As the pandemic confined us all to our rooms, distancing us from the outside world, many turned to social media to reflect on the little things about nature they barely observed in the life before Covid-19. From reposted pictures of mountains and the wide blue sky, to the plants in the balcony and glimpses of chirpy birds on grilled windows, the internet was replete with visuals of nature and wildlife.

Noticing a sudden surge in the number of people noticing birds in their backyard, two bird enthusiasts and researchers, Adithi Muralidhar and Ravi Sinha, from the Homi Bhabha Centre for Science Education (HBCSE), came together to create an online audio library for bird calls that would enable people to listen to and identify bird calls from their home.
