Tiny Marsh Wrens live in wetlands, usually within cattails, reeds, or bulrushes. After choosing his territory, the male weaves up to 15 dome-shaped shells, lashing together cattails, grasses, or reeds. These are called "courting" nests. Then, sitting high atop a perch in the marsh, he sings, inviting a female to select a nest in his territory. once the female has chosen one of his shells, she lines it with cattail down, feathers, leaves, or grass and lays her eggs. Sometimes a second female chooses a nest on the opposite end of his territory.
