High-pitched, eerie and yet distinct, the sound of a voice calling the name “Amy” is unmistakable. But this isn’t a human cry – it’s the voice of a killer whale called Wikie.
New research reveals that orcas are able to imitate human speech, in some cases at the first attempt, saying words such as “hello”, “one, two” and “bye bye”.
Scientists say the discovery helps to shed light on how different pods of wild killer whales have ended up with distinct dialects, adding weight to the idea that they are the result of imitation between orcas. The creatures are already known for their ability to copy the movements of other orcas, with some reports suggesting they can also mimic the sounds of bottlenose dolphins and sea lions.
“We wanted to see how flexible a killer whale can be in copying sounds,” said Josep Call, professor in evolutionary origins of mind at the University of St Andrews and a co-author of the study.
