Breeding Range. (Fig 105). Common in the wooded deltaic sand area of western Pembina County, in the Pembina Hills, in the Turtle Mountains, in the wooded hills and lake shores of the Devils Lake - Stump Lake area, in the wooded lake shores of Sargent County and southwestern Richland County, in wooded valleys along the Red and James rivers and their tributaries, and in the wooded valley along the lower Mouse River (within McHenry County and eastern Ward County); uncommon elsewhere in the Agassiz Lake Plain Region, in the wooded valleys along the upper Mouse River and Des Lacs River (within western Ward County, Renville County, and Burke County), and in the wooded valley along one sector of the Missouri River (between Garrison Dam and mouths of Apple Creek and Little Heart River); rare elsewhere in the Prairie Pothole Region, and on the Coteau Slope.
Breeding Habitat. Characteristic of deciduous forests throughout its range including floodplain and river bluff forests along major streams and extensive tracts of upland forest on some of the more prominent hills and escarpments. This species also inhabits mature tree claims, including groves of cottonwood.
Nesting. Probable breeding season: Late May to mid-September; probable peak, early June to late August. Singing males on territory have been recorded as early as May 27 [1962] and as late as September 13 [1962] along the James River in Stutsman County (RES). A nest found on June 27 [1964] in Pembina County along the Pembina River was situated on a dead limb of a bur oak, about 50 feet above the ground (RES). Adults were observed feeding flying young as late as September 10 [1970] in LaMoure County (H. A. Kantrud).
