Seams to be a released pet as discussed in this observation from 2019:
https://www: inaturalist.org/observations/31801159
American Birding Association field trip led by Brian Rapoza, and with Holly Lovell and 20+ others.
My first visit to this site, when many species of released waterfowl were still present; all but the Egyptian Geese had died out within 10 years.
To other iNatters: please do not mark this record as "not wild" in the attributes. I admit that these birds were intentionally released but I'm not aware that any was pinioned (many were metal-banded).
@raymie researched the validity of "counting" escapees/releases -- which of course is greatly confused -- but it seems that an intentionally released bird is nonetheless countable by iNat standards. A few of these records are resubmissions because the original submission got shot down to "casual" based on a majority of "organism is wild" marked with an X.
Here's the discussion that @raymie found:
