# s-behav: mimic the sound of musk hogs to avoid being eaten

<< Bird or beast? A cuckoo seems to have learned how to mimic the sounds made by the pig-like peccaries it lives alongside, perhaps to ward off predators >>

<< Acoustic communication is particularly important in environments such as dense tropical forests, where the dim light constrains the efficacy of visual signals >>

<< In these environments, complex species interactions could promote the evolution of acoustic signals and result in intriguing patterns of mimicry and convergence >>

AA << demonstrate that the acoustic characteristics of bill clacking in ground-cuckoos are more similar to teeth clacking of peccaries than to bill clacking of the more closely related Geococcyx roadrunner >>
