April 16 [Day 52] (Valley View site) A cloudless sky allowed the starting temperature to fall to -5C, but it eventually rose to a high of 10.5C. The first traces of cumulus cloud appeared at 0900 and by 1100 cumulus cover was 80% after which it gradually dwindled becoming cloudless again after 1800. Both ground and ridge winds were mainly light all day, the ridge winds being E until 1330 and then W, but in each case the clouds were hardly moving. It was another slow day for raptor movement with the first migrant, a Rough-legged Hawk, not seen until 1131. Eight of the day’s 19 birds occurred between 1500 and 1600 but subsequently only 4 more birds were seen with the last, an adult Bald Eagle, moving north at 1810. At 1746 a flock of 6 high soaring adult California Gulls contained a single adult Herring Gull, the first to be seen on a spring count here, and at 1914 another flock of 20 California Gulls soared high above the Livingstone Ridge before moving off to the east. 12.33 hours (571.2) BAEA 5 (383), NOGO 1 (76), RTHA 4 (110), RLHA 1 (20), GOEA 6 (2496), MERL 2 (16) TOTAL 19 (3146)
