Appears to be a domestic Cayuga duck crossed with perhaps an Embden or
some other large white domestic duck species.

Subject: [Tweeters] Unidentified goose

The following two images are of a goose feeding with a flock of Canada
Geese near the Issaquah Red Barn on the morning of 29 Jan 2010.

I cannot identify it and it does not appear to be domestic.

They can be enlarged to full screen by "hovering" your cursor over the
top right hand corner of the main picture and selecting the desired size
