We recognize that COVID-19 continues to impact our communities. Even if your local conditions have improved, we always encourage everyone to put safety first, follow local guidelines, and bird mindfully. You can bird from home and still participate in October Big 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.
- Use eBird Canada: eBird has portals for many different regions and countries and you can get Canadian specific content by visiting eBird Canada
- Watch birds on 9 October. 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 our 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. Please submit your eBird checklists before 13 October to be included in our initial results announcement. You can even change the portal to eBird Canada in the app by going to Settings then Portal.
- 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 reports from more than 160 countries. Stats will be updated in real-time on our October Big Day page
