Only male whales sing, and the tunes are thought to play a role in attracting mates and asserting dominance.<\/p>\n<p>Eastern Australia&#8217;s humpback whales were facing regional extinction in the 1960s, with only around 200 whales left.

Many humpbacks woo with a combination of singing and physical jostling, the Australia researchers report.<\/p>\n<p>&#8220;Such a big increase in animals over the time they were studying gave them a unique opportunity to get insights about changes in behavior,&#8221; said Simon Ingram, a University of Plymouth marine biologist in England, who not involved in the study.<\/p>\n<p>Ingram said that while humpback whales must have been singers long before whaling depleted their numbers, the new study highlights just how essential their elaborate and beautiful songs were to their survival and recovery.<\/p>\n<p>&#8220;Clearly singing became incredibly valuable when their numbers were very low,&#8221; he said.<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n                                                Rebecca Dunlop, Post-whaling shift in mating tactics in male humpback whales, <i>Communications Biology<\/i> (2023).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1038\/s42003-023-04509-7\">DOI: 10.1038\/s42003-023-04509-7<\/a>. <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s42003-023-04509-7\">www.nature.com\/articles\/s42003-023-04509-7<\/a><\/p><\/div>\n<p class=\"article-main__note mt-4\">\n                                                  \u00a9 2023 The Associated Press.
