These whales are also known to vary their tunes from year to year, but just how many songs they have in their repertoire, or why they exhibit this behaviour at all remains unclear.

Bowhead whale songs are thought to be social calls or some sort of a reproductive fitness display. What's clear is that whales can learn these songs from each other.
