Winds were W-WSW all day 10-20 gusting 30 km/h, and it was cloudless to 1500 after which 20-60% thin altostratus and altocumulus developed. A season-high total of 20 migrant raptors of 4 species moved to the N or NW between 0954 and 1720 that comprised a season-high 12 Bald Eagles (6a, 2sa, 3j, 1u), the season’s first migrant Northern Goshawk (an adult), 6 adult Golden Eagles and the first Gyrfalcon of the season, a grey morph of unknown age. Ten of the birds migrated between 1404 and 1453 raising hopes of a significant movement, but no further birds were seen until 1720 when the last 2 Bald Eagles soared and glided to the north.
