Avibase - Bird Checklists of the World

Maine

This checklist includes all bird species found in Maine , 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 Avibase taxonomic concepts (current). 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).

Bird Checklists of the World is part of Avibase and Bird links to the World, which are designed and maintained by Denis Lepage, and hosted by Birds Canada, which is a co-partner of Birdlife International.
