April 19 [Day 45] (George Halmazna) Today was marginally warmer with a high of 1C at 1300 from a starting low of -15C and it was -1C at the end of the day. Ground winds were calm or light for much of the day except between 1500 and 1530 when the base wind of 4-5 km/h was interrupted on 5 occasions by SW gusts approaching 30 km/h. Ridge winds were SW-SSW light to moderate in the morning becoming moderate to 1400 then moderate SE-E to 1800. It was cloudless to 1000 after which it rapidly clouded over to 90% cumulus that produced snow and flurries for the rest of the day. The west was clear to noon and the east to 1300 after which they became on average 50% and 20% draped with cloud respectively for the rest of the day. Once again despite unpromising circumstances there was a fairly strong movement of 40 raptors between 1112 and 1423 with 20 birds moving before noon. Most of the birds moved high overhead from Old Baldy to either Skogan Pass or Mount Lorette and only two were seen on the northern end of the Fisher Range. The flight comprised 5 Bald Eagles (2a, 1sa, 2j), 7 adult Sharp-shinned Hawks, 4 adult calurus Red-tailed Hawks (3 light, 1 dark), 1 Rough-legged Hawk and 23 Golden Eagles (12a, 3sa, 8j) which is the highest count for the species since April 12. 12 hours (518.57) BAEA 5 (182), SSHA 7 (32), RTHA 4 (34), RLHA 1 (33), GOEA 23 (2953) TOTAL 40 (3290)
