# List of birds of Wyoming

This list of birds of Wyoming includes species documented in the U.S. state of Wyoming by the Wyoming Game and Fish Department (WGFD) as of May 2021 with some additions from Avibase. The list contains 452 species. Of them, 118 are classed as accidental, and seven species have been introduced to North America. An additional accidental species has been added from another source.
This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 62nd 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.
Unless otherwise noted, all species listed below are considered to occur regularly in Wyoming as permanent residents, summer or winter visitors, or migrants. These tags are used to annotate some species:
* (A) Accidental - "species with accidental, unpredictable, occurrence" per WGFD
* (I) Introduced - a species established in North America as a result of human action
