Traffic stopped for the front of the parade on Charles Street at Mt. Vernon. The annual Duckling Day parade, sponsored by the Friends of the Public Garden (cq), is held on Mother's Day, on Sunday, May 13, 2012. Led by the Harvard University Band, children and parents walk from the Boston Common through Beacon Hill and end in the Public Garden. The parade is based on Robert McCloskey's children's story "Make Way for Ducklings."
