Global Big Day has become a May tradition for tens of thousands of eBirders: 24 hours to put your favorite park/county (LGA)/state/province country/continent on the global birding stage. Last year we couldn’t wait a full year between Global Big Days, and October Big Day was born. On 19 October, October Big Day is back! Can we beat last year’s total of 6,331 species on a single October day?
How to participate
- Get an eBird account: eBird is a worldwide bird checklist program used by millions of birders. It’s what allows us to compile everyone’s sightings into a single massive October Big Day list—while at the same time collecting the data for scientists to use to better understand birds. Sign up here. It’s 100% free.
- Watch birds on 19 October: It’s that simple. You don’t need to be a bird expert, or go out all day long. Even 10 minutes in your backyard will help. October Big Day runs from midnight to midnight in your local time zone. You can report birds from anywhere in the world.
- Enter what you see and hear on eBird: You can enter your sightings via our website or—even easier—download the free eBird Mobile app. You can enter and submit lists while you’re still out birding, and the app will even keep track of how far you’ve walked, so you can focus on watching birds. While you’re downloading free apps, try out the Cornell Lab’s Merlin Bird ID app for help with identification. Please enter sightings before 23 October to be included in our initial results announcement.
- Watch the sightings roll in: During the day, keep an eye on how the lists are growing in different parts of the world. Follow along with sightings from more than 150 countries. Stats will be updated in real-time on our October Big Day page.
