March 24 [Day 20] (George Halmazna) The temperature at 0650 was -12C and fell to a low of -15C at 0800 before climbing to a high of 0C at 1400. Ground winds were initially calm to light SSW in the morning becoming E then north in the afternoon occasionally gusting to 40 km/h, while ridge winds were variable and light all day. The early morning was cloudless but cloud rapidly developed reaching 100% stratus at 1100 which thereafter varied between 80 and 100%. The top half of the western ridges were covered in cloud all day, as was the top third of the eastern ridges for most of the day. Despite these apparently unpromising conditions the first Golden Eagle appeared at 1015 and the day's movement peaked between 1200 and 1300 with 167 raptors of which 151 were Golden Eagles, while the following hour yielded 115 raptors of which 112 were Golden Eagles. By the time the last migrant Golden Eagle had headed to the NW at 1743 a season high total of 452 birds had been tallied comprising 14 Bald Eagles (11a, 3j), 1 adult Northern Goshawk, and a season high count of 452 Golden Eagles (417a, 1sa, 19j). Most of the movement took place to the W of the site and birds moving above the E part of the valley moved to the NW directly over Skogan Pass meaning that only 2 birds were seen over Mount Lorette all day. Other birds recorded included 2 American Crows (the first of the season), 2 male Mountain Bluebirds and 1 male Red-winged Blackbird. 12.5 hours (218.58) BAEA 14 (75), NOGO 1 (5), GOEA 437 (1554) TOTAL 452 (1655)
