Recognition of other species' aerial alarm calls: speaking the same language or learning another?

Magrath, Robert D; Pitcher, Benjamin James; Gardner, Janet

Description

Alarm calls given by other species potentially provide a network of information about danger, but little is known about the role of acoustic similarity compared with learning in recognition of heterospecific calls. In particular, the aerial 'hawk' alarm calls of passerines provide a textbook example of signal design because many species have converged on a design that thwarts eavesdropping by hawks, and call similarity might therefore allow recognition. We measured the response of fairy-wrens...[Show more]
