(MD) (Montgomery Parks) Come to the Discovery Center and learn about our winged visitors at our bird feeding stations. Then we’ll take a short hike to our bird blind to see which waterfowl are on the lake and make a treat for you to take home for your backyard birds. Binoculars and guidebooks are supplied, but you can also bring your own. Register only those making bird treats. We’ll be using nuts and peanut products.
