After fledging the young peregrine falcons continue to work at strengthening their flight muscles.  They are frequently seen near the natal site flapping their wings and preparing for increasingly longer flights around the local area.  This young fledgling was seen with two other siblings on the corner of a rooftop of an abandoned building in the late day sun!  Notice the leg bands, black over green, 85/BS.
