March 28 [Day 24] (George Halmazna) The temperature rose to 6C at 1500 from a low of -5C, ground winds were mainly light SW-W occasionally gusting to 14 km/h. Ridge winds were moderate SW and cloud cover was 90-100% stratus all day. There were periods of snow and flurries all day and the eastern ridges were 90-100% obscured to noon when they cleared to 30% and were completely clear after 1500. The western ridges were obscured all day except between 1500 and 1700 when cloud drape reduced to 10%. Because of the weather the first migrant, a Golden Eagle, was not recorded until 1258 but when the last Golden Eagle of the day flew NW at 1947 a total of 193 migrant raptors had been tallied with 49 of the birds moving between 1500 and 1600, 41 between 1600 and 1700 and peak movement of 54 between 1700 and 1800. The flight comprised 14 Bald Eagles (12a, 2j), 10 of which moved between 1600 and 1700, 1 adult Northern Goshawk, 175 Golden Eagles (170a, 5j), 1 light grey morph Gyrfalcon, 1 Peregrine Falcon on undetermined age and 1 Prairie Falcon. After 24.5 days without seeing a falcon it is remarkable that individual birds of three different species moved between 1512 and 1650. For the first time this season, at 1440, the resident pair of Golden Eagles was observed copulating near Olympic Summit on Mount Allan 13.67 hours (267.17) BAEA 14 (110), NOGO 1 (8), GOEA 175 (2188), GYRF 1 (1), PEFA 1 (1), PRFA 1 (1) TOTAL 193 (2337)
