Behaviour

Sedge wrens are secretive, staying low in grass. They move around unpredictably in summer, nesting wherever conditions suit.

Why they matter

Sedge wrens depend on wet meadows, which have been drained widely. Their nomadic nesting habits make them one of the least predictable songbirds.

Reproduction and lifecycle

Nest — A ball of woven grass in dense sedge
Eggs — Usually five to seven
Incubation — About 12 to 14 days
Chicks — Fed by both parents
Lifespan — A few years

Living around people

  • Wet, grassy field corners left unmown help them in winter.

Misconceptions

  • All marsh wrens are the same. Sedge and marsh wrens use different habitats.
