The Great Horned and Barred Owls are nesting 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, March 2 at 7 pm as we learn about their calls and habits and take a moonlit hike in the woods while practicing your owl calls. We recommend snowshoes or skis if the snow is deep. Meet at the Grass River Center and then we’ll take a night hike to listen and look for owl activity. More information at grassriver.org. Grass River Natural Area is located at 6500 Alden Highway, Bellaire MI.
