Made a very enjoyable visit to observe the Peregrine Falcons in Woburn under partly sunny skies and broken clouds, winds from NW at 12 MPH and gusts over 20MPH, temp around 40F.  Both male and female seen perched and in flight around the local quarry area.  At one point, the female flew off and landed on a rocky outcropping about 165 yards SW of the nest ledge on the west wall of the quarry.
