Goats have accents which they pick up from their peers


Where do they get these stories from? You've heard of the North-South divide where there are clear regional differences in things like food, economics, general habits, and accents. This divide tends to translate to a generally harder voicing of consonants and vowels in the mother tongue and can be heard in countries as diverse as Italy, Thailand, the UK and China.

It's surprising then that this also appears to happen among the animal population, well goats anyway and we've always assumed that one goat sounds much like another. But we'd be wrong, claim researchers – because while their vocabulary may be limited, the animals bleat in different accents.They discovered pygmy goats had a distinct bleat according to the herd they lived in, developing a similar sound to their peers as they grew up.
 
The researchers, from Queen Mary, University of London, now believe regional accents among mammals are much more widespread than previously thought.They followed four separate herds of baby pygmy goats, recording them with a hidden microphone over several weeks.

At first, the baby goats stayed with their mothers and siblings and copied their sounds. But as they grew older and formed social groups with their peers – known as ‘creches’ – their voices became more uniform.

This suggests the noises they make can change with their social environment rather than being solely determined by genes, as previously thought.

Dr Elodie Briefer and Dr Alan McElligott recorded the noises made by the goats – all farm-bred in Nottinghamshire – at around a week old and again at around five weeks.
They analysed the sounds they made and discovered each herd had its own ‘accent’. They believe the differences between herds born further apart would be even greater. Dr McElligott said: ‘Goats have a very limited vocal repertoire, they only have a couple of types of call. ‘But yet we found these variations, which suggests they may be a lot more intelligent than we thought. The findings were published in the journal Animal Behaviour.

So now you know: when you see two goats in a field bleating together, like us, they may not be understanding each other because of regional differences!
