A new study reveals that killer whales can learn to produce the same sounds that are produced by dolphins. The study showed that killer whales have an ability to imitate or reproduce the sounds that dolphins make to communicate. With this ability, the marine creature has joined the list of other species that can imitate sounds and can also use them in appropriate social context.
According to the researchers the ability to imitate sounds and use them in social ways is called "vocal learning". They said this ability has been extensively been studied in birds.
