Birding Eastern Montana

Eastern Montana stretches across a vast, windswept landscape of prairies, badlands, and sagebrush flats where the Yellowstone and Missouri Rivers trace broad, cottonwood lined valleys. The region’s open spaces and varied terrain make it a premier destination for prairie and riparian birding alike. Grasslands support longspurs, sparrows, and raptors, while wetlands and reservoirs draw flocks of ducks, ibis, and shorebirds. The badlands add rugged beauty and isolated habitats filled with cliff nesting species. Each season brings distinct rewards, with spring and fall migration through river corridors, summer breeding in the grasslands, and winter birding along frozen rivers and windswept plains. What makes Eastern Montana stand out is its remote authenticity, birding here is as much about vast horizons and solitude as it is about remarkable species diversity.
