Had an unexpected encounter with a likely 3rd year subadult Bald Eagle.  It was perched on a tree branch overhanging the Merrimack River in Methuen opposite the Lawrence Municipal Airport.  At first, it looked like possible Red-tailed Hawk through the thick tree branches….but after a closer second look and seeing the bill, then it was easy to make the eagle call.  The plumage points to a likely third year bird.  A nice unexpected treat while searching for adult eagles!
