Riverside wren pairs jointly defend their territories against simulated intruders

This study is one of the few to demonstrate equal attention and aggression from mated pairs towards simulated same‐sex and opposite‐sex intruders. We suggest that pairs responding together, in close proximity to one another, might be favourable in duetting species when defending the territory because maintaining a close distance between partners facilitates the extreme coordination of their joint territorial signals.
