Breeding Range. (Fig. 92). Common in the wooded valley along the Sheyenne River in northeastern Ransom County and northwestern Richland County; fairly common locally in other wooded areas in the Agassiz Lake Plain Region (including other valleys along the Red River and its tributaries, and the deltaic sand area of western Pembina County), in the Turtle Mountains, in the Prairie Pothole Region (Pembina Hills, and hills and lake shores in the vicinity of Devils Lake, and in valleys along the Sheyenne, James, and Mouse rivers and their tributaries), on the Coteau Slope (along the Missouri River between Garrison Dam and a point about 10 miles below Bismarck, and along the Missouri River and adjoining Yellowstone River extending upstream from Williston), and on the Little Missouri Slope (Killdeer Mountains and along the valley of the Little Missouri River); rare elsewhere in the state.
Breeding Habitat. Extensive tracts of bottomland and upland deciduous forest. Characteristic dominant trees in these stands include American elm, green ash, box elder, and bur oak. In the northeastern and eastern portion of the state, basswood and quaking aspen often are common associated species, and in western North Dakota, cottonwood is frequently predominant.
Nesting. Probable nesting season: Late April to mid-July. On May 29 [1961] a nest containing young birds was recorded in Stutsman County (RES). This nest was situated in an American elm and the opening of the nest hole was about 25 feet above the ground. Another nest containing four young was recorded on June 13 [1972] at the Fort Totten National Game Preserve (D. E. Goeke). Extreme dates of dependent flying young (4 records): May 30 [1969] in Stutsman County (P. F. Springer) to July 16 [1972] in Cass County (E. G. Anderson).
