Behaviour

Louisiana waterthrushes walk along stream edges, bobbing their tails and picking insects from rocks and water.

Why they matter

Louisiana waterthrushes depend on clean, clear streams and are a good indicator of stream health. They arrive in March, among the earliest warblers.

Reproduction and lifecycle

Nest — A cup in a stream bank among roots
Eggs — Usually four to six
Incubation — About 12 to 14 days
Chicks — Fed by both parents
Lifespan — Several years

Living around people

  • Keeping forested buffers along streams and preventing sediment runoff protects them.

Misconceptions

  • Waterthrushes are thrushes. They are warblers.
