April 21 [Day 62] (Valley View site) For the second straight day the temperature reached 20C at 1700 from a low of 1.5C, and at 1900 it was still 17.5C. Ground winds were E to variable and mainly light, and ridge winds were probably light E although cloudless skies throughout the day made assessment of the upper winds difficult. Yet again raptor movement was slow with only 13 birds moving between 1010 and 1819, although there was good variety with 9 species of migrant recorded including the season’s first Turkey Vulture, an adult bird at 1618 [species #60]. Other migrants were 1 Osprey, 2 Bald Eagles (1a,1sa), 1 adult male Northern Harrier, 1 adult Cooper’s Hawk, 1 adult Northern Goshawk, 1 adult dark morph calurus Red-tailed Hawk, 2 Rough-legged Hawks (1 light, 1 dark) and 3 Golden Eagles (1sa,2j). There was also a good variety of other birds giving a season high count of 35 species (but only 96 individuals) including the season’s first Vaux’s Swift that flew low to the south almost overhead at 1634 for the first April record at the site and the 61st bird species of the season. 12.25 (721.3) TUVU 1 (1), OSPR 1 (3), BAEA 2 (372), NOHA 1 (10), COHA 1 (7), NOGO 1 (80), RTHA 1 (83), RLHA 2 (38), GOEA 3 (2071) TOTAL 13 (2730)
