Swifts or Martins?

Alan Hopkins

There are birds flying around the lighthouse on the Farallons at the moment. I can't tell if they are Black Swifts or Purple Martins. The best view is from the East Landing It can be very frustrating because people seem to like to point the camera at fog. Farallon Islands Live Webcam
