Made a pass by one of the bridges in Haverhill this morning in search of the newly discovered Peregrine Falcon nest with possibly 4 chicks.  This nest has been relocated from the nest location of 2015.  To my surprise the female was perched on a rebar perch over the Merrimack River and seen at very close range.  As she was guarding her growing chicks, she seemed very reluctant to move her position, and that meant to keep back at a very safe distance!
