Content preview: I am an eBird reviewer for my region in British Columbia,
Canada. I don't know how your regions are defined in Australia, but here,
they are all relatively small geographically. Each region has its own
reviewer,
and each reviewer can change and adjust the filters as they apply to their
own specific region. The filters are designed to filter out unexpected
species,
out of season occurrences, and unusually large numbers. Reviewers regularly
see all the records that have been filtered for one reason or another. At
this point they are NOT part of the database; they are flagged as INVALID.
They remain that way until the reviewer has had time to evaluate any field
notes or photos that might have been submitted with the record, or, contact
the observer for those details. The reviewer must then decide, based on the
evidence provided, whether or not to deem the record VALID or leave it as
INVALID. I believe that if the reviewers do a good job, and the filters are
set appropriately, no obviously erroneous data will get through. That's
a big IF, though! It means that first the country has to be divided into
small
enough regions to be properly managed, and second, there needs to be enough
people willing to put their hand up to act as a reviewer. I know that when
I took on this region, there were already filters in place - presumably put
in on a much broader scale than appropriate. I have had to make adjustments
to many of my filters, and I continue to 'tinker' with them on an ongoing
basis. If there is a weakness to eBird, it is perhaps not in the system
itself,
but rather in the shortage of people willing to take on a region and then
to give it the time required to make it effective.Gary DavidsoneBird
