Waterthrushes
Warblers
The Waterthrushes are New World warbler. The two species are: ...
Waterthrushes sometimes incorporate mollusks and small fish into their insectivorous diet. They walk on the ground and in shallow water in search of prey bobbing their tails all the while.
Both waterthrush species walk rather than hop, and seem to teeter, since they bob their rear ends as they move along.

Northern Waterthrush
Seiurus noveboracensis
The Northern Waterthrush (Seiurus noveboracensis) nests across much of Canada as well as some areas of the northern United States.
Northern Waterthrush
Seiurus noveboracensis (Gmelin)
Status Fairly common in summer. Breeds. Normally arrives about mid-May (average 13 May, earliest 6 May); however, five sightings between 4 and 22 April have also been reported.
Northern Waterthrush (Seiurus noveboracensis)
The Northern Waterthrush breeds further north than the Louisiana Waterthrush in Alaska, Canada and northern USA. It winters in southern USA, Central America, northern South America and the West Indies.
The Northern Waterthrush breeds in forested wetlands and along sluggish waters, always in areas with dense cover. Wooded swamps, willow or alder thickets, boreal forest, and rhododendron stands along streams are some of its haunts.
The Louisiana Waterthrush is the less widespread and common of the two Waterthrushes (the Northern Waterthrush being the other).
Like most mortals, I can't tell a Louisiana Waterthrush from a Northern one. The experts recommend looking at the eyebrows, but that never helped me much.

There are of course exceptions. The Seiurus waterthrushes and Ovenbird are strongly migratory, but have identical male and female plumage, whereas the mainly tropical and sedentary yellowthroats are dimorphic.
AQUATIC WOOD-WAGTAIL (LOUISIANA WATER THRUSH).
[Louisiana Waterthrush.]
SEIURUS NOVAEBORACENSIS, Gmel.
[Seiurus motacilla.] ...
It might be confused with a sparrow but the bill is too narrow and the upperparts lack streaking and spotting. Other ground-dwelling warblers with streaked underparts are the waterthrushes but they constantly wag their tails and have white or yellow ...
along with reports of a Northern Waterthrush and a Black-and-white Warbler

early post-breeding dispersal/migration following the arrival of the recent
cold front.
