¡Celebra las aves del mundo!

The Global Big Day is an annual birdwatching event hosted by the Cornell Lab of Ornithology to celebrate World Migratory Bird Day and contribute to an improved understanding of global bird populations.

Participation is easy and free! Anyone can join in from aywhere – as long as you have 5 or 10 minutes to spare. All you need to do is watch for birds and submit your observations to the eBird online or through the free mobile app (click on the logo below for more info). If you have the time, submit multiple lists throughout the day. You never know what you might find!
