This is a list of bird species recorded in Baxter State Park, which is in the U.S. state of Maine. As of June 2004, 178 species had been reported by the Park. This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 63rd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.
