Tawny frogmouths fledging

Most of the tawny frogmouths have fledged young now or nearly so. The male below has two chicks which have been out of the nest for about two weeks. Although there are still several other pairs which have failed to breed successfully this year and others which are on second clutches of eggs or broods of young, after losing their first to predators - goshawks or possums?

This male's partner was one of the two females shown below. They were sitting together in the next tree from the male. Both birds have very similar plumage - these birds have diagnostic individual characteristics in their plumage. They have the same redness of their coverts especially. Why would the mother of the chicks allow a second female to approach them, let alone sit right next to herself? The second bird is probably related to her. Possibly a daughter from a previous year?
