How many birds can be seen in a day? The traditional "big days" focus on the total species of a single team of birdwatchers: how many birds can be seen in a cart full of birders for a bird binge from midnight to midnight. Imagine if everyone came together as a team, how many birds could we see? Global Big Day answers that question.
For three consecutive years, Global Big Day has set an ever-increasing world record for the number of birds observed in one day, with more than 20,000 bird watchers who contributed sightings from more than 160 countries last year. On May 5, 2018, we want you to be part of the next world birdwatching record. All you have to do is spend a few minutes outside May 5, anywhere in the world, and send it to eBird. Each sighting counts
If you're new to eBird, do not worry! We recommend checking out the Merlin Bird identification application to help you identify your birds, and the eBird Mobile app makes it easy to figure out what you find and join in the fun.
No matter what you do: have fun, enjoy the birds you find and share your sightings on eBird. Can we surpass last year's result of 6637 species of birds and set a new record for a day of bird watching? It's in your hands. We are excited to see what we can achieve together for Global Big Day.
How to participate
Send your data to eBird on May 5
It is easy. If you send your birds to eBird they count. Use the website or the mobile application, whichever you prefer. Learn to participate Do not worry, you do not need to be a bird expert or go out all day. Even ten minutes from your backyard will help you. Of course, we invite you to spend all day in the field, but know that it is not mandatory! Enter your data as soon as possible, preferably before Tuesday, May 8.
Data entry is easy with the free eBird Mobile application. Download for iOS or Android.

During the Big Day, this page will be updated. You can follow Team Sapsucker in Colombia, Honduras and California, and track how many species have been seen around the world and in any region that interests you. Follow the live updates here.
Now is the time to start planning with your friends to find difficult species. Explore the "hot spots" of birdwatching in your area. Who will "get" yellow-billed magpie? Cardinal Vermillion? Cangrejo-Chorlito Plains-wanderer? Not all efforts should work towards the global total. Learn how to share Global Big Day with others.

Make your sightings count
Do not worry, every bird that enters eBird counts as part of Global Big Day. However, there are three ways you can make your sightings as valuable as possible. It is important to keep in mind that these are only suggestions, not requirements! 1. Send complete checklists. 2. Keep the counts of the birds you see. 3. Keep multiple checklists during the course of your bird watching: if you get into the car, finish that checklist and start a new one when you get to the next place.
