Thanks 
In response to Bob Lane and all others who have commented...

Thanks for this perhaps unique information about checklists, Bob, but the fact remains that this species is not considered to be 'countable', for official listing purposes here in Ohio, at this time. And part of this unique situation is that TRSW is a very 'long-lived' species. Some of the originally-released birds may continue to live for 25 years or more, and will therefore continue to be a part of the criteria for the 'established population' formula. This means that approximately 8 years may remain before these originally-released 'stock' birds will no longer be a part of this formula, and before this species will even be considered, by the OBRC, to be an 'established' population here in Ohio, assuming their continued increase in numbers and expansion within the state. I have been asked when I think they will become a 'countable' Ohio species, and my response is, 'When they are removed from the Ohio Review List, by our Ohio Bird
 Records Committee'; the truly governing organization. I don't know of any reputable Ohio 'birder/lister' who includes/reports Trumpeter Swan on their 'Ohio year list', or on their 'Ohio life list', to the ABA. Yes, this species is now 'countable' In Michigan, but they were released at the Seney, MI NWR many, many years before they were first released here in Ohio.
