Palm Warbler (Setophaga palmarum)
Description: 5 1/2″ (14 cm) SPRING ADULT Eastern breeder has mostly olive-buff upperparts with faint streaking on back and two very faint, pale wing bars. Head has extensive chestnut crown, yellow supercilium, olive cheeks, and yellow throat with dark malar stripe; underparts are otherwise bright yellow, with rufous streaks on flanks. Western breeder has grayer back and wings; yellow is restricted to throat and undertail coverts. FALL ADULT AND IMMATURE Less colorful than their respective spring adult counterparts, lack rufous crown and streaks on flanks, are only lightly streaked above and have faint buff wing bars. Eastern breeder has yellowish supercilium and yellow wash to underparts; western breeder has white supercilium and gray underparts except for yellow undertail coverts.
Voice: Song a weak trill. Call a thin “tsip” or a sharp “chip.”
Habitat: 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.
Nesting: 4-5 eggs that are creamy white with dark speckles around large end. Open cup of weed stalks, grass, sedges, bark shreds, rootlets, and ferns, lined with fine grasses, bryophytes, and occasionally hair and feathers. Placed in sphagnum moss at base of short tree.
- 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
