Colorado's dramatic elevation range from plains to 14,000-foot peaks creates diverse birding across life zones. During fall, bird activity is shaped by post-breeding migration and refueling along the Central Flyway.
Where to look
Explore forest, desert, wetland, urban habitat, including Rocky Mountain National Park and Barr Lake State Park.
Observation timing
Check migration corridors after favorable overnight winds and revisit fruiting shrubs throughout the morning.
