Identifying 'grey' geese

A tip for separating greylags from other grey geese in flight. All grey geese have uniform dark underwings apart from greylags, which have dark flight feathers that contrast very obviously with the much paler underwing coverts; or in other words if the grey goose flying overhead has a two-tone underwing it's a greylag, if not then its one of the others.
