Records of bird sightings have been kept in Yellowstone since its establishment in 1872. These records document nearly 300 species of birds to date, including raptors, songbirds, shorebirds, and waterfowl. Approximately 150 species nest in the park. The variation in elevation and broad array of habitat types found within Yellowstone contribute to the relatively high diversity. Many of the birds are migratory species. There are currently no federally listed bird species in Yellowstone National Park.
The Yellowstone National Park bird program monitors a small portion of its breeding bird species to gather information like reproduction, abundance, and habitat use. Data is collected on multiple species from a wide variety of taxonomic groups, and has been maintained for 25 or more years for several species. Long-term monitoring efforts help inform park staff of potential shifts in ecosystem function, e.g., climate change effects, for Yellowstone’s bird community and may guide future conservation of the park’s birds and their habitats.
