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.

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). Birds moved steadily all day and the highest hourly counts were 10 (1000-1100, 1400-1500 and 1800-1900).
