Killer whales can learn new languages like humans | T4 Magazine

Killer whales can learn new languages like humans | T4 Magazine | SA Scuba Shack | Scoop.it
The animal kingdom is filled with a flurry of sounds that are hard-coded into the DNA of that particular animal (that’s why cats don’t bark). But, some species, including humans, can imitate or learn news sounds/languages within a given social context. 

Two researchers have discovered that killer whales are capable of cross-species vocal learning by imitating their social environment. When housed alongside bottlenose dolphins, killer whales (orca) adjusted their vocals to more closely match their social partners.

The vocabulary of a killer whale consists of a complex vocal mix-up of clicks, whistles and brief bursts of sounds. Different social groups of orca have different pitch, duration, and pulse pattern that is unique to that particular group of killer whales. This distinct vocal characteristic is known as a ‘dialect’. 

“There’s been an idea for a long time that killer whales learn their dialect, but it isn’t enough to say they all have different dialects so therefore they learn. There needs to be some experimental proof so you can say how well they learn and what context promotes learning, “ said Dr. Ann Bowles, senior research scientist at Hubbs-SeaWorld Research Institute.

Research indicates that killer whales are able to learn a completely new sound: one killer whale living with dolphins leaned to imitate a chirp sound that was taught to the dolphins by their trainer. Such evidence points to the amazing social characteristics of killer whales, but their magnificence is often short lived due to endangerment from human activity.
