Romancing the Frog In túngara frogs, auditory and visual components of mate calling do not naturally occur together. Taylor and Ryan (p. 273 , published online 6 June) now show that two signals that are unattractive to female frogs when presented alone become highly attractive when presented together. In a kind of “perceptual rescue,” the unique combination of two signals increased the receiver's interest in the previously uninteresting signals.
