Just ten minutes after watching the adult, noticed a subadult perched on the north side of the river just west of where the Spicket River empties into the Merrimack.  This is the regular perch location for the eagles and it is just across from the parking lot on the west side of the NX Stage Medical Inc. building.  Buried in the tree branches was this subadult.  It flopped around and changed perches before circling twice and then heading downriver.  The movement provided a nice moment for flight images!  Enjoy!
