I was a bit concerned about Rory's analysis. My impression is that there
is a far higher contribution from Western Australia in this Atlas,
particularly the Kimberley. This would significantly bias the rankings of
some species. I assume that Rory has somehow standardised the data to
adjust for different reporting for each state? The comments by David
Geering about the different methodology give another reason why rankings
could be different.
Black-shouldered Kites are certainly not in trouble in the south west.
About 2 weeks ago, I went down to the Fitzgerald River in the south of WA
and I saw more BSKs than ever, which was particularly interesting as raptor
numbers are usually low in the south west in winter. And yes I atlassed
them as incidentals. My GPS is hooked into power from the car adaptor, so
I just record a waypoint each time I pass a raptor or something else of
interest. I similarly atlassed a couple of Richard's Pipits, which I also
consider to be more of a spring / summer species in the south west, but
this impression may be wrong.
