In reference to Tim Dolby's reference to not submitting the Pilbara
Elegant Parrot records to the Atlas.
I contributed 1000s of surveys to the Atlas. And I do feel guilty
that I haven't contributed as heavily to the Ongoing Atlas. Generally
I do it for the more out of the way areas that I might visit.
For me, the strength of the Atlas will be for monitoring changes in
the more common birds, and especially for changes at specific sites.
I don't see the Atlas as having much value for recording rarities, or
for birds outside their normal range. They need to be monitored and
protected within their normal range.
One weakness of the Atlas is that it requires a fairly specific
definition of the location. This meant that when I did Atlas, that I
completed a lot of incidental surveys. e.g. when heading east from
Geraldton I put in incidental surveys for my first sighting of birds
like Pied Butcherbird, Spiny-cheeked Honeyeater, etc. I also filled
in a lot of incidental surveys for raptors. Despite this, I used to
estimate that maybe only 80% of the species that I saw that day would
appear on the surveys, because I was moving around a lot. Even when
I was based in Broome (or Anna Plains Station) for an extended period
for things like the wader banding expeditions, I would find that
maybe only 60 to 70% of the species ended up on the survey forms. For
this reason, I would fill in a WA Database Card for the area so that
all the species were recorded, but on a far less specific location.
The WA Database accepts cards for shires, or National Parks, or
stations, or islands, or lakes, etc.
The other weakness of the Atlas is the time it takes to complete the
surveys. By the time that I have recorded my sightings on my
computer, and everything else, I don't have the time to then fill in
Atlas forms as well. e.g. when I am on tour with a group of people.
You are birding from dawn to dusk and then having dinner and doing a
bird call, etc. I can (and do) complete WA Database cards for areas
like Dryandra SF, Stirling Range NP, Albany Shire, etc as these take
little time. I also don't have time during the day to take GPS
readings for survey sites. It is simply not feasible for people like
George Swann in the Kimberley to Atlas. There are not enough hours in the day.
Don't get me wrong. The Atlas is a fantastic resource, and I applaud
everyone who has or still are contributing data. But it does have
limitations. But for me, the Atlas data is far more valuable for
repeatedly surveying a specific site, rather than for recording major
rarities or a bird out of its normal range. The fact that Elegant
Parrots occur in the Pilbara in winter is documented in books like
the two volume reference published by the WA Museum, and by papers
like that by Rob Davis. Having it in the Atlas does not contribute
very much extra.
