Illinois Ornithological Society Listers Corner
Over the years the IOS List Compilers have collected a number of submitted lists that we've found
very interesting to peruse. It seems a shame to keep them filed away in an archive, so we have
designed this web page with the intent of sharing them with others who also enjoy seeing this data.
We've added a section for Historical Lists, starting with the 1928-1943 compilation of the Lincoln
Park lists of William Dreuth. We look forward to adding more and we welcome your suggestions!
The downloadable lists are one-page pdfs that will allow for easy comparisons. All lists are restricted
to the 444 species currently accepted by the Illinois Ornithological Records Committee (IORC).
Big Year lists prior to 2018 may include Thayer's Gull.
