March 9 (Valley View site) No observation possible. It snowed all morning (3 cm fresh) and I arrived at the site at 1330 when it appeared that the clouds were lifting which they did partially, but descended again after 1500 and I finally gave up on the day at 1710 when the temperature was -4C, it was snowing again and all ridges were obscured. Ground winds were light W-SW and ridge winds were mainly E. A flock of 30 Bohemian Waxwings flying high to the N at 1610 were the first for the season and bird species #30.

Mount Lorette [Day 9] (Jim Davis) It was a much better day at Mount Lorette where there was 5 cm of fresh snow on the ground, the temperature reached 2C in mid afternoon from a low of -10C, and ground winds were calm to light to 1400 after which they were N between 10 and 20 km/h before becoming calm again after 1700. Ridge winds were moderate NW-SW and cloud cover was 100% altostratus and cumulus to 1500 after which they cleared to 50% cover, and ridges were periodically obscured in part. A total of 33 migrant raptors moved between 0852 and 1700 with about 1 bird per hour to mid afternoon after which birds migrated quite steadily, with the flight comprising 2 Bald Eagles (1a,1sa), 2 adult Northern Goshawks and 26 Golden Eagles (19a,1j,6u). 11 hours (98.75) BAEA 2 (21), NOGO 2 (9), GOEA 26 (118) TOTAL 33 (158)
