Irish Dolphins May Have a Unique Dialect
As part of a research project, student Ronan Hickey digitised and analysed a total of 1,882 whistles from the Irish dolphins and those4 from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories5. Of the categories, he found most6 were used by both sets of dolphins7 but eight were only heard from the Irish dolphins.
Berrow, a marine biologist, said the dolphins clicks are used to find their way around and locate prey. The whistles are communications. They do a whole range of other sound like barks, groans and a kind of gunshot, he said. The gunshot is an intense pulse of sound. Sperm whales use it to stun their prey.
References in local legend8 indicate there have been dolphins in the Shannon estuary for generations and they may even have been resident there as far back as the 6th century9.
