Observers: Claude Radley, Janina Radley, Jim McCoy, Olga Klekner,
Rene Kielbasa
Visitors:
Thanks to all who helped spot birds that were in some cases well to the
north of the tower and quite high.
Weather:
Today the sky was almost cloudless, the temperature rising from a low of
5.2 to a high of 11.8. Initially there was a very slight breeze from the
NE, but by 10 am this had shifted to SE. Fortunately the wind remained
mild, so the migration was not pushed too far to the north.
Raptor Observations:
Migration was minimal until 10 am, by which time the sunny skies had
allowed for enough thermal generation to get a reasonable Red Tail movement
going despite the less-than-ideal winds. This continued steadily for three
hours, and then became a slow trickle.
Non-raptor Observations:
Several groups of Tundra Swans totalling 47 birds were seen flying over,
and several other flocks were heard passing nearby.
Predictions:
Another mild day with temperatures starting at 11 and rising to 13. Cloudy
with possible showers in the morning, cloudy with sunny periods in the
afternoon. Winds mild to moderate initially from the SW becoming W early.
