G'day John,
A possible mechanism could be that the Tasmanian, Norfolk and NZ birds
represent an older ancestral population of Boobooks which was originally
Australian wide. The mainland birds could represent a much more recently
evolved form that hasn't completely replaced the older types, or may never
replace these remnant older types which may be better adapted to colder
wetter environments.
Cheers Jeff.

Hi All,
the complexities of genetic studies, phylogeny, vocalisation, and so on!!
I'm not at all phased by the thought the Tasmanian Taxon might be separate
to the mainland Boobook - though if some DO cross the Straight, that makes
things interesting!
But for the life of me, I cannot envisage a speciation mechanism that would
allow for the Tasmanian Taxon to be separated from the mainland Boobook, but
still to be part of the same species as the NZ and Norfolk Island Morpork???
Cheers,
John Tongue
Ulverstone, Tas.
