Hi Hector and Terry,
We should also keep in mind that leg-bands can also prove a wild origin and are worth reading. Although I don't have the exact details with me, a Scottish banded Barnacle Goose was shot by a hunter in Ontario in Nov/Dec 2005, thus becoming the first foreign banded wild Barnacle Goose to be recorded in North America. Just my opinion, but I think many of the New England Barnacle Geese occurring with other 'wild' geese will be good candidates for true vagrants.

interesting to this amateur.
As someone having seen the Barnacle Goose, I second Hector's
observations insofar as feather
wear and banding are concerned. Ditto on association with (obviously)
and exhibition of 'wild bird' behaviors.
