Today started off as a dark morning with winds from NE at just 10 MPH, light snow, visibility about 1/2 mile and temps around freezing.  Made a pass by the ballfields in Lawrence next to the Essex Correctional facility and spotted an adult Bald Eagle.  It was perched in a large tree just east of the water treatment plant.  Nice views over the Merrimack River from the elevated ballfields.  No other Eagle in sight and no clear sign that eagle had leg bands.
