Beaver Mines May 03, End of Spring 2020 Count

Sunday, May 03 Beaver Mines [Day 69] 0615-2045 (Peter Sherrington and Hilary Atkinson). The temperature at 0615 was 9C, periodic light rain between 0645 and 1115 reduced the temperature to 6C at 1000 and 1100; it reached the day’s high of 10.5C at 1400 but snow and sleet flurries between 1435 and 1513 reduced it to 8C at 1500; it rose again to 10C at 1600 and 1700 and then gradually fell to 5C at 2045. Winds were strong WSW all day, 30-50 gusting 70 and occasionally 80 km/h, and cloud cover was 100% stratocumulus to 1300 after which it was mainly cloudless with up to 40% cumulus briefly moving from the SW, with the exception of around 1500 when it was 100% stratus that produced snow flurries. Despite the variable weather observation conditions were generally good but the last day of the count produced only 7 migrants of 4 species between 1239 and 1741 that occurred in two small clusters: 4 birds between 1239 and 1352 and 3 birds between 1712 and 1741. The count was 1 juvenile Bald Eagle, 3u Sharp-shinned Hawks, 1 juvenile Cooper’s Hawk and 2 Broad-winged Hawks (1 juvenile dark morph and 1 adult light morph that was the last bird of the spring 2020 count at 1721). Resident birds were 4 Bald Eagles (2a, 2j) that fed on the valley floor just after noon, 1 briefly sighted adult male Northern Harrier at 1239, 1 Red-tailed Hawk hunting at 1554 and a pair hunting at 1850, and a single adult Golden Eagle that hunted the ridge at 0755 and 1804. Other birds were 2 Canada Geese, 2 Cinnamon Teal, 5 Mallards, 1 drumming Ruffed Grouse, 12 Rock Pigeons, 2 Mourning Doves, 1 male Calliope Hummingbird, 2 Sandhill Cranes, 2 Wilson’s Snipe, 1 Red-naped Sapsucker, 2 Downy Woodpeckers, 1 Hairy Woodpecker, 1 Steller’s Jay, 2 Blue Jays, 2 Black-billed Magpies, 35 American Crows, 21 Common Ravens, 6 Tree Swallows, 2 Mountain Chickadees, 1 Ruby-crowned Kinglet, 6 American Robins, 56 European Starlings, 19 Evening Grosbeaks, a flock of 14 Cassin’s Finches (5 males and 9 females), 3 White-crowned Sparrows (2 oriantha that is the local breeding race and 1 migrant intergrade orianthagambelii), 12 male Red-winged Blackbirds, 1 male Brown-headed Cowbird that is the first for the season, and 12 Common Grackles (10 males, 2 females).

Winds were moderate SSW-W all day, 12-20 km/h to 0915, then 20 gusting to 35 km/h to 1700 and finally 10-20 km/h for the rest of the day. It was mainly cloudless with periods of up to 20% altocumulus to 1430 after which it was 60-100% cumulus, altostratus and cirrus for the rest of the day. It was a pleasant day with generally good viewing conditions but only 13 migrant raptors of 6 species were seen between 1044 and 1723 that comprised 2 adult Turkey Vultures, 4 Bald Eagles (2a, 1sa1, 1j), 1 adult Sharp-shinned Hawk, 1u Cooper’s Hawk, 2 juvenile light morph calurus Red-tailed Hawks and 3 Golden Eagles (1sa, 2j). Non-migrants were 7 Bald Eagles (6a, 1j) that glided high to the SE between 1157 and 1245, a number that is very similar to the 6 Bald Eagles (5a, 1j) that glided high to the N between 1607 and 1856 yesterday. Five adult resident Red-tailed Hawks were conspicuous between 0923 and 1909 and, unlike yesterday, there was much interaction between up to 4 birds that involved displays and some spectacular vertical stoops from a considerable height to a lower-flying bird. Other birds were 9 Canada Geese, 4 Mallards, 11 Rock Pigeons, 2 Mourning Doves, 1 male Rufous Hummingbird, 1 male Calliope Hummingbird that was the first for the season, 3 Sandhill Cranes, 6 Wilson’s Snipe, 1 Red-naped Sapsucker, 2 Downy Woodpeckers, 1 Hairy Woodpecker, 1 Steller’s Jay, 2 Blue Jays, 2 American Crows, 12 Common Ravens, 16 Tree Swallows, 3 Black-capped Chickadees, 4 Mountain Chickadees, 8 American Robins, 12 European Starlings, 20 Evening Grosbeaks, 3 Purple Finches (1 subadult male, 2 females), 6  Cassin’s Finches (3 male and 3 female), 14 male Red-winged Blackbirds and 5 Common Grackles (3 male, 2 female).

Beaver Mines, April 28

Tuesday, April 28 Beaver Mines [Day 64] 0700-2030 (Peter Sherrington and Hilary Atkinson). The temperature at 0700 was 4C, the high at 1700 was 15C and it was 12C at 2030. Yet again the winds were W-WSW all day, 35-45 gusting 55-60 km/h, and it was cloudless to 1440 after which cloud cover was 20-40% altocumulus and lenticular that gave excellent observing conditions. The conditions were also conducive for raptor migration after 1100 with a total of 33 birds moving fairly steadily between 1108 and 1930 comprising 14 species, which equals the season high species count and includes a rare “grand-slam” of all 5 falcon species. The count was 1 adult Turkey Vulture, 1 Osprey, 8 Bald Eagles (6a, 1sa2, 1 sa2), 4 Sharp-shinned Hawks (2a, 2u), 1 juvenile Cooper’s Hawk, 1 adult light morph Swainson’s Hawk, 2 adult light morph calurus Red-tailed Hawks, 1 dark morph Rough-legged Hawk, 6 juvenile Golden Eagles, 1 female American Kestrel, 2 male columbarius Merlins, 1 juvenile female grey morph Gyrfalcon that flew directly overhead at 1256, 2 adult Peregrine Falcons (1 male, 1 female) and 2 female Prairie Falcons. The highest hourly count was 8 birds between 1100 and 1200, and 3 other hours saw the passage of 5 birds. Residents were again a pair of Northern Harriers with the male seen displaying at 1711, and 2 pairs of Red-tailed Hawks seen regularly between 0903 and 1834 with males seen displaying at 1557 and 1710.
