As the sun was setting, made a late day visit to downtown Haverhill in search of the Peregrine Falcons.  After searching high and low, and with quite a bit of luck, was able to locate the unbanded female on a rooftop corner on the north side of the Merrimack River, just on the east side of Riverfront Park.  After a bit, it made a short flight to the rooftop to the west and joined the male who had been perching on the east side of that building….so BOTH!
