Song is a loud, sweet series of clear introductory notes followed by a slurred phrase that rises and falls. The supercilium is thicker in Louisiana than in Northern, and tends to flare at the rear. You da man! Your email address will not be published. The ringing song of the Louisiana Waterthrush, in cadence so like the rushing streams that are its home, is one of the first signs of spring in eastern North America. On migration they sometimes use the edges of lakes and ponds if there is adequate vegetative cover. Brown above with a white eyebrow stripe that is wider at the rear. Next look at the shape of the eyebrow stripe, which broadens to the rear on Louisiana, and since it is also bright white on Louisiana this stripe can be very conspicuous (vs tapered behind the eye and usually yellowish on Northern). A quick judgment of the ground color of the breast and eyebrow stripe will separate most waterthrushes: bright white on Louisiana, yellowish on Northern. The converse (Louisiana appearing yellowish) never happens. The rest of us are just pedestrians. Long-legged warbler with an elongated body. Most waterthrushes are readily identified simply by the whiteness of the underparts. what do you think about the difference in primary projection as posted by jochen roeder and charlie moores in 2007? Found in forests near streams. It inhabits clear, moving streams in rich, broad-leafed forests. thanks for any comments. Its brown plumage and bold streaking help explain why this member of the warbler family has the word “thrush” in its name. Audubon's climate model projects a 97 percent loss of current summer range by 2080. Brown above and streaked below, but has fewer streaks on the breast (and particularly the throat) than similar Northern Waterthrush. The legs are bright pink. Loud ringing song carries well over rushing streams. The Louisiana waterthrush is migratory, wintering in Central America and the West Indies.

They are one of the earlier neotropical migrants to return to their breeding grounds in the spring, often completing their migration in late March or early April, which is almost two months before most other warblers reach their breeding grounds. The Louisiana Waterthrush has a large range, estimated globally at 2,400,000 square kilometers. It breeds in eastern North America from southernmost Canada and south through the eastern United States, excluding Florida and the coast. Native to the Americas and surrounding island nations, this bird prefers forest, shrubland, and wetland ecosystems. In a way, the Louisiana Waterthrush is the dipper of the East. dark lateral throat stripe more solidly colored and paler brownish, breast streaks brownish like back, blending with brownish sides to create more uniform appearance (vs streaks blackish, darker than back and still visible against paler olive-brown breast sides), streaks on flanks fewer and less distinct; broader and smudgy, blending slightly with buff flanks, and only two lines of streaks present (vs streaks on flanks still dark and distinct as on breast, and three to four lines of streaks on flanks), belly largely unmarked white (vs belly with lines of very fine streaks convering from breast and flanks, leaving only a small area unmarked), pale rear malar wrapping around onto sides of neck is clear and unstreaked (vs a few fine dark streaks on sides of neck), pale arc below eye often less well-defined (vs contrasting more abruptly with dark lower auriculars), throat usually unspotted, clean white (vs usually finely speckled with dark), tail bobbing motion tends to be slower, more circular, with some side-to-side motion and with slower downstroke and quick upstroke (vs motion averages faster, more nervous, generally straight up and down with less side-to-side, and quicker downstroke with slower upstroke), supercilium slightly buff-gray at front above lores (vs supercilium more nearly uniform in color all the way to the bill), upperparts slightly browner or grayer (vs olive drab on Northern), in the hand note mostly white undertail coverts with limited and irregular pale gray centers that are concealed (vs more extensive, more regular, mostly concealed dark gray bases of undertail coverts), legs often brighter pink (vs darker grayish, dusky pink), overall larger and heavier, with rounded belly (vs sleek and tapered body), head may appear relatively smaller, with high forecrown and sloped rear crown (vs relatively larger head with smooth flat crown on Northern), lower auriculars average paler and smoother brownish, contrasting with broad brownish eyeline (vs lower auriculars dark grayish streaked, not contrasting as much with dark eyeline), dark eyeline averages broader and more brownish (vs narrow blackish line), Louisiana may tend to hold head higher above back (vs Northern tends to hold head lower), Crown stripes – a suggestion that Louisiana may show more of dark lateral crown stripes was firmly refuted (ID-Frontiers messages Feb 1997). Forages along rocky forested streams, often venturing out to rocks in the middle of the stream. The Cornell Lab will send you updates about birds, birding, and opportunities to help bird conservation. Found along streams constantly bobbing its tail up and down as it walks. The global population of this bird is estimated at 260,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List. This site uses Akismet to reduce spam. Forages primarily on the ground alongside forested streams, or on rocks or downed logs in the middle of the stream. Call note of adults and juveniles is a very sharp, metallic chip.

Throat is usually unmarked. If that is the only part seen it could lead to an impression of yellowish underparts, but the breast, throat, and eyebrow are always clean white.
