The Marsh Wren (Cistothorus palustris) is a small North American songbird of the Wren family. It is sometimes called Long-billed Marsh Wren to distinguish it from the Sedge Wren, also known as Short-billed Marsh Wren.
Adults have brown upperparts with a light brown belly and flanks and a white throat and breast. There is a black and white triangular patch on the upper back. They have a dark cap with a white line over the eyes and a long black bill.
The male’s song is a loud gurgle used to declare ownership of territory; western males have a more varied repertoire.
Their breeding habitat is marshes with tall vegetation such as cattails across North America. In the western United States, some birds are permanent residents. Other birds migrate to marshes and salt marshes in the southern United States and Mexico. [Wikipedia]
A common and noisy inhabitant of cattail marshes, the Marsh Wren sings all day and throughout the night. [All About Birds]

- Eastern and western populations of the Marsh Wren show slight differences in appearance, but large differences in song. In general, western birds are paler and drabber and sing less musical songs. The differences may mean that the two forms are separate species.
