What's in a quack?
To the untutored ear it might just sound like a load of quacking, but British researchers have discovered that the country's ducks - much like its people - have distinct regional accents.
Ducks from London make a rougher sound which resembles shouting so that fellow birds can hear them above the hubbub of city life, whereas their country cousins make a softer sound, the study found.
The differences were uncovered after academics at London's Middlesex University recorded the calls of ducks at a city farm in the capital and at a tranquil location in Cornwall, south-west England, the Guardian newspaper said.
There was a clear difference in sound, English language lecturer Victoria de Rijke told the paper, with the London ducks "much louder and (more) vocally excitable".
"The Cornish ducks made longer and more relaxed sounds, much more chilled out.
"The cockney (London) quack is like a shout and a laugh, whereas the Cornish ducks sound more like they are giggling," she said.
"London ducks have the stress of city life and a lot of noise to compete with, like sirens, horns, planes and trains."
The result was that the ducks' accents mimicked those of the humans in their home region, Ms de Rijke said.
She noted that the London accent tends to use short, more guttural vowel sounds whereas those in Cornwall are open and drawn out.
