Australian humpback whales are singing less and fighting more. Should we be worried?

As eastern Australian humpback whale populations have recovered over the years, males have adapted their mating strategy in a highly strategic way, new research finds.
123 days’ worth of data on Australian humpbacks (Megaptera novaeangliae), collected from 1997 to 2015 was analyzed, and found male humpbacks sang less and fought more as the whale population ballooned.
This shift in behavior is thought to be a result of not wanting to attract other males to a potential mate, as we explain in research published today in Communications Biology.
