Recordings with a fixed hydrophone at a location high up north in the Arctic show Icewhales displaying a great diversity of complex whale songs in the middle of the dark polar winter, year after year. It seems that Icewhales gather in open leads within dense sea-ice. The sophisticated whale songs presumably play a role in courtship and mating behaviour as a kind of singer-songwriter contest. Until now, hardly anything is known about Icewhale reproduction.
