Wolves howl in regional accents.
Wolves howl in different accents depending on where they live
University of Cambridge zoologist Dr. Arik Kershenbaum has explained that the sounds of the animals vary - with predators from Europe sounding different from their North American counterparts.
The scientist, who specialises in animal vocal communication, explained that European wolves have a flatter howl compared to North American creatures.
This means that wolves do not always understand each other if they encounter a predator from a different region.
Speaking on the Instant Genius podcast, Dr. Kershenbaum said: "We think that wolves in different parts of the world are really very, very different.
"So yeah, a European wolf might get a little confused if it hears an Arctic wolf and not know quite what to make of that."
