The secret life of the Marsh Wren plays out under the cover of reeds. Males routinely mate with 2 or more females and build at least 6 dummy nests for every female they mate with. One male built 22 nests on his territory.

Marsh Wrens are tiny but fierce. They fight for resources and regularly pierce eggs and kill nestlings of Marsh Wrens and other birds.

Marsh Wrens are boisterous songsters that sing not only at dawn and dusk, but sometimes throughout the night. ~ All About Birds
