This amazing discovery, along with the recording of the vocalisation, was unveiled in a study published in the journal Proceedings of the Royal Society B.
The research team, led by José Zamorano-Abramson, postdoctoral researcher at the Pontifical Catholic University of Chile, began recording the 14-year mammal, named Wikie who resides at Marineland in Antibes, France, in 2014. The experiment was conducted to test the theory that killer whales learn sounds from social settings. Wikie, who has spent most of her life at the aquatic park, is accustomed to mimicking her trainer’s actions in exchange for fish, and was, therefore, the perfect candidate for the job.
The team began by presenting Wikie with sounds like noisy breath, a piercing peeping sound and the sound of an elephant call. Wikie stepped up to the challenge each time.
The ultimate test was to replicate human sounds like a few simple words: “Ah ah,” “hello,” “bye-bye,” “one-two-three,” and the name of her trainer, “Amy.” To their delight, she mimicked “hello” instantly. Though the others took a little longer, the smart mammal was eventually able to master them all.
Wikie is merely copying the sounds to obtain the reward that follows every attempt. However, this demonstrates the mammal’s intelligence.
