The Quaker Pond Trail at Mendon Ponds Park is a 2.7-mile loop that circles a large marshy area and pond.  We may pick up lingering migrants, but we’ll be especially on the alert for local nesting birds setting up territories.  Woodpeckers are practically a given, as are blackbirds, finches and sparrows.  We may be able to coax a chickadee or titmouse to steal seeds from our hands.
