RMERF counts, April 18
Thursday, April 18 Mount Lorette [Day 47] 0715-2010 (Blake Weis, assisted by Rachel MacKay). The temperature at 0715 was 5C, the high was 14C from 1700 to 1900 and it was 12C at 2010. Ground winds were W-SW all day, 2-5 gusting 15 km/h to 0900 and then 5-10 gusting to 32 km/h for the rest of the day, while ridge winds were moderate to strong NW all day. Cloud cover was initially 40% altocumulus, lenticular cirrus and altostratus that gradually spread to 70% at 1100; between 1100 and 1300 it was 80-90% cumulus, altocumulus, altostratus, cirrus, cirrocumulus and cirrostratus, at 1300 and 1400 it was 100% altostratus and cumulus and for the rest of the day it was variable 50-80% cumulus, altocumulus, altostratus and cirrus with minor stratocumulus developed to the west. The variety of cloud forms was not matched by the number of raptor migrants as again only two were seen: 1 adult light morph calurus Red-tailed Hawk that flew north from the Fisher Range at 1458 and an immature Bald Eagle that flew from the south face of Mount Lorette to Mount McGillivray and on to the NW at 1844. Resident birds were a pair of Red-tailed Hawks soaring over Hummingbird Plume Hill and single birds, probably of the same pair, that hunted north of the site, and an adult Golden Eagle that flew low from Mount Lorette to the Fisher Range at 1140. Other birds noted in the area were 3 Canada Geese and a pair of Mallards on the river, 3 drumming Ruffed Grouse, 1 Hairy Woodpecker, 3 Northern Flickers, 1 Canada Jay, 1 American Crow, 7 Common Ravens, 3 Black-capped Chickadees, 2 Mountain Chickadees, 2 Boreal Chickadees, 2 Red-breasted Nuthatches, 1 American Dipper seen at Troll Falls, 1 Golden-crowned Kinglet, 1 singing Ruby-crowned Kinglet, 1 male and 2 female Mountain Bluebirds, 2 singing Varied Thrushes, 15 American Robins, 2 American Pipits, 12 White winged Crossbill, 2 Pine Siskins, 1 Fox Sparrow that sang only in the morning, 1 singing Song Sparrow, 10 Dark-eyed Juncos, 3 of which were montanus, the first Western Meadowlark of the season and 1 male Red-winged Blackbird.

Wednesday, April 17 Mount Lorette [Day 46] 0715-2045 (Cliff Hansen, assisted by Rick Robb and Chris Hunt). The starting temperature was 3C, the high at 1700 was 11C and it was 7C at the end of observation. Ground winds were SW all day 0-5 gusting 20 km/h and up to 35 km/h after 1700, while ridge winds were moderate to strong W-NW in the morning that became NW to 1700 after which they were strong NW for the rest of the day. Cloud cover was initially 80% cumulus that brought light snow flurries and was then 90-60% cumulus for the rest of the day. The ridges were clear all day and observing conditions were good throughout, but the only migrants seen were a subadult Golden Eagle that glided high from the Fisher Range to above Mount Lorette at 1618 and an unaged Golden Eagle that glided very high on the same route at 1940.

Ground winds were S-SW 0-5 gusting 15 km/h to 1300, variable SW-W-NW 0-5 gusting 20 km/h between 1300 and 1500, and then W-SW 0-5 gusting 25 km/h for the rest of the day. Ridge winds were SW all day, light to moderate to 1300, moderate to 1900 then light to moderate for the rest of the day. Cloud cover was 80-90% cirrus and cirrostratus to 1100 that reduced to 70% altocumulus and cirrus at 1300, and 20% altocumulus at 1600 after which it increased again to 90% altostratus, altocumulus, cirrus and cirrostratus for the rest of the day.

Monday, April 15 Mount Lorette [Day 44] 0715-1915 (George Halmazna, assisted by Dan Parliament). The temperature was -3C at the start, rose to a high of 5.5C at 1500 and was 3C at the end of observation. It was calm to 0900 after which ground winds were SW all day, 5-15 km/h to 1800 and 2-10 km/h for the last two hours, while ridge winds were moderate SW all day. Cloud cover was 80-100% cirrocumulus, cirrostratus, altostratus, cumulus and stratus all day that produced snow flurries in the west to 1800 that only occasionally reached the site. All ridges were clear in the morning after which the west was 20% obscured except between 1600 and 1700 when it was 90% obscured, and the east was 30% obscured during the same period and 10-20% obscured for the rest of the afternoon apart from the last hour when it cleared. There was a disappointing migration of only 8 eagles: 1 juvenile Bald Eagle and 7 Golden Eagles (5a, 2u) that moved between 1245 and 1800 with a maximum hourly count of 3 (1 Bald and 2 Golden Eagles) between 1300 and 1400, and 2 Golden Eagles moved between 1700 and 1800. The first three birds were initially located over Skogan Pass from where they glided to Pigeon Mountain and the rest glided high from the northern end of the Fisher Range to Mount Lorette. Resident and non-migrant birds were an adult Bald Eagle that flew to the south, 1 adult Northern Goshawk, 1 adult light morph calurus Red-tailed Hawk and the resident pair of Golden Eagles. Other birds in the area were 3 Canada Geese and 5 Mallards on the river, 1 male Common Merganser flying above the river, 3 drumming and 1 seen Ruffed Grouse, a pair of Northern Flickers, 1 Canada Jay, 7 Common Ravens, 7 Black-capped Chickadees, 4 Mountain Chickadees, 2 Boreal Chickadees, 4 Red-breasted Nuthatches, 1 male Mountain Bluebird, 1 singing Varied Thrush, 13 American Robins, 1 Song Sparrow and 10 singing montanus Dark-eyed Juncos.

The starting temperature was 1C but fell to 0C at 0800, reached a high of 7C at 1600 and 1700 and was 2C at the end of observation. Ground winds were SW-NW 0-3 km/h to 0800, and then SSE-SW 5-10 km/h for the rest of the day with a maximum gust of 36 km/h at 1500; ridge winds were WSW all day, moderate to 1400 and then moderate to strong. Cloud cover was 80-100% cumulus and altostratus to 1500, 30% cumulus at 1600 and then 60-70% cumulus and stratus for the rest of the day. There were very light snow flurries between 1100 and 1400 and a snow squall between 1430 and 1500, but the east was clear and the west was 10-20 % obscured all day. There was a slow but steady raptor movement of 14 birds of 3 species between 0912 and 1927 with 5 hourly periods having 2 migrants and 4 producing single birds. The count was 1u Bald Eagle, 1 unidentified Accipiter, 11 Golden Eagles (2a, 1sa, 5j, 3u) and 1 unidentified eagle. All birds glided high to very high above the Fisher Range to Mount Lorette with the exception of one Golden Eagle that glided directly to Skogan Pass and on to the NW. Three resident adult light morph calurus Red-tailed Hawks soared amicably together at the southern end of Hummingbird Plume Hill at 1645, 2 Bald Eagles (1a, 1sa) moved towards the south and three single resident Golden Eagles (2a, 1j) were seen flying at 1408, 1533 and 1941 but no displays were evident. Other birds recorded in the area were 3 Canada Geese, 2 pairs of Mallards and a pair of Common Goldeneyes all on the river, 7 Common Mergansers flying to the north above the river, 1 drumming Ruffed Grouse, 4 unidentified white-headed gulls that flew north above the eastern part of the valley, 2 Northern Flickers, 1 American Crow, 25 Common Ravens, 1 Black-capped Chickadee, 2 Mountain Chickadees, 2 Boreal Chickadees, 1 Red-breasted Nuthatch, 1 singing Varied Thrush, 6 American Robins, 1 Fox Sparrow that sang in the early morning and was not heard again, and 2 Dark-eyed Juncos, 1 of which was montanus.
