Bird day celebrates the beauty, song, and flight of birds. Olson Park is great place to bird watch, from migrant waterfowl in the wetland to songbirds in the meadow. Help us improve the habitat for these native birds by removing invasive shrubs. Meet us at the park entrance on Dhu Varren Road, just east of Pontiac Trail. Please dress in layers and wear shoes suitable for snow or wet ground. All participants must complete a release form, and all minors should be accompanied by a guardian. Tools, snacks, and know-how provided.
