The year 1981 marked the 30th anniversary of the first census of Kirtland's warblers (Dendroica kirtlandii). This is the eleventh consecutive annual census. From mid-May to mid-June, cooperators spot-check those areas which appear to contain suitable habitat for the presence of singing male warblers. Those found to have birds present are censused during a ten-day period in mid-June (June 5 to 14 in 1981). The 1981 census of Kirtland's warblers indicated about a 4.5 percent drop in the population with a total of 232 singing males tallied this year compared to 243 in 1980. In 1981, no males were located outside of the traditional breeding range in northeastern lower Michigan.

In 1951, Harold Mayfield organized the first census of the species - a project generally recognized as the first such undertaking for any songbird. Since that time, thirteen more censuses have been carried out; the first three at ten-year intervals and since 1971, annually. The highlight of the 1982 census was the discovery of the first Kirtland's warbler ever found in the Upper Peninsula. Dr. John Probst, ecologist with the U.S. Forest Service. found one singing male near Gwinn. Overall, workers tallied 207 singing males, all in Michigan. This represents a drop of 25 (10.8 percent) from the 1981 count of 232, and 14.8 percent less than the 243 males found in 1980. The 1980 count was the highest in the entire series from 1971 to 1982, but still well below the 432 present in 1951 and the 502 in 1961.
