|BANGOR, Wales (Reuters) -- Dolphins living off the coast of Wales whistle, bark and groan in a different dialect from dolphins off the western coast of Ireland, scientists have discovered.|
Different physical environments might have contributed to the mammals developing distinctive sets of vocalizations or "dialects", said Simon Berrow from the Shannon Dolphin and Wildlife Foundation.
A better article from the Shannon Dolphin and Wildlife Foundation.
|As part of a recent research project, student Ronan Hickey digitised and analysed a total of 1,882 whistles from the Shannon dolphins and those from bottlenose dolphins in Cardigan Bay in Wales. He separated them into six fundamental whistle types and 32 different categories. Of the categories, he found most were used by both populations of dolphins, but eight whistle types were only produced by the Shannon dolphins.|
The new paper is Berrow, S.D., O’Brien, J. & Holmes, B. (2006) Whistle production by bottlenose dolphins Tursiops truncatus in the Shannon estuary. Irish Naturalists' Journal 28(5), 208-213.
I poked around a bit, but didn't locate an online copy of the paper.

Just cool stuff.
Lou FCD is still in school, so we should only count him as a baby biologist. -carlsonjok -deprecated
