Researchers found that marmoset monkeys, native to South America, use specific vocal calls, called "phee-calls", to identify and communicate with each other.

A study published in the journal Nature Ecology and Evolution in June showed that wild African elephants addressed each other with name-like calls, uniquely invented for each individual. Calls meant for other elephants did get responded to.
