The couple that sings together stays together: duetting, aggression and extra-pair paternity in a promiscuous bird species by Baldassarre, Daniel T., Greig, Emma I., Webster, Michael S.

“…When individuals mate outside the pair bond, males should employ behaviours such as aggression or vocal displays (e.g. duetting) that help assure paternity of…”
