@King of Komodo Dragons - do you mean the Parrots in North America thread? The only comment like that was by @Great Argus themselves saying "Was told it's the last of it's kind in NA I see."
@Chlidonias Dallas's bird is the only one known to be left in a public facility, far as I have heard from a few different sources. It is quite possible there may be a few in the private sector, I have not heard any recent reports of this though.
