The reason is pretty straightforward. The total known population of Night Parrot right now is less that 20 across the nation at probably four sites .  You don’t muck around with a bird when it’s numbers are that precarious. It would have been quite easy for the WA netters to ascertain a population estimate by simply surveying the area and listening at dusk.

Hello Greg,


Sure but isn’t that circular reasoning. The act of trying to capture them is surely the part of the process to ascertain how many birds were there. With such a cryptic species WA Night Parrot example, until recently thought possibly to be extinct, how can you know how many are there otherwise? Although the purpose of trying to band some of them is independent of how many are there. So what if there were 2 or 50, I don’t see how that makes any difference to the project proposal of banding some of them, as a start point to a study.

Thanks for your input Stephen.


I have friends who have been members and even chaired animal ethics committees. I know there are good people out there doing good work.


However , if we look at the WA Night Parrot example , how could that netting have been approved when no attempt was made to ascertain how many birds were there ? By some accounts there was just the single pair, and they are now gone. And what was the outcome when the ethics committee was informed of this unfortunate result?


In the case of the Red Goshawk, it is difficult to make a more firm assessment when both the Queensland Environment Department and Rio Tinto refuse to answer questions.
