|Conservation status||Status not well known, but no obvious declines in numbers. Would be vulnerable to loss of habitat, especially on wintering grounds.|
|Habitat||Poplar bluffs, muskeg, mixed woods near water; in migration, undergrowth. In breeding season, in United States and eastern Canada, prefers bogs with black spruce or tamarack. In western Canada nests on dry ridges, and in open poplar or aspen stands. In migration, found in undergrowth of lowland woods or in dense thickets in meadows.|
Forages mainly by walking on the ground, seeking insects among the leaf litter, sometimes flipping over dead leaves. Also walks along branches, picking prey from crevices in bark. In migration, may forage in small flocks with others of its kind.
Usually 4-5. Creamy white, with black, brown, or lilac spots. Incubation period and roles of the parents are not well known. Apparently only rarely parasitized by cowbirds. Young: Both parents apparently care for young; age at which they leave the nest is not well known.

Mostly insects. Details of diet not well studied. Undoubtedly feeds mostly on insects, like other warblers. Reported to feed its young on green caterpillars, also seen eating spiders, snails; may sometimes eat seeds and raspberries.
Males sing from trees to defend nesting territory. Nest: Hidden in sphagnum moss hummock. In poplar woods, placed next to bunch of dry grass or weeds. Nest is an open cup, constructed of leaves, grass, and bark strips, or sometimes a simple hollow in moss lined with finer stems of grass.
