May 13 [Day 80] (Piitaistakis Ridge site) It was another beautiful day with a temperature high of 12C helping to make a few small holes in the snow pack on the ridge. Winds were mainly W gusting to 30-35 km/h after 1630, but before then they were mainly light and even calm for extended periods. Cloud cover started at 10% cirrus and gradually thickened with cumulus developing, reaching 70-80% after 1400 and giving excellent observing backdrops. Despite the seemingly ideal migration and observing conditions only 2 migrant raptors were recorded: an unaged Sharp-shinned Hawk at 1330 and a subadult Golden Eagle at 1736, and resident raptors and even ravens were also hard to find. The first Red-disked Alpine butterfly of the season looked a little incongruous flying over an unbroken expanse of snow. I have decided to return to the Valley View site for a couple of days to give the snow a chance to melt a little more, and to assess whether the raptor migration might, in fact, be almost over for the season. 11.75 hours (914.9) SSHA 1 (68), GOEA 1 (2164) TOTAL 2 (2960)
