Benton Lake National Wildlife Refuge
Great Falls
On the windswept prairie east of the Rocky Mountain Front, Benton Lake National Wildlife Refuge is a landscape of continental scale — 12,383 acres of marsh, prairie, and shelterbelt habitat that has earned dual recognition as a Globally Important Bird Area and Western Hemisphere Shorebird Reserve Network site. The U.S. Fish & Wildlife Service explicitly names Benton Lake as key habitat for the Calliope Hummingbird, the smallest long-distance avian migrant in the world. Though the refuge is primarily famous for its grassland and wetland bird diversity, the shelterbelt plantings and riparian shrub zones along the auto tour route provide hummingbird habitat from May through August. This is prairie birding at its most immersive — vast, wild, and scientifically significant.
