March 22 [Day 31] Apart from 10% cumulus at 0800 and a wash of thin cirrostratus after 1900 the sky was cloudless all day. Despite the sunshine the temperature only rose to 4C from a low of -4C, and winds were moderate NW-SW becoming light after 1800. The first migrant flapped heavily to the north at 0916, and it was only after 1030 that air conditions allowed buoyant gliding flight. Movement thereafter was steady, albeit sporadic, with periods of up to 20 minutes with no birds followed by a concentrated burst of migrants. Eleven birds moved after 1900 with the last Golden Eagle gliding north at 1935. The total of 21 Bald Eagles was the second highest total for the season so far and the highest since March 9. An adult dark morph Harlan’s Red-tailed Hawk at 1828 was the first for the season. Display activity of the resident Golden Eagles was again concentrated around the Bluff Mountain nest although neither bird visited it. Most spectacular was both birds soaring and interacting above Bluff Mountain at 0955 while being harassed by a Prairie Falcon that is also resident on the mountain. Passerine migrants were 28 Grey-crowned Rosy-Finches and 90 Bohemian Waxwings, 60 of which flew high to the north along the ridge just before 1930. 12 hours (326.3) BAEA 21 (247), NOGO 4 (46), RTHA 1 (8), GOEA 105 (1732) TOTAL 131 (2059)

Mount Lorette (Joel) It was cloudless all day with calm or light winds in the valley and temperatures that ranged from -10C to 5C. Movement started at 1140 but the main movement did not start until after 1600 with the last bird seen at 1856. Single records of Rough-legged Hawk and Merlin were firsts for the season. 11.5 hours (241.2) BAEA 3 (50), NOGO 1 (2), RLHA 1 (1), GOEA 66 (926), MERL 1 (1) TOTAL 72 (984)
