List of birds of Colorado (original) (raw)

In the U.S. state of Colorado 519 species of birds have been documented as of September 2022 according to the Colorado Bird Records Committee (CBRC) of Colorado Field Ornithologists. 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.
