Breeding Range. The breeding population is restricted to a tract of ponderosa pine, covering several hundred acres, that is located on upland slopes near the Little Missouri River within townships T136N-R103W and T136N-R104W of Slope County. The first indication that the Audubon Warbler breeds in this particular area was based on an observation of one bird by Stanley G. Jewett on August 3, 1913 (Gabrielson and Jewett 1924). A definite breeding population was discovered here on June 21, 1967 by Kroodsma and Cassel (1968). At this time, eight singing males were recorded on territory, and on July 19, 1967 a specimen was collected. On July 28, 1969, Lewis W. Oring collected a juvenile female in this area.
