Mark your calendars for October Big Day—10 Oct 2026! Like Global Big Day, October Big Day is an opportunity to celebrate our shared love of birds. Last October, 900,000 people united for a single day of birding. Can we beat that number and make this year the first October Big Day with more than a million people enjoying birds together?

Wherever you are on 10 October, take a few minutes to enjoy birds and share what you find. Participate from anywhere—even from home! By taking part in October Big Day you’re also celebrating Global Bird Weekend and World Migratory Bird Day. Be a part of the global team and help set new records for October birding.

1. Go birding on 10 October: 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. October Big Day runs from midnight to midnight in your local time zone. You can report what you find from anywhere in the world.
2. Share what you find: Log your October Big Day observations with eBird or Merlin to make them count! Make sure to submit your observations before 13 October to be included in the official results.
