  Order Passeriformes
   Suborder Passeres - Oscines (Song Birds)
      Parvorder Passerida (Superfamily Passeroidea)
         Nine-primaried Oscines
            Family Parulidae - Wood-Warblers (New World Warblers)

  Passerines are generally smaller than non-passerines. They have a perching foot with three toes directed forward and the one backward with locking tendons to facilitate perching when their tendons are flexed. All passerines scratch by bringing the foot over the wing. Incubation ranges from 11 -21 days. Young hatch blind with little or no down and spend 10-15 days or so in the nest - development is rapid and parents provide care beyond fledging.
Oscines are passerines with complex syringeal musculature used to produce varied vocalizations. 
Passeroids include the Nine-primaried Oscines, pipits, Old World sparrows, and weavers.
Nine-primaried Oscines include New World warblers, icterids (New World blackbirds), emberizines (buntings), tanagers, cardinalines (cardinals), and fringillines (finches).
New World Warblers are small and mostly arboreal, nine-primaried oscines with slender bills. Many are sexually dimorphic with brightly colored nuptial plumages. More northerly populations are migratory.  Our most obvious permanent resident is the Pine Warbler. Northern Parulas and Yellow-throated Warblers are prominent breeding warblers. In winter, look for the most abundant North American warbler, the Yellow-rumped Warbler, the less abundant Palm Warbler and Orange-crowned Warbler. The Black-and-white Warbler is a common migrant. Many other warblers may be found on Seabrook during migration, especially in the fall when their identification may be difficult.
Mnioltilta - distinctive warblers with specialized foraging, related to Dendroica warblers.

   Black-and-white Warblers are early spring migrants. They are strongly patterned in black-and-white with wing bars, a conspicuous line above the eye, black streaks on the breast and males have a black throat (females have a pale throat but have a prominent white supercilium). They have wing bars and show white in the outer tail feathers when they fly. They are very creeper-like (scansorial) and feed on trunks and limbs.

  RANGE: The species is broadly distributed, ranging north along the Atlantic from coastal North Carolina to Newfoundland, then west across Canada to central Northwest Territories an Alberta, south to the Dakotas, east to the Great Lakes, then south again through Illinois, Missouri to central Texas and the Gulf coast. In the southeast they do not breed in the coastal plain from eastern South Carolina through Alabama but are breeders in the mountains and piedmont - even breeding into the upper coastal plain. The species winters south through the Bahamas, Central America and Caribbean to northern South America.
  BREEDING: Monogamous. Females build a cup-shaped nest , usually on or near the ground. It is a concealed open-cup placed under leaves or branches and consists of leaves, grass and other plant materials. It is lined with fine grass or hair. She lays 5 (4-5) eggs which she incubates for 10-12 days. Young are altricial and fledge after 8-12 days. Both parents feed young.
  DIET: The feed on insects and other invertebrates which they glean from bark of tree trunks and limbs like a nuthatch. They may flycatch.
  VOICE: Their voice is a high, thin series of two-syllable phrases with 5-10 repetitions "weesa weesa weesa weesa..." Call a sharp "stick." Their song may help locate them in the spring.

   SCBBA: Possible breeding recorded in Beaufort, Georgetown, and Horry Counties. Inland?
   P&G: Fairly common during migration. Uncommon winter visitor. Very rare summer vagrant. Maximum: 40, Mt. Pleasant, 7-8 September 1962 (TV tower kill). Upstate dates: 19 March - 11 November. Egg dates: 27 April - 11 May.
   M&P: Upstate breeder.
   Avendex: 7 records. May - June, September, December. Maximum, above.
   Potter: Most common as a migrant but present during every season. It breeds in the mountains and into the upper coastal plain, becoming uncommon in the lower coastal plain. Breeding birds arrive between mid-March and early April and depart by mid-October although some spend the winter. 
  ●  Fairly common migrants. We see them on the live oak trees along Capn' Sam's Creek and they should be found in most wooded areas on Seabrook, at least during migration. They are early migrants (look for them by late March). Note that they feed on the trunks and limbs more like nuthatches than warblers... They are truly scansorial.
