Nah, There were probably 3 generations in the mob of Arabian
Shearwaters that were seen, so that would make them a valid tick under
the 3 generation rule.

I wonder whether everyone will wait for three self-sustaining
generations of Arabian Shearwaters in Australian Territory before
ticking them?? :)

Hi all,
If you want to count introduced species (which in my personal
opinion doesn't
really make sense), shouldn't you at least apply the "three
generation rule" (=
3
proven self-sustaining generations)? For long-lived birds like
Ostrich, this
means approximately 30-48 years of proven self-sustaining
population. Thus, the
NSW Ostriches need another 10-28 years to become "tickable".
