Did you know that wolves across the world speak in 21 different dialects, with differences depending both on species and location?

The largest-ever study of howling in the ‘canid’ family of species – which includes wolves, jackals, and domestic dogs – has shown that the various species and subspecies have distinguishing repertoires of howling, or “vocal fingerprints”.

The characteristic howls of red wolves, like Jack (M1606) featured in this video, usually include a series of barks, yips, and sometimes growling, especially when voiced in alarm. The red wolf’s howl sounds somewhat similar to a coyote’s, but is often lower pitched and lasts longer.
