HABITAT DESCRIPTION:
Occurs throughout the state from the lower altitudes of the mountain region east to the barrier islands (Fussell 1994, Fussell and Lyons 1990, Potter et al. 1980, Price et al. 1995, Stupka 1963)

Prairie Warblers are always associated with deciduous or mixed successional habaitats such as open hillsides (Stupka 1963), brushy fields (Simpson 1992), thickets, second growth clearings (Potter et al. 1980), forests edges (Ehrlich et al. 1988), power line cuts, abandoned orchards, or reclaimed strip mine sites (Dunn and Garrett 1997). Especially on the coastal plain, inhabits young pine forests with brushy cover (Fussell 1994). Other likely habitats on the coastal plain are dune vegetation, ridgetops, cliff edges, and open pine and oak barrens, preferably on dry upland slopes with sandy soil. Avoids forests with closed canopies (Dunn and Garrett 1997).

The nest is built about 4 feet from the ground (ranges 1-10 feet) in a bush or sapling (Griscom and Sprunt 1957). The nest is placed on a horizontal or diagonal limb, in a fork, or against the trunk, and rarely in a tangle of vines (Ehrlich et al. 1988, Nicholson 1997).

NATURE SERVE GLOBAL HABITAT COMMENTS:

BREEDING: Brushy second growth, dry scrub, low pine-juniper, mangroves, pine barrens, burned-over areas, sproutlands. Small patches of habitat may be suitable for breeding. Subspecies DISCOLOR primarily inhabits various types of shrubby vegetation: brushy second growth, dry scrub, low pine-juniper, jack pine stands, pine barrens, coastal pine subclimax, christmas tree farms, burned-over or cut-over areas, sproutlands, grassland-forest ecotone, powerline corridors, inner forest of Great Dismal Swamp, corridors in hardwood swamps, revegetating strip-mined lands, overgrown apple orchards, and abandoned fields in the breeding season. Many of these habitats are early successional and are suitable beginning about 5 years after burning or clearing and continuing for about 10-20 years.

Nests usually in a shrub, sapling, thicket, or fern clump, usually 0.3-3 m above ground, occasionally higher (Harrison 1978). In western Massachusetts powerline corridors, nests were 1-3 m above ground in vegetation clumps (1-10 m in diameter) of scrub oak, alder, or meadowsweet; nest locations had 30-100% cover (Houlihan, pers. comm.). In northern Arkansas, nesting areas included old fields invaded by cedars, locusts, sweetgum, persimmon, and pawpaw (Dechant, pers. comm.).

The following data are from Breeding Biology Research and Monitoring Database (BBIRD) sites in Arkansas plantations, where nests were mainly in hickory, elm (mostly winged), blackgum, oak, red maple, and vaccinium (D. Barber and T. Martin, unpubl. data). Mean values for nest site characteristics in thinned and young plantations were, respectively, 52 and 66% side cover, 67 and 80% overhead cover, 2.6 and 1.5 m nest height, 3.2 and 2.4 m plant height, 4.1 and 3.5 cm plant dbh, and presence of 8 and 13 small (<2.5 cm) and 70 and 54 large woody stems in a 5-m radius surrounding nests.

NON-BREEDING: In migration and winter, occurs in various woodland, second growth, brush, and thicket situations. Winter is spent mainly in arid lowland forest or scrub, especially second growth, pine, pastures, brushy fields; mangroves, shade trees, sun coffee, and forest edge also are used (Lack and Lack 1972, Arendt 1992). More common in dry forest of introduced mimosaceous trees at Cabo Rojo National Wildlife Refuge (where insects more abundant and birds had higher fat scores) than in dry forest of native species in Guanica (Baltz, pers. comm.). Across the Caribbean region, shows moderate habitat specialization (Wunderle and Waide 1993). In winter in Puerto Rico, September-March, individuals showed strong site fidelity within and between seasons (nearly 50% returned for a second winter, 40% a third winter).
