ANIMAL BEHAVIOR:
Dolphins Whistle a Signature Tune

Peter L. Tyack

Now, in his Perspective, Tyack discusses new findings showing that vocal imitation is important for communication among bottlenose dolphins in the wild (Janik). Apparently, bottlenose dolphins, when they are separated in the wild, address each other by matching each other's whistles.
