A small, secretive wren that breeds in short grass and sedge marshes. Common foods include ants, bugs, beetles, grasshoppers, crickets, flies, mosquitos, moths, and caterpillars. Prolonged use of an area may depend on stable soil moisture regime. Perhaps because of the highly transitory nature of its nesting habitats, the Sedge Wren moves around a great deal from year to year, not staying in one place for long.
