The Louisiana waterthrush (Parkesia motacilla) is a New World warbler found in eastern North America and the West Indies and Central America during the winter. It is plain brown on top and white underneath, with black streaks and buff flanks and undertail, which distinguishes it from the closely related northern waterthrush.

Louisiana Waterthrush Description
Ground warbler with dark olive-brown upperparts and highly streaked white underparts with a buff wash on the belly and flanks. Whitethroat; dark and thick eyestripe; white brows spread behind eyes. Bill is lengthy and substantial. Tail is short and pale buff in color, with pale buff under tail coverts.
These birds have a length of 6 in (15 cm) and a weight of 20 g (0.7 oz). Their wings could range from 9 in (23 cm).
They feed on the adults and larvae or nymphs of caddisflies, mayflies, midges, soldier flies, craneflies, lacewings, stoneflies, butterflies, moths, aphids, dragonflies, damselflies, and beetles (of numerous species), as well as millipedes, woodlice, cicadas, scorpions, spiders, crayfish, earthworms, minnows
Louisiana waterthrushes are nearly entirely restricted to mature riparian woods. The typical habitat is steep-sided valleys with swift-flowing streams with stony stream banks and riffles.
Louisiana waterthrushes exhibit behaviors that are comparable to those of northern waterthrushes. These birds frequently sing from branches or while flying. Both species also have a tendency to bobble their tails in a teetering attitude, particularly when hunting. This is a critical behavioral trait of waterthrushes, as the genus name Seiurus translates as “tail-bobber.” Louisiana waterthrushes stroll rather than hop along the forest floor. They fly quickly, directly, and somewhat undulating, with rapid wing beats.
