Checklists and Indexes
We have a printable checklist of the more common birds of Ohio in PDF form.
The Ohio Ornithological Society offers several checklists of Ohio birds. You may want to consider their Weekly Checklist, which limits the list to the birds likely to be seen on or near the date that you choose.
Bill Whan has created an index for Bruce Peterjohn's The Birds of Ohio; this index can be printed and pasted into the back of your copy.
