From CornellLab of Ornithology
In our ongoing effort to push the boundaries of a Big Day, we’re inviting everybody around the world to join together and participate in our Global Big Day to support global conservation.
How to Participate
Submit Your Data to eBird on May 13. It’s that simple. If you submit your birds to eBird they count. Learn how to take part. Don’t worry — you don’t need to be a bird expert, or to go out all day long. Even a half hour checklist from your backyard will help. Of course, you are welcome to spend the entire day in the field, but know that it is not required! Please enter your data as soon as you can, preferably by Tuesday, May 16.
