My 1946 edition of 'What Bird is That? shows the 'Cave Owl' as a sub-species
of the Masked Owl with the trinomial Tyto novae-hollandiae troughtoni. "The
type, adult female, collected at Ooldea, East-West Line, South Australia by
Messrs Troughton and Wright on 16 October 1921".

Subject: 'Cave Dwelling' Masked Owl
I think it's listed as a separate species in "What Bird Is That?", with its
own picture, but I haven't got it here to check.

I think that it was seen as a separate 'form' in the early 20th century.
But it's genetic distinction is very doubtful. Yet, some non-scientific
websites (e.g. Wikipedia) describe it as an accepted subspecies (which it
isn't), which I've seen on both the Masked Owl and the Nullabor Plain
page; the latter says 'An elusive subspecies of the Australian masked owl
unique to the Nullarbor is known to roost in the many caves on the plain.'
With no reference of course! It's interesting how this rumour still seems
to persist at least in some places.
