Where you'll hear it

Breeds across southern Canada and much of the northern and western United States; resident year-round along Pacific Coast, Gulf Coast, and portions of the Southwest and Mexico.

Freshwater and brackish marshes dominated by cattail, bulrush, sedge, and reed; also wet meadows and rice fields.

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.

How to recognize it by sight

A tiny, energetic wren of marshes, the Marsh Wren scurries through cattails and bulrushes with tail cocked high. Rich chestnut-brown above with bold black-and-white streaking on the back and a crisp white eyebrow, it often remains hidden but its distinctive, buzzy song rings out day and night.
