The story is accompanied recordings of moos of different cows from different parts of the country, all of which sound different. Is this really surprising? Have you ever heard an individual cow, or any other animal for that matter, make the same moo twice?

There’s also a comment from a linguistics lecturer, who on the Today programme interview on the piece said yes, it was indeed possible that animals from one part of the country may indeed sound a bit like each other but slightly different from the same animals elsewhere in the country, because just like humans, animals learn how to make their noises from the other animals around them.

Does it take research to work this one out?
