Welcome
to the Maine bird checklist.
There have been 471 species in 236 genera in 65 families in 22 orders of non-domesticated birds observed in and over Maine, including the adjacent ocean. Taxonomy and nomenclature follow the American Ornithologists’s Society Check-list (65th supplement; July 2024)
Below is a working checklist
of birds that have been observed in and over Maine or on the adjacent ocean. For more information about a particular species, click on the link under the heading “common name”, and you will be taken to a page for the order that includes that species. Otherwise, to determine which order the bird that you are trying to identify belongs to, refer to the tabular key at the bottom of this page.
