New World warblers are small birds with short, thin, pointed bills. They inhabit vegetated areas and are generally very active, feeding by picking insects from the leaves or branches. The only resident species in Galápagos, the Yellow Warbler, is readily identified.
Unmistakable; the only bright yellow passerine in Galapagos. ADULT MALE: Upperparts olive-green, with some yellow edgings on darker wings and tail; face and underparts golden-yellow, with faint chestnut streaking on breast and flanks. Crown has reddish- brown patch, variable in size. ADULT FEMALE: Lacks the crown patch of male, and has olive head and upperparts, grey breast and pale yellow belly. JUVENILE: Generally greyer than female but with traces of yellow in plumage. Commonly seen in a Galapagos cruise.
Feeds on insects, caught by hawking like a flycatcher or by picking them off the ground.
