HABITAT DESCRIPTION:
In North Carolina, breeds only in the mountain region (Pearson 1959).

Inhabits brushy areas in over-grown fields (Pearson 1959), heath balds (Kendeigh and Fawver 1981), mountain laurel thickets, thickets of young chestnuts (Dunn and Garrett 1997), and sapling-sized clear-cut areas (Mitchell and Stedman 1993); can also be found within mature deciduous or coniferous forests wherever there exists a brushy place with a gap in the canopy due to fire, windfallen trees, blight, logging, etc. (Stupka 1963, Alsop 1991). In the spruce-fir zone, birds breed in mountain ash saplings, which often sprout in these gaps, and also where the spruce and fir are in early successional stages (Kendeigh and Fawver 1981).

Nests are well-concealed, placed low (1-3 feet above ground) in a shrub, tangled vine (Griscom and Sprunt 1957), or sapling (Dunn and Garrett 1997). The warblers forage in the bottom half of shrubs and in the lower branches of tall trees, where they glean insects and spiders, and occasionally seeds and berries (Curson et al. 1994).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Open deciduous woodland, forest edge, second growth, and brushy areas; in migration and winter also in various forest, woodland, scrub, and thicket habitats (AOU 1983). Common breeder in mountains over 1050 m; occurs down to 600 m elevation (Hamel 1992). Winters on the edges of and in disturbed parts of lowland forest (Pashley 1989).

Nests in fork in sapling, shrub, thicket, or vine tangle, within about 1 m of ground (Harrison 1978).
