Nakiska Road 1 km to the south. A single RLHA was the first of the season [#57] and 12 days later than average. The snow put good numbers of Dark-eyed Juncos down in the meadow, and gave me time to have a good look at them: 108 montanus, 20 cismontanus and 1 hyemalis (the first for the season). During the month of March we spent the full 31 days in the field for the third consecutive year and the 385.3 hours was 23.6% above average. Despite this the total raptor count was only 1893, 30% below average and the first March count below 2000. Both Bald Eagles (91: -22.7%) and Golden Eagles (1782: -30.4%) were significantly below average, with the GOEA count being the lowest ever, even below that of the 1950 counted in 2002 when bitterly cold weather meant that significant movement did not start until March 18. (11.66 hours: 509.3) BAEA 3 (101), RLHA 1 (1), GOEA 5 (1785) TOTAL 8 (1906)
