Meet the author of the new "bird hit" — the rock Sparrow
Perhaps the most melodic of the animals of our planet are birds. After all, their song we hear in the days of nature walks — the beautiful chirping is directly associated with calmness and tranquility. Each species of bird has its own song that is constantly being improved and turned into a kind of hits the bird world. Amateur birdwatchers regularly record the singing of these feathered creatures and spread to the Internet, allowing recently revealed that over the last 50 years the rock sparrows (Zonotrichia albicollis) significantly changed the manner of his singing. First, the new song originated in Canada and then spread to different corners of the world. It is almost the same as the distribution of the musical hit in the human world.

To store records of singing birds, information on their numbers and other interesting data, the Internet is special . A group of canadian scientists led processor Ken Otter (Ken Otter) have used posted online records of the birds and studied the sounds 1785 males rock sparrows. In the records of the 1950-ies these creatures almost always ended his songs with three notes, like "TA-TA-TA". But somewhere between 1960 and 2000, some individuals began to finish his singing only two notes, "TA-TA".
the video shows the singing three notes and two
The Researchers thought it was a very interesting phenomenon, so they decided to hold one of a kind scientific work, the results of which were published in the scientific . As it turned out, a new song with the end on two notes originated about half a century ago in the Rocky mountains, which pass through Canada and in some us States. Apparently, the new sound so much like birds that updated the song literally spread from mouth to mouth and reached various regions of our planet. It came to the point that today it is rare where you can hear the rock Sparrow finishes his singing legacy three notes.
Why the new song is so much like the birds, researchers are not yet clear. There is an assumption that singing a whole new tune, male sparrows are more likely to attract the attention of females. Realizing this, birds of pickup artists take a new melody adopted and are unwittingly teaching it to males from other regions. This radically changes the representation of scientists about the musical preferences of female birds, because previously it was believed that they respond better to familiar tunes.
White sparrows we do not live — they live in Canada and the North-Eastern United States
Does the manner of execution of songs from other bird species, researchers don't know yet. For that, again, you must dig in the library, with records of singing birds in different years and compare them with each other. Perhaps in this way you can even understand what the birds sing. It may be that to attract a mate, they use some songs, and to warn of the danger — absolutely others.
Singing nightingales
The Most beautiful song among the birds, perhaps, from the warblers. These creatures are the size of a Sparrow wintering in East Africa, but with the first warm days arrive in Russia. They are a very secretive way of life, so to see them sing is almost impossible. But to learn their songs is not too difficult, because they often mix the whistling of the party rumble, the cracks and other interesting sounds.
That the Internet is a library with various information about birds, is not surprising. This is truly amazing creatures that are silly only at first glance. At the end of 2019, I said, as the bird stalled from Icelandic Islands Grimes uses found on the ground stick to . Also with improvised tools know how to use ravens, because they use sticks for the extraction of insects from the ground. Seems to be something banal and uninteresting, but to watch it all in nature is very funny.
