Pueblo, Lamar, La Junta

Birding the Arkansas Valley

Southeastern Colorado stretches across expansive grasslands broken by reservoirs, cottonwood corridors, and quiet towns that double as migrant stopovers. The Arkansas River anchors the landscape, providing water and woodlands in an otherwise open prairie. Reservoirs host tens of thousands of waterfowl and shorebirds, while prairies support grouse, sparrows, and raptors. Spring and fall concentrate migrants in groves and shelterbelts, summer brings nesting herons, grebes, and prairie breeders, and winter is marked by cranes, geese, and open-water gatherings. What makes this region stand out is its sense of solitude paired with some of the state’s most abundant bird spectacles.
