HI all, It does not seem to make sense, in a biogeographic sense that
Tasmanian and NZ Boobooks are the same species while mainland ones are another.
I can't think ofany other species pairs between Tas and NZ. Perhaps the birds
share some similar characteristics beacuse they inhabit wetter forests and more
southern forests than mainland birds. There is also the northern Atherton race,
lurida I think to consider as well. Would that be a seperate species too???
