Cool Facts
- 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.
