Ground winds were variable but mainly NE to NW occasionally gusting 60 km/h but mainly 5-15 km/h, and ridge winds were strong WNW all day. Cloud cover was 80-100% mainly cumulus, altostratus and lenticular giving good to excellent observing conditions.

Golden Eagles dominated the flight with 122 birds comprising 94 adults, 10 subadults, 15 juveniles and 3 birds of unknown age, and 11 Bald Eagles comprised 6 adults, 1 subadult and 4 juveniles. Highlights were the season’s 6th Gyrfalcon at 1223 (a grey morph of undetermined age) and an adult Peregrine Falcon at 1520 which raised the reason’s record count to 47. 11 hours (761.12) BAEA 11 (263), NOGO 3 (121), GOEA 122 (3669), GYRF 1 (6), PEFA 1 (47) TOTAL 138 (6035)
