In honor of World Migratory Bird Day, Clayton High School student members of the City's Sustainability Advisory Committee invite families to a morning of guided bird walks, educational exhibits, and youth crafts at Oak Knoll Park. Expert guides from the Missouri Bird River Conservatory and local research community will lead walks at multiple time slots throughout the morning. The event highlights this year's conservation theme — the threat of artificial light at night to migratory birds — and explores how local residents can make a difference. Free and open to the community.
