Marsh Wren
Scientific Name: Cistothorus palustris
This small, singing bird clings to stalks of tall grasses and cattails, its tail poking straight up. The courting male builds several crude nests which are used, if at all, only for roosts. Later, the wren pair cooperates in construction of a proper nest—a ball woven of cordgrass leaves, lined by the female with shreds of vegetation, feathers, or other soft materials.
Size: 4 to 5.5 in. (10 to 14 cm)
