The two birds in the photo are quite obviously Greylag..such large geese with pale underwing and extendive pale grey on the forewing could only be that species.
As to Graham's query, I think Twite answered it sufficiently. As WF Goose attain 1st winter plumage they begin to attain the paler bill tip and also the white 'shield' at the base of the bill.
