Whales sing when they have had a good meal says research

Hampback Whale sings a song in a fiery manner in the huge ocean. These songs are beautifully quite complex, and in these phrases and themes are woven into excellent compositions. Blue and Finn Whale fill the sea with notes with their own unique songs. These three species of whale can jointly produce amazing music in the sea. But why do these whales sing songs, what is the reason behind this. This has been revealed in a research.

Plos one Our new published in Research It is revealed that these Balen whale species have a special reaction that expresses them to major changes in their ecosystem, and they can be heard in their songs. The six -year study was done in the whale dinner in the eastern Northern Pacific region, away from the coast of California in the United States. This area is biologically rich in whale food. From here, whales travel long distances every year and migrate to breeding houses at lower latitudes.

They eats too little or nothing during their migration and winter breeding season. Therefore they need to build their energy reserves during their year -long residence. This energy is stored in their giant body. When they go on such a long distance journey, they get energy from this store. The same energy is also used for their sexual intercourse, a child, and then the child’s upbringing, before they come back to the water area of ​​California in spring and summer and start searching for food.

Whales eats cills and fish that can collect in large groups. However, their diet is different. Where blue whales only eat krill, humpback whales eat small fish like Krill and Ankovi that come in large groups. If the hunting species are more abundant and more dense, the whale can seek food more efficiently. Every year the conditions of food seeking food and the availability of hunting vary dramatically. We wanted to know whether these changes in the ecosystem are reflected in the behavior of singing whales?

During the study, it was found that the three whale species sang the lowest during the heat, and sang more when the situation improved in the next two years, when enough food was re -available for them. These patterns gave the first indication that the song of the whale could be closely related to the available food. Notable, Whale’s song is an indicator of the availability of fodder.
