The marsh wren is a small North American songbird of the wren family. It is sometimes called the long-billed marsh wren to distinguish it from the sedge wren, also known as the short-billed marsh wren. Marsh Wrens occupy wetlands filled with cattails, sedges, bulrushes, and Phragmites as well as cordgrass-filled saltmarshes year-round. In the winter they also use brushy thickets near wetlands, tidal salt-marshes, and weedy agricultural canals. Marsh Wrens pick insects and spiders from stems and leaves of marsh vegetation. They tend to forage close to water, but occasionally fly up to catch a passing insect. gurgling and buzzy trills. Though each note may only last for 1–2 seconds, they can carry on for up to 20 minutes, hardly ever repeating the same note. Males in the eastern United States sing a more liquid and less harsh song than males in the West. Eastern males begin each song with a nasal buzz, whereas western males begin with a sharp chuck. Western males also have a more complex set of vocalizations. Males and females call to alert each other of danger and to indicate their location. The call is a grating, somewhat buzzy chit. In flight, males and females give a longer series of nasal calls. Here is a link so you can hear the wonderful sounds of this bird.
