The WSO Review List indicates rare species that have occurred in Wisconsin but require documentation for acceptance into the state records. As of March 1, 2018, detailed eBird reports will suffice as appropriate Review List species documentation. To read more about this policy, please click here. For birders who do not wish to eBird, you can fill out the Rare Bird Documentation Form for these species, or any species not on the list that would represent a first state record. Completed forms are assessed by the WSO Records Committee.
