About The Event
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. If you have more time, submit several checklists of birds throughout the day. You never know what you might spot. Your observations help us better understand global bird populations through products like these animated abundance maps brought to you by eBird Science.
