May 1 [Day 70] (Valley View site) The temperature rose to a high of 9C at 1400 and again at 1700 from a low of 0C and fell to 5C at 1900. Ground winds were variable gusting to 25 km/h between 1050 and 1215, but otherwise mainly light and ridge winds were light to moderate WNW becoming N after 1500. Cloud cover was initially 5-10% cumulus, which increased to 90-100% cumulus and stratocumulus after 1300 when flurries, showers and periods of hail and drizzle persisted for the rest of the day periodically partially obscuring the ridges. With pleasant weather and an Osprey moving north at 0946 it appeared that we might finally get a decent day’s raptor movement but only a further single Red-tailed Hawk migrated before 1400. A small movement of 6 Golden Eagles (1a,4sa,1j) occurred between 1410 and 1647 and an adult Bald Eagle soared high to the south with 3 Common Loons [bird species #66 for the season] at 1705 to complete the day’s count of 9 migrants. 12 hours (811.2) OSPR 1 (5), BAEA 1 (377), RTHA 1 (97), GOEA 6 (2103) TOTAL 9 (2806)
