The Great Horned and Barred Owls are beginning to nest at Grass River Natural Area. Do you know which owl you’re hearing when they “hoot” at night? Join us at Grass River Natural Area on Friday, January 25 at 7 pm to learn about their calls and habits and take a moonlit hike in the woods. This 1.5 hour program is $5 per person. We recommend snowshoes or skis if the snow is deep. For more information or to register visit grassriver.org. The entrance to Grass River Natural Area is located at 6500 Alden Highway, Bellaire MI.
