Title: Mixed marriage - White Wagtail

These 3 White Wagtails have been together on Po Toi since the middle of September. It seems like they are an adult leucopsis, adult baicalensis (as previously identified on this website) and a first winter bird.

If this is correct, and the first winter bird is the result of a mixed marriage, what will the juvenile bird become? One or other of the adult subspecies, or a mixture of the two?
