April 4 [Day 30] (George Halmazna) The temperature high was 5C at 1500 from a morning low of 0C, and was 3C at the end of the day. Ground winds were S-SE 5-12 km/h until 0900 when they backed to SW for the rest of the day generally 5-15 occasionally gusting 50 km/h, and ridge winds were SW moderate to strong with a peak gust of 143 km/h at 0800 but then decreasing with gusts between 40 and 70 km/h. Cloud cover was 100% stratus and altostratus changing to 40% cumulus 1100 that reduced to 30% at 1500 and increased again to 60% with snow flurries in the late afternoon. The eastern ridges were clear all day, but the west was obscured by snow and cloud between 40 and 90% for most of the day. There was another fairly strong raptor movement with 104 birds moving between the day's first Golden Eagle at 0749 and the last at 1819, with peak movement occurring between 1000 and 1100 with the passage of 31 birds, 29 of which were Golden Eagles. The strong morning and early afternoon movement became sporadic and diminished after 1400. The flight comprised 8 Bald Eagles (4a, 4j), 1 Northern Harrier of undetermined age and sex, a season high tally of 4 Sharp-shinned Hawks (1a, 3u), 1 adult light morph calurus Red-tailed Hawk, 89 Golden Eagles (83a, 2sa, 4j) and 1 Prairie Falcon. 14 hours (344.25) BAEA 8 (145), NOHA 1 (3), SSHA 4 (9), RTHA 1 (12), GOEA 89 (2750), PRFA 1 (2) TOTAL 104 (2960)
