A new study has found that orcas in captivity can imitate dolphin sounds. This makes orcas one of the few species that are capable of vocal learning. Researchers analyzed 10 captive orcas, seven who lived with only other orcas, and three who lived with only bottlenose dolphins. They discovered that the three orcas who interacted with only dolphins made dolphin-like whistles, clicks and buzzes, while the other seven orcas communicated almost entirely with typical whale pulses. The findings build on two-year-old research that showed that dolphins could similarly mimic sounds of whales and other animals.
