Distribution
Palm Warblers breed in open coniferous bogs and edge east of the Continental Divide, across Canada and the northeastern United States.These birds migrate to the southeastern United States, the Yucatán Peninsula, islands of the Caribbean, and eastern Nicaragua south to Panama to winter. They are one of the earlier migrants to return to their breeding grounds in the spring, often completing their migration almost two months before most other warblers.
Palm Warbler has been recorded as a vagrant to Iceland.
Behavior
Palm Warbler nests take the form of an open cup, usually situated on or near the ground in an open area.Palm Warblers forage on the ground much more than other warblers, sometimes flying to catch insects. These birds mainly eat insects and berries. Their constant tail bobbing is an identifying characteristic. Kirtland's, Prairie, and Palm Warblers are the only ''Setophaga'' species that incessantly bob their tails.
The song of this bird is a monotonous buzzy trill. The call is a sharp ''chek''.
