Contribution to unravel variability in bowhead whale songs and better understand its ecological significance
Since the first studies on bowhead whale singing behaviour, song variations have been consistently reported. However, there has been little discussion regarding variability in bowhead whale singing display and its ecological significance. Unlike the better studied humpback whales, bowhead whales do...

Since the first studies on bowhead whale singing behaviour, song variations have been consistently reported.

Over the winter season 2013–2014, in an unstudied wintering ground off Northeast Greenland, 13 song groups sharing similar hierarchical structure and units were identified.
