A site interpreter at Pere Marquette State Park will be presenting informative programs about bald eagles this winter. Visitors will learn to distinguish between immature and mature bald eagles, what eagles eat, why they spend winter months in the area and much more. All programs will begin at the park's visitor center at 8:30 a.m. Reservations are required. There will be a short video presentation followed by an observational drive to view the wintering bald eagles. Please dress warmly and have a full tank of gas.
