The shack lets me know when the wind rises to a 4 on the Beaufort scale by doing a shimmy. Kudos to Bill D for storing, maintaining and hauling the shack to the site.
Today was almost balmy: mild wind and staying near 32 and a clear sky. First bird of the day was a male Merlin. The Merlin and Peregrine were both first for the season. April Count so far,
