Randall Creek is one of the South Dakota state parks that offers the opportunity for visitors to see the majestic bald eagle. The eagle roost area in the park is a designated National Natural Landmark. In South Dakota, many bald eagles spend their winters below the Missouri River dams where they are able to catch fish and prey on waterfowl attracted to the open water. They typically perch within 50 feet of the riverbank in tall Cottonwood trees. The birds usually feed in the morning and rest in their roosting trees in the afternoon.
