IORC Update, 2 September 2022: Records Reviewed

By /

The Illinois Ornithological Records Committee (IORC) recently concluded evaluations of 10 records of the occurrence of rare birds in Illinois. IORC accepted six of these records and did not accept the other four.

The records involved are summarized below. For each record, we indicate the species or form, with number of individuals in parentheses if greater than one, followed by date or date range, location, and county. The record number is indicated in parentheses, followed by, for accepted records, names of the documenters. If multiple documenters are listed, those understood by IORC to have been the original finders of the bird(s) are listed first and separated from the others by a semicolon. IORC thanks all the documenters, for accepted and unaccepted records alike, for their submissions. All documentation is maintained in the IORC archives so that there is a permanent record of all these observations. Documentation, regardless of the Committee’s decision, is a valuable part of the record of bird life in Illinois.
