What does the Marsh Wren sound like at night?
Press play. If that is the sound outside, you have your answer — the Marsh Wren's "chap-chap-chap cha-cha-CHURrr".
What you're hearing
Series of sharp introductory chips followed by an accelerating, mechanical buzz that ends abruptly; repeated every few seconds by territorial males.
“chap-chap-chap cha-cha-CHURrr”
Birders often file this one under Primary gurgling trill.
What time of night you hear it
Through the night in spring and early summer, from cattail marshes.
Migratory in the North—males arrive early spring to claim territories and build multiple nests; breeding May–July; southward migration August–October; winters in southern U.S. and Mexico.
Why a Marsh Wren calls at night
A gurgling, mechanical, sewing-machine rattle that simply does not stop. Marsh Wren males sing at night through the breeding season, and a marsh with several males can be genuinely loud at 2am.
What else could it be?
