Well ... All I can add is to repeat that the AOU considers it to be a
legitimate species (see note below re the 7th edition checklist) and
considers it to be established at a few locales in North America (even if
the local state records committees don't !!!). The MOS (and most other
North American birding organizations) defer to the AOU on issues of
taxonomy and general North American status.
