The following 435 species constitute the official list of Montana’s birds as of 6 February 2019. Since fall 1991, all records of rare species (i.e., documented 20 or fewer times in the state) were evaluated by the Montana Bird Records Committee (MBRC). Taxonomy and nomenclature follow the 7th edition of the American Ornithologists’ Union (now American Ornithological Society) Check-list of North American Birds and supplements to the Check-list published in The Auk through July 2018. Species with the label "R" are on the Review List and require a written report accepted by the MBRC before the record can be added to the Montana Bird Distribution database, which is maintained by the Montana Natural Heritage Program.
