Gorillas in zoos have come up with a way to communicate with humans

Captive gorillas have created a new kind of call to communicate with humans, writes Naked Science.
As noted in the article, animals rarely change vocalizations (the sounds they make). Basically, birds, bats, elephants and cetaceans are capable of changing the sounds they make, the authors of the material shared the details. Now American researchers have documented this behavior in gorillas.
The experiment involved 8 gorillas from the Atlanta Zoo. It turned out that the animals in most cases used a sound that is a cross between a sneeze and a cough – the scientists designated it as “hmm”.
At the same time, researchers have received a huge number of reports that other gorillas in zoos in the United States and Canada make similar sounds: a total of 33 animals in 11 locations, although this information has yet to be verified. As a rule, these sounds are made at the sight of a caretaker with food, so scientists have suggested that animals use such vocalizations to attract the attention of a person.
