Some like it loud: Warning coloration paved the way for louder, more complex calls in poisonous frogs

Species of poison frogs that utilize bright warning coloration as protection from predators are more likely to develop louder, more complex calls than relatives that rely on camouflage. New research indicates that because these visual cues establish certain species as unsavory prey, they are free to make noisy calls in plain sight and better attract possible mates.
