November 20 [Day 86] (Valley View site) It was the most pleasant day for a while with the temperature rising to 9C between 1200 and 1530 from a low of 2C and was still 7C at 1700. The strong winds finally abated with ground winds WNW-SW only rising above 20 km/h after 1300 and peaking at 45 km/h at 1700, and ridge winds were mainly moderate W only becoming strong after 1500. Cloud cover was mainly altostratus, altocumulus and cirrus gradually increasing from 20% at 0710 to100% for most of the afternoon, which generally produced hazy sunshine and gave excellent observing conditions. A total of 58 raptors migrated between 0805 and 1620 which is the highest combined species count since November 9. The count of 46 Bald Eagles (37 adults, 2 subadults, 7 juveniles) was the highest so far this season and is the second highest ever at the site behind the 49 counted on November 17, 2006. All but one of the birds moved before 1448. The 10 Golden Eagles comprised 9 adults and 1 subadult, and the Prairie Falcon at 1024 was the first migrant of the species since October 1. Two adult Bald Eagles gliding high to the south together at 1121 had a brief altercation that resulted in one bird performing a complete 360 degree barrel-roll before they serenely continued their journey. 10.25 hours (983.46) BAEA 46 (499), RLHA 1 (69), GOEA 10 (4191), PRFA 1 (12) TOTAL 58 (6836)
