eBird or Birdata

[Dave Torr <>]

An issue I have with Birdata is that it only covers Australia -if one birds internationally at all it makes sense only to use eBird of course!

Dear Jack,

If there really is a robust mechanism to transfer all 2ha20 surveys from
eBird to Birdata, then why not use eBird? Seems to be the best of both
worlds.

That being said, I think there is also a scientific case for eBird: more
poeple use it, so the statistical value of the data goes up. And
speaking as a mathematician with significant statistical training (but
I'm not an orithologist), I would say that there is still quite a lot of
statistical value in eBird data as one could write down all sorts of
estimators taking into account the human psychology and bias that is
introduced into birdwatching. Also, while methodologies aren't as
strongly suggested on eBird, they also have a very convenient way for
ornithologists to download data, which means your data will be available
to more scientists.

Of course, if the 2ha20 data that is uploaded to eBird is NOT being
transfered to Birdata, then there is a much strong suggestion to use
Birdata. I am actually curious how Birdata does this, considering all
sorts of lists formats on eBird are used. How does Birdata detect the
lists it needs?
