The Rocky Mountains stretch from New Mexico to Montana, spanning enormous elevation ranges that stack different bird communities at different altitudes. Alpine tundra, spruce-fir forest, aspen groves, ponderosa pine, and sagebrush steppe each hold their own species.

Top Birding Spots
| Location | State | Highlight |
|---|
| Rocky Mountain National Park | Colorado | Alpine to montane, 280+ species |
| Yellowstone National Park | Wyoming | 300+ species, diverse habitats |
| Glacier National Park | Montana | Alpine to valley, boreal species |
