John, again referring to HBW Vol 5, there was some talk of the New Guinea
population, Tyto novaehollandiae calabyi, being lumped into a megasubspecies
but differences appeared insuffiecient to warrant such a move. Consequently
it remains a race of our own Masked Owl (albeit referred to as the
Australian Masked Owl in HBW).
Tyto novaehollandiae forms a superspecies with T. aurantia, T. manusi, T.
sororcula, T. nigrobrunnea and T. inexspectata. Some consider T. sororcula
and T. manusi as conspecific with our Masked Owl.
