April 15 [Day 54] The day started with a light snow flurry, then the clouds cleared to 30% cumulus with sunshine. As yesterday, it didn’t last with snow flurries and showers persisting to 1710 when heavy snow developed depositing 2 cm by 1805, after which it cleared again. The temperature started at 0C, rose to 6.5C at 1500 and was -1C at 1900, and the upper winds were moderate WNW all day, although the ground winds varied considerably as squalls developed. A rapid rise in barometric pressure at the end of the day gives hope of better things tomorrow. There was raptor movement involving 7 species in the clear periods, with the first bird at 0828 an unidentified large falcon presenting a perfect silhouette against the eastern light and the last migrant, an adult Bald Eagle, moving between flurries at 1534. No birds moved after 1805 when things finally cleared up. The only passerine migrants were 204 Grey-crowned Rosy-Finches in 5 flocks, and a female Purple Finch at the site was the first for the year. 12.25 hours (606.7) BAEA 1 (399), NOHA 1 (9), NOGO 3 (91), RTHA 4 (130), RLHA 1 (15), GOEA 3 (2617), UF 1 (1) TOTAL 14 (3312)
The South Livingstone Raptor Count for the spring migration of 2008 has now begun. First official day of counting began on 20th February 2008. Follow the daily movement of raptors on this blog updated daily by Peter Sherrington.
