Found almost exclusively in pines where it is often the commonest warbler. Feeds primarily on seeds. On migration can be found anywhere and will feed on the ground, often with PAWA. An early migrant in spring, late in fall. Wintering birds often in mixed flocks with warblers, bluebirds, and CHSP in parks, golf courses, etc. Song a trill, with nicer tone than tinny CHSP. Frequently gives a hard chip note. ID: Variably colored and can be particularly nondescript and confusing. A large, sturdy warbler heaviest in the belly and with a long tail, often with a distinct fork (it recalls CHSP in flight). Thick-necked and round-headed. All plumages show broken eyering and pale lores on otherwise bland face with pale area behind ear coverts. Also bold wing bars, unstreaked back, and diffuse streaks on breast sides. Short primary projection and wing point. Ad ♂: yellow and green with faint streaking. Ad ♀/1st-yr ♂: duller yellow on breast and back mixed with brown. 1st-yr ♀: pale brown. ID from BBWA and BLWA straightforward: shape, head pattern, color, and always confirm with unstreaked mantle if in doubt. From drab CMWA by bold wing bars and shape.
