A few weeks ago I attempted to photograph the Greater White-fronted Goose 
but my camera's auto focus was malfunctioning.  Tonight I did locate one 
photo that can at least be used for ID purposes and put it on my site here:

(Note that this goose and the surrounding Canada Geese had just flown in 
from somewhere evidently quite muddy - this goose's bill color appears 
duller due to the dried mud.)

Walter and Nancy, thanks for the additional insight on the goose hybrid, 
it is sincerely appreciated!
