The James L. Swiderski Memorial
Inscription.
The Kirtland's Warbler, one of the world’s rare birds. It is estimated that less than one thousand exist. They nest only in this portion of Michigan and winter in the Bahama Islands.
In Oscoda County, the U.S. Forest Service, Michigan Department of Conservation, Michigan Audubon Society, conservation clubs, forest industries and citizens are cooperating in efforts to preserve this warbler by improving the nesting range.
In Memory of James L. Swiderski, November 8, 1950 - May 5, 1980, Wildlife Biologist, who died while trying to help control the Mack Lake Fire, started by the U.S. Forest Service as a prescribed burn. The burn was to create an area of nesting habitat for the Kirtland's warbler. The fire then ravaged 25,000 acres of the Huron National Forest.
James was a wildlife enthusiast who was personally involved with and dedicated to the Kirtland's warbler management and recovery effort.
Erected 1963 by Citizens of Oscoda County.

Regarding Kirtland's Warblers Monument. The population of Kirtland's Warblers reached a low of less than 200 breeding pairs in about 1970. Cowbird trapping stabilized the species but it wasn't until the extreme burn event and further management that their population recovered enough to be removed from the federal endangered species list. There has also been range expansion to Wisconsin. In 2025, the population is estimated to be around 2500 pairs.

Due to a series of events, ignition of the prescribed burn was started later than planned. This, in combination with a frontal passage and increased winds, led to frequent spot fires. Eventually the fire spotted on the east side of Highway M-33.(Submitted on September 23, 2021, by J.T. Lambrou of New Boston, Michigan.)
