These discussions tend to generate a lot of digression and discourse about hardly related topics. For instance, there have been almost as many postings about the number of birders in UK versus Australia as there have actually about night parrot. I would like to find out more about this bird by sharing knowledge about it - after all, this is a very powerful forum for this purpose.

I have a couple of issues for consideration:

1. Why do we believe night parrot is actually nocturnal? I am going to pose a hypothesis for discussion, thus:

***Night parrots are considered nocturnal because, i) hardly anyone ever walks through their habitat during the day; and ii) because most sightings are made when the animals are 'on the move' (rather like roos) in the evening, travelling to and from watering holes like other similar-sized parrots e.g. Bourke's parrot. Night parrot is not nocturnal at all. This assumption derives entirely from sampling bias.

My next hypothesis:

***Night parrot is, like many other Australian birds, nomadic. However, even nomadic birds occur in some areas 'regularly' and can be seen with some reliability. If the first hypothesis is correct, we hypothesise that the Diamantina region is an area where night parrot occurs consistently and that a given level of effort (of unknown person-hours) would result in the bird being found regularly.

Please respond to the list, not to me. And try not to digress from the point - keep responses to the thread relevant to the thread, or else set up a new thread.
