A Marsh Wren is busy making her nest.
A common and noisy inhabitant of cattail marshes, the Marsh Wren sings all day and throughout the night. They nest in a variety of marshes, especially with dense weeds.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.
