Chestnut-sided Warbler—Uncommon to rare summer resident of deciduous forest edges and secondary growth in the Turtle Mountains and Pembina Hills. Fairly common to uncommon migrant throughout the eastern third; rare farther west.
Ovenbird—Common migrant and fairly common to uncommon summer resident of mature deciduous forests (especially bottomland forest) in scattered areas throughout. Look for it in summer along the Little Missouri River in both units of the Roosevelt Memorial (check the campgrounds and picnic areas), at Sully’s Creek and Little Missouri Parks, Tasker’s Coulee, J. Clark Salyer Refuge, throughout the Turtle Mountains and Pembina Hills, Sully’s Hill Game Preserve, Stump Lake Park, along the Missouri River at Bismarck (Sibley Island area), and in the bottomland forests of the Sheyenne River in [Ransom] and [Richland] Counties.
Northern Waterthrush—Fairly common to uncommon summer resident of wood-bordered bogs, swamps, streams, and lakes in the Turtle Mountains, Pembina Hills, and on the south side of Devils Lake. Fairly common migrant through similar habitat over most of the state.
Mourning Warbler—Uncommon summer resident of forests containing an abundance of secondary growth in the Turtle Mountains and Pembina Hills. Fairly common to uncommon migrant over the remainder of the eastern half; rare in the western half.
Bobolink—Fairly common summer resident of tall and mid-grass prairies, alfalfa and other hayfields, and retired croplands throughout. Easy to find at almost any prairie area. Slightly harder to find in the southwest quarter but try Bowman-Haley and Lake Ilo Refuges, and meadows and alfalfa fields along the Missouri River in [Morton] County.
Western Meadowlark—Common to abundant summer resident (a few winter) of open country throughout. This is the state bird of North Dakota and is the only meadowlark present. If you miss this one, you are birding with your eyes and ears closed!
Yellow-headed Blackbird—Common summer resident of cattail and bulrush marshes and lake edges throughout. Less common in the southwest quarter. Hard to miss at such places as Kelly’s Slough, the marshes around Burnstad, Rush Lake, and Des Lacs, Lostwood, Upper Souris, J. Clark Salyer, Audubon, Lake Ilo, Bowman-Haley, Long Lake, Slade, Arrowwood, and Tewaukon Refuges.
Orchard Oriole—Fairly common to uncommon summer resident of forest edges, farmyards, shelterbelts, orchards, and residential areas throughout the southern half. Uncommon and local in similar habitat throughout the northern half. Some specific spots include wooded ravines and bottomland forest edges in the south unit of the Roosevelt Memorial, Sully’s Creek Park, the residential areas of Kenmare, the wooded area near the Des Lacs Refuge headquarters, the Sibley Island area at Bismarck, wooded draws surrounding Lake Ashtabula in [Barnes] County, and at Clausen Springs.
Northern Oriole—The predominant race, the Baltimore Oriole, is a fairly common summer resident of deciduous woodlands, shelterbelts, farmyards, and residential areas throughout the eastern two-thirds (uncommon to rare west of Bismarck). Not hard to find. The other race, the Bullock’s Oriole, is very restricted. It is uncommon and local in riparian stands of cottonwoods in [Billings], [Slope], and [Bowman] Counties. Look for it at Sully’s Creek Park, in the residential areas of Marmarth and Medora, along the river and at the campgrounds and picnic grounds in the south unit of the Roosevelt Memorial, and along wooded portions of the Little Missouri River south of Marmarth.
Rusty Blackbird—Uncommon migrant and uncommon to rare winter visitor to bottomland forests, wood lots, and farmyards throughout.
