I would for one would not trust that info at all. It very well may be a transplant but why one should ask.
I suspect more so, because of the price a hunt like that can bring.
I would only trust taking a bird from the line drawn bewteen Orlando to Tampa to be a honest true Osceola.

True Osceolas are found in South Florida in the Florida Everglades , specially the west coast By Naples Ft. Myers.
The Picayu Management area Holds A lot Of Osceolas with little pressure hunting.
