Species in ALL CAPS can be classified into three categories in the state of Iowa: 1) UNRECORDED, ACCIDENTAL or Casual; 2) A RARE but regular species; or 3) record early or late date or unusual for time of year. Any species with three asterisks (***species***) would represent a first record for Iowa (UNRECORDED) and should be observed and documented very carefully. Species with two asterisks (**species**) are species that are either ACCIDENTAL, CASUAL, or a rare regular species, and should also be documented. Species with one asterisk (*species) should have some details of the observation provided.
Please note this is an UNOFFICIAL compilation of rare bird sightings from both eBird and the IOU listserve. Data for field reports and early/late dates should not be taken from this weekly report.
