Northern Prairie Wildlife Research Center
Forty-seven bird species were recorded on 30 wooded draw census plots in five western North Dakota counties. An additional 23 species were recorded in habitats adjacent to wooded draws. The most frequently occurring species were Rufous-sided Towhee, Brown-headed Cowbird, House Wren, and American Goldfinch. Wooded draws in the McKenzie-Williams County area seemingly supported higher mean breeding densities than did draws in the eastern half of the area.
