Going outside to listen to the sounds of a variety of birds may help people to be happier. Two studies have shown that listening to a variety of birdsong may improve human happiness.
The first study by researchers at slotxo California Polytechnic State University, or Cal Poly, looked at how bird singing affects people walking through parks in Colorado.
Danielle Ferraro, a biology graduate student who led the study at Cal Poly University, said there may be an evolutionary reason for that. Why do we humans like birdsong? This may be that when we hear the birds sing. will make sense of the signs of safety
in some parts of the world The chirping of birds can be a sign that spring and good weather is coming. And that bird diversity can mean a good environment, too.
Ferraro explains the study: She and her colleagues uncovered the sounds of birds native to the recorded area. Follow a hiking trail in Boulder Park, Colorado.
over the course of several weeks The researchers turned on the recorded bird sounds at the same time every day. without opening at any other time They then talked to the trekkers after they passed by.
Hikers who can hear the recordings of various birds reported feeling happy More than a group of people who can only hear the sounds of natural birds. Researchers point out Both the birdsong and the biodiversity can help people to be happier.
Ferraro explains that she used native birds in the study because it sounded the most natural. The researchers will conduct the study in the summer, which is important. Because spring is the breeding season for most birds. And if the birds chirp during the breeding season, it can disturb them.
The study is published in the December 2020 issue of the journal Proceedings of the Royal Society B.
For a recent second study, the journal Science Daily reported that scientists in Germany conducted the first study that Will natural diversity make people in Europe happier?
The researchers looked at the 2012 Quality of Life Survey of 26,000 adults in 26 European countries to see if the presence of a variety of bird species could increase the likelihood of a bird species. Does the environment affect their life satisfaction?
Joel Methorst is a researcher at the Senckenberg Center for Biodiversity and Climate Research, iDiv German Center for Integrative Biodiversity Research and at Goethe University in Frankfurt. The head of the study said Europeans were very happy. especially if their environment has a high diversity of animal species.
It was also found that The happiest Europeans are those who can come in contact with a variety of birds in their daily lives. Or living in an environment close to nature, which is the habitat of many animals.
A study published in the December 2020 issue of the journal Ecological Economics states that if bird singing has a positive effect on human mental health, We should add more types of birds singing.
