The almost year old female Peregrine Falcon in juvenile plumage continues to be seen in Woburn.  This morning it was perched on a ledge in a rocky outcropping taking in the morning sun.  It called periodically, but in a very low tone.  The winds were light out of the west, with clear skies, bright sun, and temps in mid-thirties.  The immature peregrines have more brownish plumage than the blue-gray on adults.  In addition, the immature falcons have heavier breast streaks.
