Dolphins Use Whistles To Call Each Other By Name

Dolphins Use Whistles To Call Each Other By NameScientists have found further evidence that dolphins call each other by “name”. Research has revealed that the marine mammals use a unique whistle to identify each other.

‘Efficient system’

A team from the University of St Andrews in Scotland found that when the animals hear their own call played back to them, they respond. The study is published in the Proceedings of the National Academy of Sciences.

Dr Vincent Janik, from the university’s Sea Mammal Research Unit, said: “(Dolphins) live in this three-dimensional environment, offshore without any kind of landmarks and they need to stay together as a group… These animals live in an environment where they need a very efficient system to stay in touch.”


‘To stick together’

It had been-long suspected that dolphins use distinctive whistles in much the same way that humans use names. Previous research found that these calls were used frequently, and dolphins in the same groups were able to learn and copy the unusual sounds. But this is the first time that the animals response to being addressed by their “name” has been studied.

The team believes the dolphins are acting like humans: when they hear their name, they answer. Dr Janik said this skill probably came about to help the animals to stick together in a group in their vast underwater habitat. Dr Janik said that understanding how this skill evolved in parallel in very different groups of animals could tell us more about how communication developed in humans.

Duke And Duchess Of Cambridge Present Baby Prince To The World

Duke And Duchess Of Cambridge Present Baby Prince To The WorldThe Duke and Duchess of Cambridge have emerged from St Mary’s Hospital in west London with their new baby son. Walking out to cheers from staff and well-wishers, Kate cradled her son and said it was “a special time”. Prince William said they were “still working on a name”.

‘Very emotional’

A small crowd had gathered outside the palace to greet them. Speaking to reporters outside the hospital earlier, the couple both said the experience was “very emotional”. Kate handed their baby, who was wrapped in a white shawl, over to her husband and the couple walked forward to speak to reporters. They also revealed William had done the first nappy change.

Prince William was at the hospital for the birth at 16:24 BST on Monday, and stayed with his wife and son, who weighed 8lb 6oz (3.8kg), overnight.


‘Third in line to the throne’

Meanwhile, the birth of the third in line to the throne was marked by gun salutes at Green Park and the Tower of London and the ringing of bells at Westminster Abbey. And at Buckingham Palace, royal watchers and tourists queued in the rain to catch a glimpse of the bulletin – displayed on an easel – announcing the arrival of the royal baby.

The birth of the prince means the monarchy has three generations of heirs to the throne for the first time since 1894.
