Song of male humpback whales changes every year

[SanguineHorizon]

I recently heard on a travel show that the song of male humpback whales changes every year, but that all the whales sing the exact same song every year...

Any ideas on how this occurs?

Any ideas on how this occurs?

A gavering of whales to pass on a new song and then go and sing it. That might be try. Or magnetic waves that tell each whale what to do.

Just some ideas.

The female whales vote over what's to be the wooing song this year.
