Milk River Natural Area, the only Important Bird Area in the United States, is studded with cliffs and eroded sandstone badlands that serve as important nesting and foraging habitat to the area's raptors, the populations of which have experienced rebounds since the 1970s when the insecticide DDT was outlawed.
Milk River Natural Area is a provincially designated protected area in the southeastern corner of the province of Alberta, Canada, approximately 160 km south of the city of Medicine Hat.
