- The Palm Warbler is found in two different forms. Birds that breed in the western part of the range are duller, and have whitish bellies. Those breeding in the eastern part of the range are entirely yellow underneath.
- Despite its tropical sounding name, the Palm Warbler lives farther north than most other warblers. It breeds far to the north in Canada, and winters primarily in the southern United States and northern Caribbean.
Breeds in bogs, open boreal coniferous forest, and partly open situations with scattered trees and heavy undergrowth, usually near water. Found in migration and winter in a variety of woodland, second growth and thicket habitats, on the ground in savanna and open fields, and in mangroves.
Insects; some seeds and fruits in fall and winter.

Palm Warbler populations are stable according to the 1966-2014 North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 13 million with 49% spending part of the year in the U.S., 7% in Mexico, and 100% in Canada. They rate an 8 out of 20 on the Continental Concern Score, and are a U.S.-Canada Stewardship species. Palm Warbler is not on the 2014 State of the Birds Watch List.
