October Big Day is a great opportunity to participate in a global citizen science effort. At the most basic level, participation requires at least 15 minutes of birdwatching and recording your observations in eBird. It’s that easy! So if you are looking for another excuse to go out and birdwatch on an autumn weekend, this is a great one.

Find all the details and helpful resources about taking part in the October Big Day on the eBird website.
