Global Big Day is an annual celebration of the birds around you. No matter where you are, join us virtually on 13 May, help celebrate World Migratory Bird Day, and share the birds you find with eBird.

Participating is easy—you can even be part of Global Big Day from home. If you can spare 5 or 10 minutes, report your bird observations to eBird online or with our free eBird Mobile app.

This corresponds with Birdathon as well.
