On Sunday, 15 March 2026, birdwatchers across India will unite to celebrate Dawn Chorus Day by recording and sharing the magical symphony of birdsong. Participants can join from rooftops, backyards, fields, or forests, contributing recordings to eBird checklists that will help expand Merlin Sound ID’s database of Indian species.
The Birdwatchers’ Society, in collaboration with Pentax Binoculars, invites enthusiasts nationwide to take part in Dawn Chorus Day. This annual celebration of birdsong offers a unique opportunity to document avian vocalizations, strengthen citizen science, and enjoy the beauty of nature at first light.
How To Record Bird Vocalizations
Participants can use external recorders or smartphone microphones. Apps such as Merlin and Smart Recorder allow audio capture in .WAV format. Once recorded, files can be trimmed and normalized using free software like Oceanaudio or Audacity before uploading to eBird checklists. Interesting recordings may also be shared directly via email to birdwatcherssocietywb@gmail.com.
Creating eBird Checklists
Start your first checklist just before dawn, continuing for up to two hours after sunrise. Each checklist should be exactly 15 minutes long, with complete counts of all birds identified by sound or sight. Share your lists with the eBird ID “dcindia” to contribute to the collective dataset.
Key Highlights
* Dawn Chorus Day scheduled for Sunday, 15 March 2026
* Recordings in .WAV format recommended for quality and compatibility
* Free editing tools like Audacity and Oceanaudio suggested for processing
* Checklists must be 15 minutes long, starting at first light
* Uploads will train Merlin Sound ID, expanding beyond 239 Indian species
* Recordings also archived in the Macaulay Library for global access
Why It Matters
Uploading sound recordings helps train Merlin Sound ID, a powerful tool that identifies bird species by song. With India’s rich avian diversity, contributions from participants will expand the database, ensuring future birders can instantly recognize the chorus around them. Beyond science, Dawn Chorus Day fosters appreciation for nature’s rhythms and strengthens community engagement.
