October Big Day, 2023
How to participate
- Get an eBird account: eBird is a worldwide bird checklist program used by millions of birders. It’s what allows eBird 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 October 14. It’s that simple! October Big Day runs from midnight to midnight in your local time zone. You don’t need to be a bird expert, or go out all day long. You can report birds from anywhere in the world—even 10 minutes in your backyard will help.
- Enter what you see and hear on eBird: You can enter your sightings via the eBird website or—even easier—download the free eBird Mobile app. The app allows you to keep and submit lists while you’re still out birding, explore nearby Hotspots, and will even track of how far you’ve walked so you can focus on watching birds.
Finding birds and keeping checklists is easy with the free eBird Mobile app. Download for iOS or Android.
