April 8 [Day 51] (Valley View site) At 0700 it was calm with steady wet snow falling but after 0800 SW winds developed becoming increasingly strong reaching gusts of 90 km/h at 1800. Depending on the temperature, rain, snow or flurries persisted until 1800 and cloud cover was 100% mainly stratus to 1600 after which it periodically thinned to 70-80% cumulus, stratocumulus and altocumulus and even provided some periods of sunshine. The temperature started at 1C and rose to 6C at 1000 after which it steadily fell dropping as low as -2C during snow storms that periodically swept down from the west. The only migrant raptor seen was a light morph Rough-legged Hawk at 1554, and even when the Livingstone Ridge was clear after 1600 snow to the south prevented any further movement. 11.25 hours (594.1) RLHA 1 (29) TOTAL 1 (2497)
Mount Lorette [Day 39] (Joel Duncan) Joel Started the day at the Hay Meadow site but snow and obscured ridges at 1100 had him moving to the Lusk Creek site where the ridges remained clear until snow moved in at 1300 at which point he terminated the count. The temperature at Hay Meadow ranged from -1C to 2C, and winds were strong SW to W all day. Not surprisingly no migrant raptors were seen but a male Brown-headed Cowbird at Hay Meadow was the earliest ever recorded at the site by 10 days. 5.5 hours (438.7) No migrant raptors (1245)
The Piitaistakis (South Livingstone Ridge)and Mt. Lorette Raptor Counts for the spring migration of 2010 are underway. Follow the daily movement of raptors in these field notes by Research Director Peter Sherrington and his citizen scientist colleagues.
