Size

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).

Feeding

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

Habitat

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.

Behavior

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.
