Cock of the Plains (Sage Grouse)
Although not seen by Lewis and Clark in North Dakota, sage grouse were locally
common in the central and southern portions of the Little Missouri National
Grasslands. This species is restricted to scrub prairie dominated by black sage.
As sage grouse habitat was converted to farmland, and black sage brush reduced,
North Dakota's sage grouse population declined. Sage grouse are now found only
in extreme southwestern North Dakota, particularly western Bowman and Slope
counties.
