Avibase - Bird Checklists of the World
Bill Williams River National Wildlife Refuge
This checklist includes all bird species found in Bill Williams River National Wildlife Refuge , based on the best information available at this time. It is based on a wide variety of sources that I collated over many years. I am pleased to offer these checklists as a service to birdwatchers. If you find any error, please do not hesitate to .
The taxonomic order and nomenclature follows Howard and Moore 4th edition (incl. corrigenda vol.1-2). If you prefer to view the list based on a different authority, click on one of the list available below. Globally threatened species (status in red) were identified by Birdlife International in Birdlife Data Zone (species).
