Wild hippos can recognise their friends’ voices, according to a new study reported by the BBC. Scientists studying hippos at a nature reserve in Africa say the large mammals use sound to distinguish friend from foe and the animals can probably recognise individuals from their voices alone. “This recognition ability supports the social relationships between individuals,” said study leader Prof Nicolas Mathevon, from the University of Saint-Etienne in France. The “wheeze-honk”, the most common hippo call, can travel as far as 1km, according to the study.
