Marsh Wren (Cistothorus palustris)

This little bird, a Marsh Wren (Cistothorus palustris), was so busy building a nest when I saw him out at Swan Lake recently that it was difficult to snap a photo of him. I write "him" advisedly since nest building is a male activity of this species. The males commonly build one or several nests as lures to attract female wrens for breeding. Singing must also be a part of this activity since the only breaks he took from nest-building were to perch on this bull-rush and belt out a few tunes.
