Kirtland’s Warblers can be spotted at Hartwick Pines State Park, and tours are offered by the Michigan Audubon each year. During the winter the songbirds leave Michigan for the Bahamas.” The recovery of the species testifies to the effectiveness of habitat restoration efforts. From an all-time modern low of 167 nesting pairs in 19, the summer population of the warbler rebounded to more than 1,700 pairs in 2007. In addition, cowbird populations were controlled. Guided by research to mimic natural fire processes, government agencies and private conservationists began harvesting older jack pine stands and replanting the trees to restore the warblers’ habitat. The warbler was placed on the federal endangered species list in 1967 and the state endangered species list in 1976.
Kirtland’s Warbler faced extinction due to the loss of habitat and the invasion of parasitic brown-headed cowbirds, which lay eggs in warbler nests and whose young survive at the expense of warbler nestlings. Such forests in northern Michigan became their prime global summer breeding habitat.
The birds originally depended on fire-created young jack pine forests for summer nesting. We learned a lot about the Kirtland’s Warbler from a Michigan historical marker at the I-75 northbound rest area near Grayling: “The Kirtland’s Warbler was first identified in 1851 from a specimen collected on Dr.
Today we will take a look at the history of this bird as well as look at what the plate raises funds for and how you can get one. Like the elk and loon, the Kirtland’s Warbler is a Michigan conservation success story and that’s why we think it’s an excellent choice and we continue to love seeing funraising directed towards Michigan lighthouses and other causes. The Michigan DNR recently announced an exciting change for 2022: The Kirtland’s Warbler will be replacing the Elk on the “Conserve Wildlife Habitat” license plates! From 2001-2018 these plates featured the Loon, then the Elk took over in 2018 to coincide with the 100 year anniversary of the elk’s reintroduction in Michigan.
