Most readers will be familiar with the Checklist of the Birds of Ohio, from the Ohio Bird Records Committee. This authoritative reference is around in the thousands in hard copy, and is also on the OOS web site as a pdf file through a link at http://www.ohiobirds.org/publications/checklist/checklists.php . Because it is impossible to update this list several times yearly, we are now posting an Offical Ohio Bird Checklist that should be current within days of developments. The OBRC Checklist treats 412; this one, at http://www.ohiobirds.org/publications/checklist/official.php , has 419. This is a simple but complete version, in current taxonomic order, organized by family, with current English and scientific names for all 419. It should be useful for folks developing their own checklists, for life-list recording, etc., as well as for keeping up to date. The official checklist is most likely to change as new species are well documented and accepted by the records committee, and even more often as the AOU revises and refines the North American list. You will see, for example some changes in the taxonomic order (the cuckoos' order has been reversed, jaegers have moved, etc.) as well as a lot of new (actually most are well over a hundred years old, but newly applied) scientific names, all changes new this past July. We will keep up with these developments, and update this on-line list as needed. Please advise if you find any errors.
