List of birds of Yellowstone National Park facts for kids

Bald eagle

This is a comprehensive listing of the bird species recorded in Yellowstone National Park, which is mostly in the U.S. state of Wyoming and also extends into Idaho and Montana. This list is based on one published by the National Park Service (NPS) dated May 7, 2020 which contains 284 species.

This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 61st 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 the species on this list are considered to occur regularly in the park as permanent residents, summer or winter visitors, or migrants. The tags below are used to designate the abundance of some species. Because the NPS checklist notes abundance by season, the tag for the highest abundance of the year is used. The quoted definitions are those of the NPS.

• B Breeding: "Confirmed as breeding in Yellowstone" (155 species)
• b Unconfirmed breeding: "Suspected of breeding, but not confirmed by eggs or young" (four species)
• U Uncommon: "Found in small numbers and usually, but not always, found with some effort in appropriate habitat" (64 species)
• R Rare: "Occurs annually in very small numbers or in a very restricted habitat. Difficult to find" (76 species)
• O Occasional: "Occurs in some years, but not every year" (four species)
• V Vagrant: "accidental, vagrant, or species with few observations" for which documentation is requested (66 species)(see note)
• I Introduced - a species introduced to North America by humans (seven species)
