I only came across this very comprehensive new Web Page only
I would be pleased to receive via Birding Aus readers comments
re accuracy and completeness.
"You will find an individual page for every country in the world larger
than 20,000 km2 .
For Russia, India, Indonesia, Argentina, Chile, Mexico, USA and Canada,
we list checklists for most states/provinces/departments usually leaving out very small areas"
It is hosted by "World Institute for Conservation and
Environment - WICE " who now have some involvement with Birding Australia's
Atlas Map Viewer.
and work your through the links and find
