Wisser-Saworski Nature Preserve Boyne Falls Join local birder, Mary Trout, for a hike at the Wisser-Saworski Preserve near Boyne Falls. We will check the pool for frogs and turtles and the woods for nesting birds. Perhaps the Kestrel Box has attracted a pair of Kestrels. Loaner binoculars will be available, but bring your own if you have them. Please contact ltc@landtrust.org or 231-347-0991.
