Every October, birdwatchers from every corner of the globe unite for one of the most exciting dates on the birding calendar: October Big Day. This year, the event will take place on 11 October 2025, bringing together beginners, experts, and nature lovers to enjoy birds while contributing to important scientific data. Whether you have an entire day or just a few spare minutes, your sightings can make a difference.
What Is October Big Day?
October Big Day is a worldwide birdwatching event organized through eBird, a global platform that collects bird observations from enthusiasts everywhere. The goal is simple yet powerful—compile one massive list of bird species seen across the world in a single day. Along the way, this shared effort helps scientists track bird populations, migration patterns, and conservation needs.

Why Your Participation Matters
Every bird sighting, no matter how common the species, adds valuable information to a growing pool of scientific data.
