- •
We studied acoustic and visual signals of species discrimination in two wren species.
- •
We presented hetero- and conspecific song playback and visual models to birds.
- •
We investigated responses of both males and females to song and model presentation.
- •
We found that wrens rely heavily on acoustic signals and little on visual signals.
- •
We report asymmetrical aggression consistent with interspecific dominance.
