Google gave me a lot of information, including a "List of Migratory Species Under the Environment Protection and Biodiversity Conservation Act 1999" which clearly lists Ninox novaeseelandiae undulata, as a migrant. Anyone care to comment, I thought (assumed) Ninox to be rather territorial and sedentary,
Hi Graham
If you have a good look at the list of migratory and marine-overfly
species listed under schedules of the EPBC Act, you'll see that the
birds there are those listed under the CAMBA and JAMBA treaties
(China/Japan Migratory Bird Agreements). You'll also see that there are
quite a number of species there which just don't make much sense - ie.
they're not migrants - take the endangered SE Aus Red-tailed
Black-Cockie for example - why is it on this schedule!!!???
Having said that though, _Ninox (novaesselandiae) undulata_ like a
number of other species listed, lives on a small oceanic island and
presumably established there as a result of some long lost ancestors
making the sea crossing. Perhaps that's why some of these oddities are
so listed (rather than just as one of the threatened categories). It's
my best guess ...
Cheers, Lawrie
