The WSO Records Committee validates and maintains records of rare bird sightings in Wisconsin. It receives reports of rare birds submitted via WSO documentation forms and votes to accept or not accept records based on the quality of evidence presented by each observer.
June 2012 Update: The Records Committee recently revised its list of species requiring review and modified the forms for documenting rare birds. After sighting a rare bird, birders should consult the Review List below and fill out the online Rare Bird Documentation Form if required. Seasonally rare birds, as indicated by the Arrival and Departure dates, should also be documented (using the Rare Bird Documentation Form below) if record early or late.
