Rock Wren

Several years ago, Rock Wrens were a highlight of the combined meetings of the South Dakota Ornithologists’ Union and the North Dakota Bird Society in the Theodore Roosevelt National Park in southwestern North Dakota. This wren inhabits rocky and craggy habitat across most of the western United States and Mexico, spilling over to both adjacent Canada and Central America. Rock Wrens nest in crevices, and often build curious walkways of small, flat stones that lead to the otherwise hidden nests (Lowther et al. 2000). This Rock Wren sang boisterously and in the open high above the Little Missouri River.
