The Kirtland's Warbler is a small songbird in the warbler family. They have bluish grey faces and backs, with yellow throats and bellies. Females are duller than males. They are often seen pumping their tails.
The species requires a very specific habitat for breeding: large areas of young jack pine trees. Due to habitat loss, the Kirtland's Warbler was nearly extinct just 50 years ago. They are highly suspectible to parasitism by Brown-headed Cowbirds as well. Today, through conservation work, the bird is recovering, but still rare.
The Kirtland's Warbler breeds in areas of Michigan, Wisconsin and Ontario. The birds spend the winter in the Bahamas and other islands of the West Indies.
Kirtland's Warblers feed on insects gleaned from small trees, and small fruits. They build their nests of open cups on the ground using grass, plant material, and pine needles.
