Every year for the last four years Global Big Day has set new heights for a single day of birding. This massively international collaborative birding event has been so great we want to have another worldwide eBird Big Day in October. Why October? Because spring is rejuvenating the southern hemisphere and the northern reaches of the world are in the midst of migration. No matter where you are, we’re confident you can find some great birds on 6 October. Let’s see what we can find together on the first October Big Day!
How to participate
- Get an eBird account: eBird is a worldwide bird checklist program used by hundreds of thousands 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 free.
- Watch birds on 6 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 counts. 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 in 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 out birding, and the app will even keep track of how far you’ve walked, so you can just 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 9 October for 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 100 countries. Stats will be updated in real-time on our October Big Day page.
