This is all very confusing, which makes it that much more fun. But I am gathering that the main contention is related to the checklist rule that does open the door to the argument that 3 generations may not be enough to establish a viable population. That would be the only hinge able argument, but alas it is a viable argument, although I still disagree. I will do some more research , which is dangerous.

If you look in the most recent "Birds Of Ohio Checklist" by the Ohio Division Of Wildlife (March 2012), and "The Ohio Records Committee Annotated Checklist Of Birds Of Ohio" (October 2008), it appears that Trumpeter Swan is the only bird specie listed in these two publications, other than extirpated or extinct species, that is not countable in Ohio.
