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".

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.
