G’day all
Many thanks to those who answered my request for info on the status of Boobooks in Australia. I opened a can of worms apparently. All good info and healthy debate!
It seems that there is more work to do to unravel the situation and there are clever people on the job. I will follow the IOC for now and look forward to new knowledge.
I just wish I saw these great little beasts more often.

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.
