IORC Update - 8 June 2017

The Illinois Ornithological Records Committee (IORC) recently concluded evaluation of 19 records of occurrence of rare birds in Illinois, accepting 14 and not accepting five. For each record, we indicate below the species or form, with number of individuals in parentheses if greater than one, followed by date or date range, location, and county. At the end, the record number is indicated in parentheses, followed by, for accepted records, names of the documenters. 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.
