①Researchers have long tried to understand the advantages of watching birds. A study in Scientific Reports last October in 2022, found that seeing or hearing these birds improved people's feelings of happiness for up to eight hours. And a study in 2020 showed human's happiness even has something to do with the number of different bird kinds around people's homes and towns. Another research in 2017 supported the idea that birds are good for human's brain. All the researches above show that birdwatching is good for mental（心理的） health.
