Birds on Wisconsin's Natural Heritage Working List – last revised May 2016. Life history, where they are found in the state, photos and management information is available for many of these species. Please consider sharing your observations [exit DNR] with the Wisconsin Natural Heritage Inventory
Many bird avoidance dates have changed, we are in the process of making these consistent across all documents, but for the most recent dates please go to the bird calendar. The bird calendar contains required (Avoidance Period) and recommended (Conservation Period) dates for avoiding impacts to rare Wisconsin birds when planning management or development activities.
