April 4 [Day 47] (Valley View site) The temperature rose from a low of -3.5C to 5C at 1400 and was 2C at 1900, ground winds were mainly SW gusting to 35 km/h and ridge winds were WNW-NW strong to moderate, becoming moderate after 1700. Cloud cover ranged from 80 down to 30% mainly cumulus and very thin cirrostratus giving generally good to excellent observing conditions. A total of 36 raptors of only 3 species migrated between 1050 and 1757 with 27 of the birds moving between 1300 and 1700, the flight comprising 2 adult Northern Goshawks, 5 adult Red-tailed Hawks (3 light calurus, 2 dark harlani) and 29 Golden Eagles (16a,9sa,4j). Around 0830 5 species of woodpecker were present simultaneously near the site: a male American Three-toed Woodpecker was drumming on a snag to the south on which a pair of Downy Woodpeckers was also perched, a female Hairy Woodpecker was feeding on a tree to the east, and to the north a Pileated Woodpecker was calling while two male Northern [Red-shafted] Flickers were bickering in a grove of aspens. 12 hours (546.6) NOGO 2 (67), RTHA 5 (40) GOEA 29 (1959) TOTAL 36 (2459)
