[Tweeters] Vaux's Happening

[Nelson Briefer]

Some interesting questions from Jim Betz. And I will build upon his
thinking. These swifts— are they being observed by Merlins or Peregrines?
How about Goshawks ? Are some raptors attacking the large quantity of
swifts? When is the ideal time for a hawk to attack a swift. I would think
when the swift is perched. cheers — Nelson Briefer — Anacortes.
