September 23 [Day 28] The air remained cold all day with the temperature briefly reaching a high of 5C from a low of 0C, and with the wind gusting from the W to 50 km/h in the afternoon it felt even cooler. There were a few light flurries in the early morning, but after noon the morning stratocumulus gave way to progressively diminishing cumulus cloud that was down to 20% by 1900. With the exception of an early Osprey at 0954, raptor movement didn’t really get underway until after 1100 and was then steady until 1647 when movement almost ceased until after 1800 when the second juvenile Peregrine Falcon of the day moved south and the last birds of the day were a group of 5 Golden Eagles soaring high at 1828 before gliding to the south. The 5 Ospreys, 4 of which migrated between 1418 and 1459, equaled the season’s highest daily count and established a new seasonal high for the site of 19. The 28 Golden Eagles is the highest count so far this season and the evening flourish suggests that the main movement is about to start. All 11 Red-tailed Hawks were light morph calurus: 9 adults and 2 juveniles, and one of the 2 Broad-wing Hawks was a juvenile dark morph bird. Passerine movement recovered some of its momentum and included the first Pine Grosbeaks (5) of the season, appropriately first seen during one of the early morning snow flurries, and a single flock of 35 Mountain Bluebirds flying high to the south at 1755. 12.25 hours (317.17) OSPR 5 (19), SSHA 20 (631), COHA 4 (144), NOGO 2 (54), BWHA 2 (16), RTHA 11 (95), GOEA 28 (172), PEFA 2 (9), PRFA 1 (6) TOTAL 75 (1257)
