The Pine Warblers have white bellies, two white wing bars, dark legs and thin, relatively long pointed bills; they have yellowish lines over their eyes. Adult males have olive upperparts and bright yellow throats and breasts; females and immatures display upperparts which are olive-brown. Their throats and breasts are paler.
The 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.
