Males defend a multi-porpouse territory from other males by singing. In North America, males may atract more than one female that builds it nest in the territory, while in South America males are monogamous and only one female per territory is observed.

Sexual Behavior

The Sedge wren is socially polygynous in North America, but socially monogamous in South America. The genetic mating system in both North and South America has not been described, but extra-pair fertilizations are likely in North and South America.
