Sound familiar? Acoustic similarity provokes responses to unfamiliar heterospecific alarm calls
Eavesdropping on the alarm calls of other species can provide vertebrates with valuable information about danger, and often responses to heterospecific calls seem to be acquired through learning. However, animals might not require learning to respond to heterospecific alarm calls that are acoustically similar to conspecific calls. Although previous work suggests that learning is necessary for superb fairy-wrens to develop responses to heterospecific alarms, acoustic similarity might also be...[Show more]
