April 26 [Day 67] (Valley View site) (Dawn Hall to 1200) The temperature reached a high of 12C at 1600 from a low of -4C at 0700, and it was still 10.5C at 1900. Ground winds were mainly light and variable and ridge winds were light to moderate W for most of the day. It was cloudless with some light valley fog until 1000 after which a mixture of cumulus, cirrostratus and cirrus cloud gradually increased reaching 100% after 1400 thinning to 40-80% between 1600 and 1730. The clear conditions produced some raptor movement but it was very slow with 13 birds moving between 0947 and 1649, with 4 of the birds occurring after 1600. The flight comprised the season’s 3rd adult Turkey Vulture, 1 late subadult Bald Eagle, 3 Sharp-shinned Hawks (1a,2u), 1 juvenile Cooper’s Hawk, 1 unidentified small Accipiter, 1 juvenile light morph calurus Red-tailed Hawk and 5 Golden Eagles (1a,1sa,2j,1u). A white-crowned Sparrow was the 63rd species of the season. 12.5 hours (778.7) TUVU 1 (3), BAEA 1 (374), SSHA 3 (41), COHA 1 (12), UA 1 (6), RTHA 1 (96), GOEA 5 (2090) TOTAL 13 (2784)
