Strongly resembling the "Northern Waterthrush", however, the "Louisiana Waterthrush's" throat is unstreaked and its eyebrow longer, broader and whiter. Its legs are bright pink.
Plumage is similar to male and female, but young birds have buff underparts rather than white.
Arriving much earlier in Spring than the "Northern Waterthrush", the two species breed together in bogs and swamps and wet woodlands, near running water, in the eastern half of the United States from Minnesota and central New England south to Texas and Georgia.
Calls or song.
Their song consists of three clear notes followed by a descending jumble.
Population and distribution.
The "Louisiana Waterthrush" is migratory, wintering in Central America and the West Indies, and is a rare vagrant to the western USA.
"Louisiana Waterthrushes" nest in a rock crevice or amongst tree roots, laying 4–6 creamy white eggs in a cup of moss.
