Canada Goose paired with White Domestic Goose

There was a strange pair of friends on Greenhill today.  I first saw them coming down the field together, little and large.  Unfortunately I didn't get a photo but their subsequent behaviour on the water confirmed they are pals.  Whether they are mating, is another question.  But it is unusual to see a small Canada goose keeping company with a large white domestic goose.  Can't wait to see what happens next.  Here are some pictures of the little Canada Goose and the large White Domestic Goose.
