Scientists discover the complexity of sparrow song

The exploration of the world has led men to take an interest in wildlife as well as flora. With this in mind, thanks to the expeditions and research carried out to better understand nature, discoveries surprises have been made. This is how a group of researchers made it possible to highlight the complexity of the song of sparrows. According to their investigationsthis little bird would have the ability to modulate the tone sounds it makes.

In fact, according to scientists, sparrows use their songs as a means of communication. Thus, depending on the case, different sounds and vibrations would be issued. In order to definitively confirm this theorywildlife experts worked closely with the scientists.

In addition, the results of the studies have been published in the journal Proceedings of the Royal Society B. Among the many researchers and scientists who participated in the research is Professor Stephen Newicki of the’Duke University.

A bird like no other

Indeed, the sparrow friquet is a common songbird throughout the region ofNorth America. The latter use their song to defend their territory and court their companions. When they woo, sparrows emit up to 12 different, two-second-long songs. Furthermore, these gentlemen also vary the order of their register every time they sing their discography.

Looking for answers

To find out if the birds deliberately mix their tunes, ornithologists from Duke University and theUniversity of Miami traveled to the woods of Pennsylvania. From microphones pointed at the trees were installed to record data.

After collecting more than 30 voicethey examined the visual spectrographs of the trilliums and analyzed the frequency and the order of each song. Scientists have found that more than one sparrow sang a given song, the more he put on time to come back to it. The researchers deduced that these birds do it to create a fashion effect and novelty when this song was played again.

Doubts remain

“For now, it’s just speculation if these sluggish song sparrows are giving Spotify a run for their money to keep a woman’s interest, but it highlights our similar approach to the gym” : said Professor Stephen Nowicki.

The latter added: “You know those 10 songs are going to keep you motivated, but if you’re going to run for 20 songs, why not mix them up so next time you don’t hear the same songs in the same order? » As a result, recordings and experiments continue to be performed in order to have better results reliable.
