Rare Birds Review List

Documentation Required

The following species always require documentation, reviewed by the seven member Records Committee, to archive the details of birds rare in Iowa.  This list is subject to change annually as we learn more about distribution and as records ebb and flow.  Check back often to see those changes.

These species, although meeting criteria to be regular in the state, should be documented when they are observed away from known locations:

  • Ferruginous Hawk - Hitchcock Hawkwatch in fall, Pottawattamie County
  • Black-billed Magpie - Broken Kettle Grassland, Plymouth County
  • Bewick's Wren - Argyle junkyard, Lee County
