To be honest, we do not know exactly if they can be called songs (in the sense of the songs that come to mind) however they managed to rank in the Top5 of the most successful albums in Australia.
The album, entitled "Songs of Disappearance" consists of birds chirping and was a success on the ARIA charts for the most successful songs and albums in Australia over the years.
The songs and tweets feature 53 endangered species of rare birds in Australia. They were collected for nearly 4 decades by wildlife expert David Stewart, who spent hours hiding in remote parts of Australia to record tweets.
The success of the album comes after a campaign on social networks, thanks to which it managed to become the first album of its kind to rank so high in the rankings.
Appendix: According to a UK study , a considerable number of people had heard songs with birds chirping during the quarantine, and many said that this comforted and calmed them in times of crisis. In other words, bird songs have been shown to bring mental health benefits.
