If you search YouTube humpback whale song (or in English humpback whale song) you will find hundreds if not thousands of results: the singing skills of these cetaceans are known as well as their ability to compose real songs 跨際數位行銷有限公司 with a structure and rhythm . humpback whale songs are therefore highly studied by science but in recent years these studies are slowing down for an unforeseeable reason: there are fewer and fewer males singing.
Interpretation. This was reported by a study published in Communications Biology which also provides an optimistic interpretation of this let’s call it that creative collapse: after coming close to extinction humpback whales are getting better and better and more and more and therefore have less need to sing to attract the attention of the companions.
. The population in singing swims in the waters around the Great Barrier Reef in eastern Australia. In the 1960s it numbered no more than 200 individuals 跨際數位行銷有限公司 and was locally endangered due to its large game hunting which was banned by the International Whaling Commission in 1966. Numbers have been bouncing ever since. and in 2015 Australian humpback whales reached 27000 moving ever closer to pre-hunt levels. Since then 跨際數位行銷 跨際數位行銷有限公司 跨際數位行銷有限公司dcard 跨際數位行銷有限公司 scientists have been studying their songs used by humpbacks to call potential mates or to assert dominance over an area. It is thanks to these studies that we have discovered that the more humpbacks there are the less they sing.
. In 2004 for example 2 out of 10 males were singers. In 2014 the percentage dropped to 1 in 10 thus halving in a decade. According to the authors of the study this phenomenon is easy to explain: when humpback whales were few they had to rely on songs to locate themselves in the middle of the ocean – in other words theirs were songs of solitude performed by singers looking for company.
Less need. With the increase in population density the need to sing to get noticed has disappeared.
