Marsh Wren — Habitat

Marsh Wrens prefer wetland habitats featuring dense cattails, reeds and bulrushes. These birds eat mainly invertebrates, especially spiders and insects including bees, ants, wasps, beetles, dragonflies, damselflies and moths. Marsh Wrens forage on or near the marsh floor, gleaning insects from stems and leaves of vegetation and from the water’s surface. Some wrens may also forage in thickets or shrub patches that occur near the marsh.
