Thanks to Jim Stasz, Walter Ellison and Hans Holbrook for directions to Great 
Oak Pond.   Clive Harris made a valuable point concerning hybrids of Barnacle 
and Richardson's Geese, regardless of the sub-species.   Richardson's now 
breed in Greenland, so a zone of overlap with Barnacle is a real possibility.   
If one could establish that a pair-bonded Barnacle/Richardson's Goose pair was 
present, one could make the case for natural origin.   I'm saying make the 
case, not prove, but all these BAGOs can't be escapes.
