How to Participate
Get an eBird account: eBird is a worldwide bird checklist program used by millions of birders. It’s what allows everyone’s sightings to be compiled into a single massive Global Big Day list—while at the same time collecting the data to help scientists better understand birds. Sign up here. It’s 100% free from start to finish.
Watch birds on 8 May: It’s that simple. You don’t need to be a bird expert or go out all day long, even 10 minutes of birding from home counts. Global Big Day runs from midnight to midnight .
Enter what you see and hear in eBird: You can enter your sightings via the eBird website or download the free eBird Mobile app to make submitting lists even easier. Please enter your checklists before 11 May to be included in our initial results announcement.
Watch the sightings roll in: During the day, follow along with sightings from more than 170 countries in real-time on eBird’s Global Big Day page.
