Sympatric species diverge their calls to prevent hybridization

Evidence

The species recognition hypothesis (SRH) supposes that species living in sympatry try to reduce the risk of utilizing similar sonic traits that could confound species reproduction and create the risk of hybridization. — Almo Farina, Soundscape Ecology, 496
