|A male Kirtland's Warbler from Wikipedia|
The endangered Kirtland's warbler is one of the rarest members of the wood warbler (Parulidae) family. It nests in just a few counties in Michigan, Wisconsin and the province of Ontario and nowhere else on Earth. The male Kirtland's warblers' summer plumage is composed of a distinctive bright yellow colored breast streaked in black and bluish gray back feathers, a dark mask over its face with white eye rings, and bobbing tail. The female's plumage coloration is less bright; her facial area is devoid of a mask. Overall length of the bird is less than six inches.
Kirtland's warblers typically nest on the ground in stands of jack pine between 4 and 20 years old. Historically, these stands of young jack pine were created by natural wildfires that frequently swept through northern Michigan. Modern fire suppression programs altered this natural process, reducing Kirtland's warbler habitat. As a result, the population of Kirtland's warblers declined to the point that they were listed as endangered.
The winter range of the Kirtland's warbler is in the Bahamas and in the Turks, Caicos, and Hispaniola islands. For more information on the Kirtland’s Warbler go to http://www.allaboutbirds.org/guide/Kirtlands_Warbler/id.
