This sector is known chiefly for its large concentrations of breeding waterfowl and for its prairie specialties, such as the Baird’s Sparrow. The density of nesting waterbirds (not just ducks, but also grebes, cormorants, herons, etc.) is truly spectacular, and the number and abundance of prairie specialties would warm the heart of any lister. Another dimension to this sector (in addition to the lakes, potholes, prairie grasslands, and wooded coulees) is the badlands habitat with many western species at the edge of their ranges.
Because of the unique blend of habitats, the northwestern sector is strongly recommended to the visiting birder for top priority. If you are limited in time, a tour of the North Unit of Theodore Roosevelt National Park and of the refuges around Kenmare should enable you to see most of the state’s specialties. While a visit between the months of September and April could be more profitably spent in some other part of the state, you could hardly go wrong in visiting here between May and August.
a) [Dunn] County
As mentioned, badlands habitat does exist in the northwest sector. Its easternmost extension is found around the Little Missouri State Park. To reach it, go north from the town of Killdeer on State Highway 22 for about 17 miles, turn right (east) at the sign for the park, and proceed to the camping area.
This is still a primitive area, and the campground is not developed. All trails are for hiking and horseback riding only. If your time is limited, forget this spot and go on to the North unit of Roosevelt Park. However, if you enjoy the peace and solitude of primitive areas, this is the place for you.
The park has not been birded much, so it is hard to say what you may find. Judging from the habitat, almost any badlands-type bird could be found. Some of the likely ones include Say’s Phoebe, Black-billed Magpie, Mountain Bluebird, and Lazuli Bunting.

North Unit Roosevelt Memorial
One of the most interesting and unique places to bird in the state has to be the North Unit of Theodore Roosevelt National Memorial. Most of the western species which inhabit the south unit can be found here also, and most birders who have visited both units agree that the north unit is better. This may be true partly because people-pressure is greater in the south unit, which lies right along the interstate.
