  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.
Ground-walking Warblers (Seiurus). These warblers are characterized by thrush-like patterns. They are terrestrial, walking on the forest floor or along a stream or pond. They have loud songs and call notes that reveal their presence.

     There are two waterthrushes, two warbler species that are difficult to distinguish in the field. While their breeding ranges are largely non-overlapping (allopatric), we find both in our area during migration - although both are relatively uncommon..
Here are pictures and traits that are useful in their identification:

Trait Northern Waterthrush Louisiana Waterthrush
Supercilium Narrow, white behind the ear bold, white behind the ear
Supraloral (eye-bill) white buffy
Throat some small spots unspotted white
Breast streaks dense, black streaks fewer, brownish streaks - not dense
Breast, belly color yellow wash, yellow or buffy flanks white, buffy flanks
Legs less pink bubble-gum pink (spring)
Behavior rapid tail bobs bobs tail slowly, semicircular pattern
Habitat bogs, ponds flowing streams
Call Note loud spwik, rising with stong K sound loud spich, not as hard
     Unfortunately, some "whitish" adult Northern Waterthrushes lack the yellow wash and are difficult to distinguish - look at the streaks and supercilium - and good luck!
